Short answers to skin questions.

Toothpaste is not an acne treatment. Ingredients like menthol, fluoride and baking soda can irritate the skin, and on Indian skin that irritation often leaves a darker mark than the pimple would have.

From Acne on Indian Skin: Causes, Treatment and What Actually Works

Acne is mainly driven by hormones, oil glands and genetics. Some people notice flares with high sugar foods or milk, but oily food and water intake are not proven direct causes.

From Acne on Indian Skin: Causes, Treatment and What Actually Works

Most acne treatments need 6 to 12 weeks of regular use before you can judge them. Stopping and switching products every week is one of the most common reasons acne seems not to respond.

From Acne on Indian Skin: Causes, Treatment and What Actually Works

It is best not to. Squeezing pushes inflammation deeper, raises the risk of scarring and very often leaves a brown or black mark that lasts months on darker skin.

From Acne on Indian Skin: Causes, Treatment and What Actually Works

Creams with retinoids, azelaic acid or vitamin C can fade brown and red marks and slightly improve texture, but they cannot fill pitted scars. Indented scars usually need in clinic procedures.

From Acne Scars Treatment: Options for Indian Skin Explained

Most people need several sessions spaced a few weeks apart, often combining more than one technique. The number depends on scar type, depth and how your skin responds.

From Acne Scars Treatment: Options for Indian Skin Explained

Many lasers can be used safely on Fitzpatrick III to VI skin when the right device and conservative settings are chosen by an experienced dermatologist. The main risk is temporary darkening, which is reduced with careful planning and sun protection.

From Acne Scars Treatment: Options for Indian Skin Explained

Active acne should be controlled first, because new pimples keep creating new scars. Your dermatologist may start some gentle scar treatments once acne is mostly under control.

From Acne Scars Treatment: Options for Indian Skin Explained

The back and chest have many large oil glands, and they are often covered by tight clothes, bags and sweat. Some people also have a yeast related folliculitis on the back that looks like acne.

From Back Acne and Body Acne: Causes and How to Clear It

A benzoyl peroxide wash used daily is one of the most recommended first steps. Leaving it on the skin for two to five minutes before rinsing helps it work better. It can bleach fabric, so use white towels.

From Back Acne and Body Acne: Causes and How to Clear It

No. Scrubbing with loofahs or harsh scrubs irritates the skin, worsens inflammation and increases the risk of dark marks. Gentle washing works better.

From Back Acne and Body Acne: Causes and How to Clear It

Yes. Deep pimples on the back, chest and shoulders can leave dark marks, depressed scars, or raised scars and keloids, which are more common on these areas in darker skin.

From Back Acne and Body Acne: Causes and How to Clear It

Fungal acne bumps tend to be small, all the same size, itchy, and clustered on the chest, back, shoulders or hairline. Regular acne has mixed lesions including blackheads, larger pimples and nodules, and is usually not itchy.

From Fungal Acne (Malassezia Folliculitis): Signs and Treatment

No. Malassezia yeast lives on almost everyone's skin. Fungal acne happens when conditions such as heat, sweat or certain medicines let it overgrow, not because it was caught from someone else.

From Fungal Acne (Malassezia Folliculitis): Signs and Treatment

Relapses are common because the yeast is a normal part of the skin. Your dermatologist may suggest a maintenance plan, such as using an antifungal wash regularly during hot, humid months.

From Fungal Acne (Malassezia Folliculitis): Signs and Treatment

Please do not. Combination creams containing steroids are widely sold in India but can worsen fungal infections and cause steroid acne. Use treatment advised by a doctor.

From Fungal Acne (Malassezia Folliculitis): Signs and Treatment

No. Many women with jawline acne have normal hormone levels; their oil glands are simply more sensitive to normal androgens. PCOS is more likely when acne comes with irregular periods, excess facial or body hair, scalp hair thinning or weight changes.

From Hormonal Acne in Women and PCOS: Signs, Causes and Treatment

Certain combined oral contraceptives can help hormonal acne, but they are not right for everyone and acne may return after stopping. A doctor should check your health history before prescribing them.

From Hormonal Acne in Women and PCOS: Signs, Causes and Treatment

In women with PCOS who are overweight, modest weight loss and regular exercise can improve insulin resistance and hormone balance, which may help acne. Diet changes work best alongside proper skin treatment, not instead of it.

From Hormonal Acne in Women and PCOS: Signs, Causes and Treatment

Hormone shifts in the days before a period can increase oil production and inflammation. Many women notice a flare in the week before menstruation.

From Hormonal Acne in Women and PCOS: Signs, Causes and Treatment

The British Association of Dermatologists explains that it is licensed for severe acne in people over 12 when other treatments have not worked or when there is a risk of permanent scarring. Your dermatologist may sometimes recommend it in other situations and should explain why.

From Isotretinoin for Acne: What Patients Should Know

Isotretinoin can cause serious problems with how a baby develops. The NHS states that anyone who could become pregnant must use contraception from at least 1 month before starting, throughout treatment, and for at least 1 month after stopping.

From Isotretinoin for Acne: What Patients Should Know

The British Association of Dermatologists says research does not give a clear answer on whether isotretinoin causes mental health problems, while acne itself is linked to anxiety and depression. Because of the possible risk, mood is monitored, and you should seek help urgently if you have thoughts of self harm.

From Isotretinoin for Acne: What Patients Should Know

The BAD notes that most people find their acne stays better for several years after finishing the course. Some people need further treatment later, which your dermatologist can discuss.

From Isotretinoin for Acne: What Patients Should Know

No. Isotretinoin needs a dermatologist's assessment, pregnancy prevention where relevant, regular check ups and blood tests. Taking it without supervision exposes you to avoidable risks.

Poor sleep can make dark circles look worse, mainly through puffiness and shadowing, but many people have dark circles because of genetics, pigment or under eye structure, even with good sleep.

From Dark Circles Under Eyes: Causes and Treatment for Indian Skin

Cool compresses can briefly reduce puffiness, but there is little evidence that potato, cucumber or tomato lightens pigment. Avoid lemon and other acidic remedies on delicate under eye skin.

From Dark Circles Under Eyes: Causes and Treatment for Indian Skin

Most dark circles can be improved rather than removed, and improvement is often partial. Because genetics and anatomy play a role, ongoing care is usually needed.

