Anti-Ageing Skincare: What Actually Works and What Is Hype

The anti-ageing skincare with the strongest evidence is surprisingly simple: daily broad spectrum sunscreen, a retinoid used carefully at night, a moisturiser, and not smoking. Most of the rest, including many luxury creams, gold facials and anti-ageing supplements, has far less proof than its marketing suggests.

The anti-ageing market in India is growing fast, with new serums, gummies and clinic packages every month. This guide sorts what is backed by research from what is mostly hype, so you can spend your money and effort where it counts.

Why does skin age?

DermNet describes two kinds of skin ageing:

• Intrinsic ageing is the natural, genetic process that affects all skin, including areas that are covered. The skin gradually becomes thinner, drier and finely wrinkled.
• Extrinsic ageing is caused by the environment, mainly ultraviolet (UV) radiation from the sun, along with smoking and pollution. It shows up on sun exposed areas such as the face, neck, hands and forearms as rough texture, deeper wrinkles and uneven pigmentation.

The good news is that extrinsic ageing is largely preventable. In a country with strong sun for most of the year, sun protection is the most important anti-ageing step you can take. In Indian skin, uneven pigmentation, dark spots and dullness are often more noticeable early signs than deep wrinkles.

What is the evidence for sunscreen?

Sunscreen has the best evidence of any anti-ageing product. In a randomised trial published in the Annals of Internal Medicine, researchers in Australia followed 903 adults under 55 for about four and a half years. People asked to apply broad spectrum sunscreen every day showed no detectable increase in skin ageing, and overall skin ageing was 24 percent less than in the group who used sunscreen only when they chose to.

Practical points for India:

• Use a broad spectrum sunscreen with SPF 30 or higher every morning, including cloudy and monsoon days.
• Apply enough to cover the face, neck and ears, and reapply when you are outdoors for long periods.
• Add shade, hats, umbrellas and sleeves when the sun is strong.

Do retinoids really work for ageing skin?

Retinoids are vitamin A based ingredients and among the best studied anti-ageing topicals. The American Academy