From Dark Circles Under Eyes: Causes and Treatment for Indian Skin

Not always. Under eye skin is thin and easily irritated, and irritation can make dark circles darker. Ask your dermatologist which products are suitable for this area.

From Dark Circles Under Eyes: Causes and Treatment for Indian Skin

Yes. Skin over the joints is often naturally a little darker on brown skin, and kneeling, leaning on elbows, dryness and sun can deepen it. It is usually harmless, but sudden or velvety darkening elsewhere should be checked.

From Dark Knees, Elbows and Lips: Causes and What Helps

Harsh scrubbing, lemon, baking soda and bleach can irritate the skin and often make pigmentation worse on brown skin. Gentle care and regular moisturising work better.

From Dark Knees, Elbows and Lips: Causes and What Helps

Common reasons include family tendency, sun exposure, frequent lip licking, smoking, and allergy or irritation from lipsticks, balms or toothpaste. Some medicines and medical conditions can also darken lips, so new or patchy darkening should be examined.

From Dark Knees, Elbows and Lips: Causes and What Helps

Dark, thick, velvety skin on the knuckles, neck or underarms can be acanthosis nigricans, which is often linked to insulin resistance. A doctor may suggest checking blood sugar and weight related risks.

From Dark Knees, Elbows and Lips: Causes and What Helps

Products of unknown composition, and any cream containing a steroid, should not be used on the lips or face without a doctor's advice. A dermatologist can recommend safer options after finding the cause.

From Dark Knees, Elbows and Lips: Causes and What Helps

Surface marks often fade within 3 to 12 months with sun protection and treatment. Deeper, grey blue marks can take longer, sometimes more than a year.

From Dark Spots After Pimples (PIH): How to Fade Them on Indian Skin

Most PIH is not permanent and slowly fades. It is different from true acne scars, which are dents or raised marks in the skin texture.

From Dark Spots After Pimples (PIH): How to Fade Them on Indian Skin

Lemon juice is acidic and irritating and can make spots darker. Aloe vera may soothe skin but has little proven effect on fading pigment.

From Dark Spots After Pimples (PIH): How to Fade Them on Indian Skin

Lasers are not usually the first choice for PIH on darker skin because they can trigger more pigmentation. A dermatologist may use them selectively when other treatments have not worked.

From Dark Spots After Pimples (PIH): How to Fade Them on Indian Skin

Usually not. Acanthosis nigricans is a change in the skin itself and does not wash off. Scrubbing harder only irritates the skin and can make it darker.

From Dark Underarms and Neck: Acanthosis Nigricans Explained

Not necessarily, but it is commonly linked to insulin resistance, which can come before type 2 diabetes. It is a good reason to have your blood sugar checked.

From Dark Underarms and Neck: Acanthosis Nigricans Explained

It often lightens when the underlying cause is managed, for example with weight loss and better blood sugar control. Improvement is gradual and may be partial.

From Dark Underarms and Neck: Acanthosis Nigricans Explained

Shaving, waxing, deodorant irritation and friction can cause a different kind of darkening called post inflammatory hyperpigmentation. A dermatologist can tell the two apart.

From Dark Underarms and Neck: Acanthosis Nigricans Explained

Freckles are small spots that darken in sunny months and fade when sun exposure is lower, and they often appear in childhood. Sun spots, or solar lentigines, are usually larger, stay the same through the year and tend to appear in adulthood after years of sun.

From Freckles, Lentigines and Sun Spots: Causes and Treatment

Treatments such as lasers, cryotherapy and peels can lighten or remove individual spots, but new spots can appear with further sun exposure. Daily sun protection is needed to maintain results.

From Freckles, Lentigines and Sun Spots: Causes and Treatment

Most are harmless. However, some melanomas can look like flat brown spots, so any spot that is new, changing, irregular, multicoloured or bleeding should be examined by a dermatologist.

From Freckles, Lentigines and Sun Spots: Causes and Treatment

Yes, though less often than in very fair skin. Lentigines on the face, hands and forearms are commonly seen in middle aged and older Indians with long term sun exposure, and they are often confused with melasma.

From Freckles, Lentigines and Sun Spots: Causes and Treatment

No. Creams of unknown composition, especially those containing steroids, can damage the skin. A dermatologist can prescribe suitable lightening treatment for a limited period if needed.

From Freckles, Lentigines and Sun Spots: Causes and Treatment

A handful of small randomised trials of oral and topical glutathione have shown modest lightening while it is used. Reviews note that questions about how long the effect lasts, the right duration of use and long term safety remain unanswered.

From Glutathione for Skin Whitening: Is It Safe and Does It Work?

There is no published evidence that intravenous glutathione lightens skin, and reviews describe serious safety concerns including liver dysfunction and severe allergic reactions such as anaphylaxis. The Food and Drug Administration of the Philippines has issued public warnings against its off label use for skin lightening.

From Glutathione for Skin Whitening: Is It Safe and Does It Work?

Glutathione is not an established treatment for melasma or post inflammatory hyperpigmentation. These conditions respond better to sun protection and treatments a dermatologist chooses for your specific diagnosis.

From Glutathione for Skin Whitening: Is It Safe and Does It Work?

Safety data for glutathione taken for skin lightening during pregnancy and breastfeeding is lacking. Speak to your obstetrician and dermatologist before taking any supplement for cosmetic reasons at these times.

From Glutathione for Skin Whitening: Is It Safe and Does It Work?

Melasma can often be lightened significantly, but it is a chronic condition that tends to return with sun, heat or hormonal triggers. Ongoing sun protection and maintenance treatment help keep it under control.

From Melasma Treatment for Indian Skin: What Works and What to Avoid

Only under a dermatologist's supervision and for a limited time. Unsupervised use of steroid containing lightening creams is a major problem in India and can cause thinning, redness, acne and worse pigmentation.

From Melasma Treatment for Indian Skin: What Works and What to Avoid

Lasers are not a first line treatment for melasma. On Indian skin they can sometimes worsen pigmentation, so they are used selectively, at gentle settings, and usually alongside topical treatment.

From Melasma Treatment for Indian Skin: What Works and What to Avoid

Melasma that appears during pregnancy sometimes fades over the months after delivery, but it often persists. Strict sun protection during and after pregnancy helps.

From Melasma Treatment for Indian Skin: What Works and What to Avoid

Heat and visible light also worsen melasma, not just UV. A tinted sunscreen with iron oxides, reapplication, shade, and hats offer better protection than sunscreen alone.

From Melasma Treatment for Indian Skin: What Works and What to Avoid

Usually not. Pale, slightly scaly, poorly defined patches on the cheeks of children are most often pityriasis alba, which is linked to dry skin and atopic tendency and fades with time. Vitiligo patches are chalk white with sharp borders, so a dermatologist can usually tell them apart on examination.

From White Patches on Face: Pityriasis Alba, Versicolor or Vitiligo?

It is not considered contagious in the usual sense. It is caused by an overgrowth of Malassezia yeast that normally lives on everyone's skin, and it becomes more common in hot, humid weather and in people who sweat a lot.

From White Patches on Face: Pityriasis Alba, Versicolor or Vitiligo?

In tinea versicolor the colour can take weeks to months to return even after the yeast is cleared. Persistent pale patches do not necessarily mean the treatment failed, which is why sun protection and patience matter.

From White Patches on Face: Pityriasis Alba, Versicolor or Vitiligo?

No. Tanning makes the surrounding skin darker and the pale patches more noticeable. Gentle sun protection is usually advised for both pityriasis alba and tinea versicolor.

From White Patches on Face: Pityriasis Alba, Versicolor or Vitiligo?

Often yes. Examination in good light, a Wood lamp, dermoscopy and sometimes a simple skin scraping tested under the microscope (KOH test) are usually enough. A biopsy is needed only occasionally.

From White Patches on Face: Pityriasis Alba, Versicolor or Vitiligo?

No. It is an autoimmune condition, not an infection, and cannot spread from person to person.

From Alopecia Areata: Causes and Treatment of Patchy Hair Loss

In many people with one or a few small patches, hair regrows within a year, sometimes without treatment. Extensive or long standing hair loss is harder to treat, and patches can recur, so outcomes vary.

From Alopecia Areata: Causes and Treatment of Patchy Hair Loss

Stress may act as a trigger in some people, but the underlying cause is autoimmune and genetic. Many people develop patches without any obvious stress.

From Alopecia Areata: Causes and Treatment of Patchy Hair Loss

Regrowing hair is often white or fine at first and usually regains its normal colour and thickness over time.

From Alopecia Areata: Causes and Treatment of Patchy Hair Loss

There is no reliable evidence for these, and some cause irritation or chemical burns on the scalp. It is better to have the patch examined first.

From Alopecia Areata: Causes and Treatment of Patchy Hair Loss

Usually not. Dandruff flakes are often oily and yellowish, and the condition is linked to scalp oil and yeast. A truly dry scalp gives fine white flakes without much redness.

From Dandruff and Seborrheic Dermatitis: Causes and Treatment

No. Oil can feed Malassezia yeast, and leaving it on overnight often worsens flaking and itch. If you love oiling, keep it short and wash it out with a medicated shampoo.

From Dandruff and Seborrheic Dermatitis: Causes and Treatment

No. The yeast involved lives on almost everyone's skin. Dandruff reflects how your skin reacts to it, not an infection caught from someone else.

From Dandruff and Seborrheic Dermatitis: Causes and Treatment

Dandruff itself rarely causes significant hair loss, but intense scratching and scalp inflammation can increase shedding and breakage. Controlling the flaking usually helps.

From Dandruff and Seborrheic Dermatitis: Causes and Treatment

Many people start with two to three times a week, then reduce to once a week to prevent relapse. Your dermatologist can tailor this to your scalp and hair type.

From Dandruff and Seborrheic Dermatitis: Causes and Treatment

Losing roughly 50 to 100 hairs a day is considered normal. Women who wash less often may see more on wash days, which is not by itself a sign of disease.

From Hair Fall in Women: Causes, Tests and Treatment in India

Oiling can soften hair and reduce breakage from dryness, but it does not change the hair growth cycle, so it cannot stop shedding from illness, iron deficiency or hormones. Heavy oil left on an itchy, flaky scalp can make dandruff worse.

From Hair Fall in Women: Causes, Tests and Treatment in India

Hard water can leave hair rough and more prone to breakage at the shaft, but there is no good evidence that it causes hair to fall from the root. Breakage and true shedding look different and are treated differently.

From Hair Fall in Women: Causes, Tests and Treatment in India

Shedding after a high fever or serious illness is usually telogen effluvium, which often settles over several months once the trigger has passed. If it continues beyond about six months, it is worth checking for a second cause.

From Hair Fall in Women: Causes, Tests and Treatment in India

Your doctor may consider a blood count, ferritin (iron stores), thyroid tests, vitamin B12 and vitamin D, and hormone tests if there are signs of PCOS such as irregular periods, acne or facial hair.

There is no permanent cure, because the genetic tendency remains. Medical treatment can slow or stop progression and regrow some hair in many men, but the benefit fades if treatment is stopped.

From Male Pattern Baldness Treatment: What Actually Works

It can start as early as the late teens or twenties. Many Indian men first notice a receding hairline at the temples or thinning at the crown in their twenties and thirties.

From Male Pattern Baldness Treatment: What Actually Works

No. Helmets do not cause male pattern baldness. A very tight helmet worn for years may cause friction at the hairline, but a clean, well fitting helmet is not a cause of genetic hair loss.

From Male Pattern Baldness Treatment: What Actually Works

They do different jobs. A transplant moves existing hair to bald areas but does not stop ongoing loss of the remaining hair, so most surgeons advise medical treatment alongside it.

From Male Pattern Baldness Treatment: What Actually Works

Most men tolerate it, but a small proportion report sexual side effects or mood changes. These should be discussed with your dermatologist before starting, and any new symptom reported promptly.

From Male Pattern Baldness Treatment: What Actually Works

Results are slow. Sources suggest at least four months, and often six to twelve months, before the benefit can be judged, so it is important to continue as advised rather than stop early.

From Minoxidil for Hair Loss: What to Know Before You Start

A temporary increase in shedding in the early weeks is a recognised effect and usually settles with continued use. If shedding is heavy, prolonged or worrying, speak to your dermatologist rather than stopping on your own.

From Minoxidil for Hair Loss: What to Know Before You Start

The benefit is lost over the following months, and hair that grew because of the treatment is usually shed. This is why it is seen as a long term treatment.

From Minoxidil for Hair Loss: What to Know Before You Start

Yes. It is used for female pattern hair loss, but women may be more likely to notice unwanted facial hair, and it is usually avoided in pregnancy and breastfeeding. Your dermatologist will choose a suitable option.

From Minoxidil for Hair Loss: What to Know Before You Start

Minoxidil tablets are a blood pressure medicine, and low dose use for hair loss is a prescription decision that needs medical assessment and monitoring. Never take blood pressure tablets for hair without a doctor's advice.

The American Academy of Dermatology says shedding is often noticed about two months after giving birth and usually peaks about four months after delivery. Most women regain normal fullness by their child's first birthday, and many sooner.

From Postpartum Hair Loss: Why It Happens and When It Stops

Postpartum shedding is not true hair loss. The hair follicles keep working, and new hair grows back. If hair does not return to normal after a year, see a dermatologist, as another cause may be involved.

From Postpartum Hair Loss: Why It Happens and When It Stops

Iron deficiency is a known trigger of hair shedding, and the NHS lists pregnancy as a common cause of iron deficiency anaemia. A doctor can check your levels with a blood test before you start supplements.

From Postpartum Hair Loss: Why It Happens and When It Stops

No product has been shown to stop postpartum shedding, which settles on its own. The AAD suggests a volumising shampoo and a light conditioner on the ends of the hair to make hair look fuller in the meantime.

From Postpartum Hair Loss: Why It Happens and When It Stops

Some hair loss medicines are not suitable while breastfeeding. Do not start any medicine or medicated lotion without asking your doctor.

An Indian study in the International Journal of Trichology describes premature greying as occurring before 20 years in white populations, 25 years in Asians and 30 years in Africans.

From Premature Grey Hair: Causes, Tests and What Can Help

Indian case control studies have found lower vitamin B12 levels, along with lower folic acid, biotin and ferritin, in young people with premature greying compared with controls. These studies show an association, not proof that supplements will reverse greying.

From Premature Grey Hair: Causes, Tests and What Can Help

Supplements are worth taking only if a blood test shows a deficiency. The studies linking premature greying with low nutrient levels show an association, not proof that supplements will reverse greying, so safe hair colouring remains the main option for covering grey hair.

From Premature Grey Hair: Causes, Tests and What Can Help

Based on Indian studies, a doctor may consider haemoglobin and ferritin, vitamin B12 and folate, vitamin D and calcium, and thyroid tests including thyroid antibodies, depending on your history.

From Premature Grey Hair: Causes, Tests and What Can Help

Usually not, especially if it runs in the family. However, studies link it with thyroid autoimmunity and nutritional deficiencies, and white patches of hair with white skin can be a sign of vitiligo, so a check up is reasonable.

From Premature Grey Hair: Causes, Tests and What Can Help

Odour can return within hours in hot, humid weather because bacteria on the skin quickly break down fresh sweat, especially in the underarms, groin and feet. Antiperspirants, thorough drying, frequent change of clothes and treating excess sweating usually help more than extra perfume.

From Body Odour and Bromhidrosis: Causes and What Helps

A deodorant masks or reduces odour, often with fragrance or antibacterial ingredients. An antiperspirant reduces the amount of sweat, which leaves less for bacteria to break down.

From Body Odour and Bromhidrosis: Causes and What Helps

Strong smelling foods such as garlic, onions, some spices and alcohol can temporarily change body odour in some people. Diet is rarely the only cause, but cutting back may help if you notice a link.

From Body Odour and Bromhidrosis: Causes and What Helps

Usually it is not. However, a sudden change in body odour, a fishy or unusual smell, or odour along with weight loss, excessive thirst or fever should be checked by a doctor, as it may relate to diabetes, liver or kidney disease, infections or rare metabolic conditions.

From Body Odour and Bromhidrosis: Causes and What Helps

It can help some people, because hair holds sweat and bacteria. Shaving, trimming or laser hair reduction are all options, but they should be done gently to avoid irritation.

They are caused by the same virus. Chickenpox is the first infection, usually in childhood, and the virus then stays dormant in nerve cells. Shingles happens when it reactivates later, causing a painful rash in one band on one side of the body.

From Chickenpox and Shingles: Skin Care, Itch Relief and Scars

You cannot catch shingles from someone, but a person who has never had chickenpox or the vaccine can catch chickenpox from fluid in shingles blisters. Keep blisters covered and avoid contact with pregnant women, newborns and people with low immunity until they crust.

From Chickenpox and Shingles: Skin Care, Itch Relief and Scars

Most spots heal without lasting scars, but scratching, picking and secondary bacterial infection increase the risk. Brown skin may also have dark or light marks that fade slowly over months.

From Chickenpox and Shingles: Skin Care, Itch Relief and Scars

Aspirin should never be given to children because of the risk of Reye syndrome, and DermNet advises avoiding anti inflammatory painkillers such as ibuprofen in chickenpox. Ask your doctor about paracetamol and the right dose for your child.

No. Eczema cannot spread from person to person. Infected eczema can carry bacteria or viruses, but the eczema itself is not catching.

From Eczema (Atopic Dermatitis) in Adults and Children

Many children improve as they grow, often by school age or the teenage years. Some continue to have dry, sensitive skin or flares into adulthood.

From Eczema (Atopic Dermatitis) in Adults and Children

Do not cut out foods without medical advice. Food allergy plays a role only in some children, usually infants with severe eczema, and unnecessary restriction can affect growth and nutrition.

From Eczema (Atopic Dermatitis) in Adults and Children

When prescribed by a doctor in the right strength, for the right site and duration, topical steroids are a safe and effective part of eczema care. The problems come from unsupervised, long term or wrong strength use, especially on the face.

From Eczema (Atopic Dermatitis) in Adults and Children

Some people find virgin coconut oil soothing, but plain fragrance free moisturisers made for sensitive skin are usually more reliable. Mustard oil and oils with added fragrance can irritate eczema skin.

Paraphenylenediamine (PPD) is a chemical used in many permanent and some semi-permanent hair dyes. DermNet notes that darker shades contain higher concentrations of PPD, and that allergy is more common in people with skin of colour, who often use darker dyes.

From Hair Dye Allergy: PPD, Patch Tests and the Kala Mehndi Danger

Natural henna is orange to red brown. Black henna pastes often have PPD added, and the NHS notes they contain high levels of it. They can cause severe blistering reactions and make you allergic to hair dye in future.

From Hair Dye Allergy: PPD, Patch Tests and the Kala Mehndi Danger

Follow the instructions in the pack, which usually involve applying a small amount of mixed dye behind the ear or on the inner elbow and leaving it for 48 to 72 hours. Do not use the dye if you get any itching, redness or rash, and remember that a negative test does not completely guarantee safety.

From Hair Dye Allergy: PPD, Patch Tests and the Kala Mehndi Danger

DermNet explains that once you react to PPD, lifelong sensitisation is likely. Some people tolerate alternatives such as dyes based on para-toluenediamine sulfate, but only after testing, ideally under a dermatologist's guidance.

From Hair Dye Allergy: PPD, Patch Tests and the Kala Mehndi Danger

Seek emergency care immediately if your lips, mouth, tongue or throat swell, you have difficulty breathing or swallowing, or you feel faint or confused. These can be signs of anaphylaxis, which the NHS says is rare but possible.

Sweating in heat, humidity or exercise is normal. Hyperhidrosis is suspected when sweating soaks your hands, feet or clothes even in an air conditioned room, at rest, or during winter, and interferes with daily life such as writing, shaking hands or using a phone.

From Hyperhidrosis: When Sweating Is More Than the Indian Heat

Most hyperhidrosis that starts in childhood or the teens and affects the hands, feet or underarms is primary and not linked to another disease. Sweating all over the body, night sweats, or sweating that started suddenly in adulthood should be checked, as it can be linked to infections, thyroid problems, diabetes, medicines or other conditions.

From Hyperhidrosis: When Sweating Is More Than the Indian Heat

Surgery on the sympathetic nerves is reserved for severe cases where other treatments have failed. A common side effect is compensatory sweating, new heavy sweating elsewhere on the body, which can be permanent, so it needs careful discussion.

From Hyperhidrosis: When Sweating Is More Than the Indian Heat

Yes. Constant moisture can lead to foot odour, fungal infection and a bacterial condition called pitted keratolysis. Treating the sweating often helps these too.

From Hyperhidrosis: When Sweating Is More Than the Indian Heat

An ingrown hair bump usually appears where you shave, wax or pluck, and you may see a hair trapped under or looping into the skin. Pimples usually appear with blackheads and whiteheads on the face, chest or back and are not tied to hair removal.

From Ingrown Hair and Razor Bumps: Shaving, Waxing and Threading Tips

Digging into the skin can cause infection, scarring and dark marks. If a hair is clearly visible at the surface, a dermatologist can advise you, but repeated picking and squeezing should be avoided.

From Ingrown Hair and Razor Bumps: Shaving, Waxing and Threading Tips

Not necessarily. Both shaving and waxing, as well as threading and plucking, can lead to ingrown hairs. The method that suits you depends on your hair, skin and the area.

From Ingrown Hair and Razor Bumps: Shaving, Waxing and Threading Tips

Laser hair reduction reduces the number and thickness of hairs, which can reduce ingrown hairs over time. It must be done with settings suitable for brown skin by trained professionals.

From Ingrown Hair and Razor Bumps: Shaving, Waxing and Threading Tips

Brown skin tends to make extra pigment after any inflammation. Repeated bumps, picking and friction can leave post inflammatory dark marks that fade slowly once the bumps are controlled.

From Ingrown Hair and Razor Bumps: Shaving, Waxing and Threading Tips

Not always. Intertrigo starts as inflammation from friction and moisture, but it often becomes infected with candida yeast, bacteria or ringworm fungus. Each needs a different treatment, which is why a correct diagnosis matters.

From Intertrigo: Skin Fold Rash in the Groin, Under Breasts and Belly

Heat, sweat and skin rubbing on skin under the breasts create a warm, moist space where the skin breaks down and yeast can grow. Keeping the area dry, wearing a supportive cotton bra and placing a soft cotton cloth in the fold can help reduce recurrences.

From Intertrigo: Skin Fold Rash in the Groin, Under Breasts and Belly

A light dusting of a plain or doctor recommended antifungal powder on fully dry skin may help some people. Avoid caking thick layers of powder or using perfumed talc on raw, broken skin.

From Intertrigo: Skin Fold Rash in the Groin, Under Breasts and Belly

These combination creams are widely sold in India but can hide fungal infection, thin the delicate skin of folds and cause stretch marks. Use a cream only after a doctor has confirmed what is causing the rash.

From Intertrigo: Skin Fold Rash in the Groin, Under Breasts and Belly

People with higher body weight, diabetes, heavy sweating, limited mobility, incontinence, and those living or working in hot, humid conditions are more likely to develop intertrigo. Babies can also get it in neck and nappy folds.

From Intertrigo: Skin Fold Rash in the Groin, Under Breasts and Belly

Heat and humidity keep the groin warm and damp, which helps fungus grow. If the earlier infection was not fully cleared, or if clothes and towels still carry fungal spores, it can flare again as soon as sweating increases.

From Jock Itch (Tinea Cruris) in India: Why It Keeps Coming Back

Indian dermatologists strongly advise against these combination creams for jock itch. The steroid hides the itch while the fungus spreads, and in the groin it can cause permanent thinning and stretch marks.

From Jock Itch (Tinea Cruris) in India: Why It Keeps Coming Back

Yes. Tinea cruris affects women too, often in the groin, inner thighs, under the belly fold and buttocks, especially in hot weather.

From Jock Itch (Tinea Cruris) in India: Why It Keeps Coming Back

It is not classed as an STI, but the fungus can pass between partners through close skin contact and shared towels or clothes, so a partner with symptoms may also need treatment.

From Jock Itch (Tinea Cruris) in India: Why It Keeps Coming Back

No. Itching often settles before the fungus is cleared. Follow the duration your dermatologist advises, which is often some time beyond the point the skin looks normal.

From Jock Itch (Tinea Cruris) in India: Why It Keeps Coming Back

No. Keratosis pilaris is not an infection and cannot spread to other people. It is a genetic tendency in how the skin forms keratin.

From Keratosis Pilaris (Chicken Skin): Causes and Gentle Care

No. Harsh scrubs, loofahs and rubbing usually make keratosis pilaris redder, darker and more irritated. Gentle chemical exfoliation with a moisturiser works better.

From Keratosis Pilaris (Chicken Skin): Causes and Gentle Care

It often improves in adulthood, especially after the teenage years, but some people have it for life. It may get worse in dry or cold weather.

No. Lichen planus cannot be passed to another person by touch, kissing, sharing food or sexual contact.

From Lichen Planus: Skin, Mouth and Nail Symptoms Explained

Skin lichen planus is not cancer. Long standing oral lichen planus, especially the erosive type, carries a small increased risk of mouth cancer, which is why regular mouth checks and avoiding tobacco are recommended.

From Lichen Planus: Skin, Mouth and Nail Symptoms Explained

On brown skin, lichen planus often heals with dark brown or grey patches because of pigment released during inflammation. These marks can last for months or longer, but usually fade slowly.

From Lichen Planus: Skin, Mouth and Nail Symptoms Explained

Stress is not a proven direct cause, but some people notice flares during stressful periods. The exact trigger is often not found.

From Lichen Planus: Skin, Mouth and Nail Symptoms Explained

Tobacco and areca nut use irritate the lining of the mouth and are linked to mouth cancer. Anyone with white patches or sores in the mouth should stop these and see a doctor or dentist.

Milia are tiny cysts with a thin covering of skin over them and no opening to the surface, so squeezing only bruises the skin. A dermatologist removes them by making a tiny opening first, under clean conditions.

From Milia, Whiteheads and Skin Tags: What Are These Bumps?

Not necessarily. Skin tags are very common, especially with age and in skin folds. However, many skin tags, particularly with dark velvety skin on the neck, can be linked to insulin resistance, so your doctor may suggest checking blood sugar.

From Milia, Whiteheads and Skin Tags: What Are These Bumps?

This is a common home practice in India, but it can cause pain, infection and bleeding, and it may be used on a growth that is not actually a skin tag. It is safer to have it removed by a doctor.

From Milia, Whiteheads and Skin Tags: What Are These Bumps?

Thick, occlusive creams around the eyes may contribute to milia in some people. Milia can also follow sun damage, burns, blistering or long term steroid cream use.

From Milia, Whiteheads and Skin Tags: What Are These Bumps?

No. Whiteheads are clogged pores filled with oil and dead skin and are part of acne. Milia are tiny keratin cysts that are not related to acne and do not respond to acne treatments in the same way.

From Milia, Whiteheads and Skin Tags: What Are These Bumps?

No. Psoriasis, injury from tight shoes, eczema, lichen planus and ageing can all cause thick or discoloured nails. This is why a nail clipping or scraping test is often done before starting long treatment.

From Nail Fungus (Onychomycosis): Why It Is Slow to Treat

Fingernails take around six months to grow out fully and toenails can take a year or longer. Treatment and the time to see a clear, healthy nail often follow this timeline.

From Nail Fungus (Onychomycosis): Why It Is Slow to Treat

Regular nail polish does not treat fungus and may hide changes. Home remedies such as vinegar, tea tree oil or garlic have limited evidence and rarely clear a well established infection.

From Nail Fungus (Onychomycosis): Why It Is Slow to Treat

Relapse and reinfection are common, especially if athlete's foot is not treated, feet stay damp, or shoes are not kept clean and dry. Ongoing foot care helps lower this risk.

From Nail Fungus (Onychomycosis): Why It Is Slow to Treat

It is usually not dangerous in healthy people, but it can cause pain and lead to skin infections. In people with diabetes or poor circulation, foot and nail problems should be checked early.

From Nail Fungus (Onychomycosis): Why It Is Slow to Treat

No. The patches are simply taped onto the skin, without needles. A positive test can cause an itchy red patch at that spot, which usually settles and can be treated if needed.

From Patch Test for Skin Allergy: What to Expect

It usually needs about three visits over roughly one week. Patches are applied at the first visit, removed and read after about two days, and read again a day or two later because some reactions take longer to appear.

From Patch Test for Skin Allergy: What to Expect

You should keep your back completely dry until the final reading, so avoid showers, swimming and heavy sweating. Many people manage with a careful sponge bath or a shallow bath that keeps the back dry.

From Patch Test for Skin Allergy: What to Expect

Some medicines can affect results, such as steroid tablets, other medicines that suppress immunity and strong steroid creams on the back. Do not stop any medicine without asking the doctor arranging the test. Antihistamines can usually be continued.

From Patch Test for Skin Allergy: What to Expect

No. Patch tests detect delayed allergic reactions from things touching the skin. Prick tests and some blood tests are used for immediate type allergies such as hay fever, some food allergies and hives.

From Patch Test for Skin Allergy: What to Expect

Prickly heat usually improves within a few days once you cool down and keep the skin dry. If it lasts more than a few days, becomes painful, or shows pus, see a doctor.

From Prickly Heat, Sweat Rash and Monsoon Skin Care in India

Some people find a light, fragrance free powder comfortable on intact skin. Avoid heavy layers in folds, avoid powders with strong menthol or fragrance on irritated skin, and never use powder on babies' faces where it can be inhaled.

From Prickly Heat, Sweat Rash and Monsoon Skin Care in India

Prickly heat appears as tiny, evenly spread bumps that come and go with heat. Fungal infections like ringworm form spreading, itchy rings or patches with a raised, scaly edge, often in the groin, waist or under the breasts.

From Prickly Heat, Sweat Rash and Monsoon Skin Care in India

It is best not to. Combination creams with steroids can make fungal infections spread and become harder to treat, a problem now very common in India.

From Prickly Heat, Sweat Rash and Monsoon Skin Care in India

No. Psoriasis cannot spread by touch, sharing food, swimming pools or living together. It is an immune condition, not an infection.

From Psoriasis: Symptoms, Triggers and Treatment Options

There is currently no permanent cure, and it tends to come and go. With the right treatment many people achieve clear or nearly clear skin for long periods.

From Psoriasis: Symptoms, Triggers and Treatment Options

No single food causes psoriasis. Losing excess weight, limiting alcohol and stopping smoking have the clearest evidence for improving it.

Yes. A proportion of people develop psoriatic arthritis, with joint pain, stiffness or swelling of fingers and toes. Early treatment helps protect the joints.

From Psoriasis: Symptoms, Triggers and Treatment Options

Oral or injected steroids can cause psoriasis to flare badly, sometimes into a severe widespread form, when they are stopped. They are generally avoided for psoriasis unless a specialist advises otherwise.

From Psoriasis: Symptoms, Triggers and Treatment Options

Common reasons are using steroid combination creams, stopping treatment as soon as itching settles, untreated family members, reinfection from clothes and towels, and sweating in tight synthetic clothing. Some newer fungal strains in India also respond more slowly to standard treatment.

From Ringworm (Tinea) in India: Why It Keeps Coming Back

No. Ringworm is caused by fungi called dermatophytes. The name comes from its ring shaped appearance.

From Ringworm (Tinea) in India: Why It Keeps Coming Back

Indian dermatologists strongly advise against these combination creams for fungal infection. The steroid hides the rash and lets the fungus spread, and long use can thin and permanently damage the skin.

From Ringworm (Tinea) in India: Why It Keeps Coming Back

Yes. It spreads through skin contact, shared towels, clothes and bedding, and sometimes from pets. Treating everyone affected at home helps stop the cycle.

From Ringworm (Tinea) in India: Why It Keeps Coming Back

It varies. Many cases in India now need several weeks of treatment, and your dermatologist may advise continuing for some time after the skin looks clear.

From Ringworm (Tinea) in India: Why It Keeps Coming Back

Yes. Rosacea is more often diagnosed in lighter skin, but it occurs in all skin tones. On brown skin the redness is harder to see, so burning, stinging, warmth and bumps may be the main clues.

From Rosacea and Sensitive Skin: Symptoms, Triggers and Care

No. Rosacea can cause pimple like bumps, but it does not cause blackheads or whiteheads, and many acne treatments can make rosacea worse.

From Rosacea and Sensitive Skin: Symptoms, Triggers and Care

Spicy food does not cause rosacea, but it is a common trigger for flushing in people who already have it. Hot drinks, heat, sun, alcohol and stress are other common triggers.

From Rosacea and Sensitive Skin: Symptoms, Triggers and Care

There is no permanent cure, but it can usually be controlled. Many people have long periods with few symptoms when they follow a gentle routine and treatment plan.

From Rosacea and Sensitive Skin: Symptoms, Triggers and Care

No. Seborrheic keratoses are benign growths and do not turn into cancer. However, some skin cancers can look similar, so a growth that is changing, bleeding or unusual should be examined.

From Seborrheic Keratosis, DPN and Age Spots: Harmless or Not?

This is likely dermatosis papulosa nigra, which often runs in families and is common in brown skin. The bumps usually start in adulthood and slowly increase in number with age.

From Seborrheic Keratosis, DPN and Age Spots: Harmless or Not?

A treated spot usually does not return, but new ones commonly appear over time because the tendency to form them remains.

From Seborrheic Keratosis, DPN and Age Spots: Harmless or Not?

No cream reliably removes raised seborrheic keratoses or DPN. Picking, cutting or applying caustic pastes can cause infection, scarring and dark marks, especially on Indian skin.

From Seborrheic Keratosis, DPN and Age Spots: Harmless or Not?

No. Flat age spots (solar lentigines) are sun related patches of increased pigment that are not raised. Some can later develop into a seborrheic keratosis, but they are managed differently.

From Seborrheic Keratosis, DPN and Age Spots: Harmless or Not?

Yes. Skin cancer is less common in darker skin, but it does occur. The American Academy of Dermatology notes that it is often found later in people with darker skin tones, which can make it harder to treat.

From Skin Cancer Signs in Darker Skin: When to Check a Mole

Acral lentiginous melanoma is a type of melanoma that arises on the palms, soles or under the nails. Research reviews describe it as the most frequently diagnosed melanoma subtype in some parts of Asia, Africa and Latin America, and it is not thought to be mainly caused by sun exposure.

From Skin Cancer Signs in Darker Skin: When to Check a Mole

A for asymmetry, B for an irregular border, C for varied colour, D for diameter usually larger than about 6 mm, and E for evolving, meaning a spot that is changing in size, shape or colour.

From Skin Cancer Signs in Darker Skin: When to Check a Mole

Most dark nail streaks in brown skin are harmless, but a new, widening or irregular dark band, especially if pigment spreads onto the skin around the nail, should be examined by a dermatologist.

From Skin Cancer Signs in Darker Skin: When to Check a Mole

The NHS says it is normal for new moles to appear, especially in children and teenagers, and for moles to darken slightly in pregnancy. A mole that changes in size, shape or colour, or bleeds or itches, should be checked.

From Skin Cancer Signs in Darker Skin: When to Check a Mole

Check the ingredients for names ending in -sone, -solone or -nide, such as clobetasol, betamethasone, mometasone, fluocinolone or hydrocortisone. Creams containing these are prescription medicines, even if they were sold over the counter.

From Steroid Creams and Fairness Creams: The Hidden Danger

Long term facial steroid use can make the skin dependent on it. Stopping suddenly often triggers a rebound flare of redness, burning, acne and itching, which is why stopping is best planned with a dermatologist.

From Steroid Creams and Fairness Creams: The Hidden Danger

Redness, acne and rosacea like changes often improve over weeks to months after stopping with proper treatment. Thinning, stretch marks and visible blood vessels may improve only partly, and some changes can be permanent.

From Steroid Creams and Fairness Creams: The Hidden Danger

Not all, but creams without clear labelling, those promising very quick results, and products bought loose or online from unknown sellers carry a higher risk of hidden steroids, mercury or high strength bleaching agents.

From Steroid Creams and Fairness Creams: The Hidden Danger

Yes, when used for the right condition, at the right strength, on the right body site and for the right duration, under a doctor's guidance. They are essential treatments for eczema, psoriasis and many other conditions.

Each individual welt usually fades within 24 hours, though new ones can keep appearing. Hives that continue on most days for more than six weeks are called chronic urticaria.

From Urticaria (Hives): Causes, Relief and When to Worry

No. Acute hives can follow infections, medicines or foods, but most chronic hives are not caused by a food or external allergy and are thought to involve the immune system itself.

From Urticaria (Hives): Causes, Relief and When to Worry

Usually not. Food allergy is an uncommon cause of chronic hives, and strict diets rarely help. Keep a diary and discuss any clear pattern with your doctor.

From Urticaria (Hives): Causes, Relief and When to Worry

Short courses of oral steroids are occasionally used for severe flares under medical supervision, but repeated steroid injections for chronic hives carry serious side effects and are not recommended as routine treatment.

From Urticaria (Hives): Causes, Relief and When to Worry

Seek emergency care if hives come with swelling of the tongue or throat, difficulty breathing or swallowing, wheezing, dizziness or fainting, as these can be signs of anaphylaxis.

No. Vitiligo cannot spread by touch, sharing food, utensils or towels, or living together. It is an autoimmune condition.

From Vitiligo: Causes, Treatment and Common Myths in India

There is no scientific evidence that any food combination causes vitiligo. Restrictive diets often make people miss out on nutrition without helping the skin.

From Vitiligo: Causes, Treatment and Common Myths in India

No. Leprosy is a bacterial infection that can cause light patches with reduced sensation. Vitiligo patches are usually milky white with normal sensation, and the two are completely different conditions.

From Vitiligo: Causes, Treatment and Common Myths in India

There is no permanent cure, but many people regain colour with treatment, especially on the face and neck. Results vary, and patches can return, so ongoing care helps.

A corn usually sits over a pressure point, hurts when pressed straight down and keeps normal skin lines. A wart on the sole often interrupts the skin lines, may show tiny black dots, and tends to hurt more when squeezed from the sides. A dermatologist can confirm which one it is.

From Warts, Molluscum and Corns: How to Tell Them Apart

In healthy children and adults it is usually harmless and often clears on its own over months, sometimes longer. Widespread or very large lesions in an adult can occasionally point to reduced immunity and should be checked.

From Warts, Molluscum and Corns: How to Tell Them Apart

Please do not. Cutting, burning with acids, or using blades can cause bleeding, infection and scars, and it can spread warts. People with diabetes should never self treat foot lesions.

From Warts, Molluscum and Corns: How to Tell Them Apart

Many warts, especially in children, eventually clear without treatment, though this can take months to a couple of years. Treatment may be considered if they are painful, spreading or bothersome.

It varies from person to person and with how deep the tan is. A tan tends to fade gradually as the skin renews itself, but it keeps coming back if the skin is exposed to strong sun every day without protection.

From Sun Tan Removal: What Actually Works on Indian Skin

Most home and salon de-tan treatments have little good evidence behind them. Lemon juice and harsh scrubs can irritate the skin, and on Indian skin irritation often leads to darker patches rather than lighter ones.

From Sun Tan Removal: What Actually Works on Indian Skin

Yes. The NHS states that there is no safe or healthy way to get a tan, and that a tan does not protect your skin from the harmful effects of the sun.

From Sun Tan Removal: What Actually Works on Indian Skin

Sunscreen does not bleach existing pigment, but it stops new tanning so that the existing tan can fade. It works best with shade and covering clothing, and needs reapplying about every two hours when you are outdoors or sweating.

From Sun Tan Removal: What Actually Works on Indian Skin

If dark patches stay for months, appear in a pattern on the cheeks, forehead or upper lip, or affect the neck and underarms with a velvety texture, it may be melasma, post inflammatory hyperpigmentation or acanthosis nigricans, which need a dermatologist's assessment.

From Sun Tan Removal: What Actually Works on Indian Skin

Yes. Darker skin burns less easily, but UV and visible light still cause tanning, uneven tone, melasma and darkening of acne marks, and skin cancer can still occur. Daily sunscreen is useful for every skin tone.

From Sunscreen Guide for India: SPF, PA Ratings and How to Apply

Not by much. SPF 30 filters about 97 percent of UVB rays and SPF 50 about 98 percent, so the extra numbers add very little. How much you apply and how often you reapply matters far more.

From Sunscreen Guide for India: SPF, PA Ratings and How to Apply

If you sit near a window, travel by car or spend time in bright rooms, UVA can reach your skin through glass. People with melasma or pigmentation often benefit from wearing sunscreen indoors too.

From Sunscreen Guide for India: SPF, PA Ratings and How to Apply

Mineral filters such as zinc oxide and titanium dioxide reflect light and can look chalky on brown skin. Tinted mineral sunscreens or well formulated chemical or hybrid sunscreens usually blend in better.

From Sunscreen Guide for India: SPF, PA Ratings and How to Apply

Usually not on its own, because people apply far less makeup or moisturiser than the amount used in SPF testing. Use a dedicated sunscreen as your last skincare step and treat SPF in makeup as a bonus.

Three steps are enough for most people: cleanser, moisturiser and sunscreen in the morning, and cleanser plus moisturiser at night. Extra serums are optional and should be added one at a time.

From Basic Skincare Routine by Skin Type: A Dermatologist's Guide

Yes. Skipping moisturiser can leave the skin barrier dry and irritated, especially if you use acne treatments. A light gel or fluid labelled non comedogenic is usually comfortable in Indian humidity.

From Basic Skincare Routine by Skin Type: A Dermatologist's Guide

Wash your face with a gentle cleanser, pat it dry and leave it bare for about an hour. If it looks shiny all over it is likely oily, if it feels tight it is likely dry, and if only the forehead and nose are shiny it is likely combination.

From Basic Skincare Routine by Skin Type: A Dermatologist's Guide

Twice a day and after heavy sweating is enough for most people. Washing more often, or with harsh soaps, tends to strip the skin and can make both dryness and oiliness worse.

From Basic Skincare Routine by Skin Type: A Dermatologist's Guide

Cold air holds less moisture, indoor heaters dry the air further, and long hot baths strip natural oils from the skin. Together these weaken the skin barrier, so it loses water faster and becomes rough and itchy.

From Dry Skin in Winter and Cracked Heels: A Practical Guide

Plain oils can help some people, but they are not suitable for everyone and some people react to them. Thicker fragrance free creams or ointments applied on slightly damp skin are a reliable option recommended by dermatologists.

Gentle use on softened, thick skin may help some people, but aggressive scraping, blades and cutting hard skin at home can cause injury and infection. People with diabetes should not cut or scrape their feet themselves.

From Dry Skin in Winter and Cracked Heels: A Practical Guide

See a doctor if cracks are deep, bleeding, very painful, red, hot or oozing, or if you have diabetes or poor circulation. Thick, scaly heels can also be due to fungal infection, eczema or psoriasis, which need specific treatment.

No treatment reliably removes stretch marks completely. Treatments can make them less noticeable, softer and closer to the surrounding skin colour, with results varying from person to person.

From Stretch Marks (Striae): What Actually Works and What Does Not

Massaging with oils or moisturisers is safe and may help with dryness and itching, but good evidence that any cream reliably prevents stretch marks is limited. Genetics and how fast the skin stretches matter a lot.

From Stretch Marks (Striae): What Actually Works and What Does Not

Generally yes. Early red, pink or purple marks tend to respond better to treatment than older, white or silvery marks.

People can carry mites for weeks before they start itching. If only the person with symptoms is treated, untreated family members can pass the mites back again.
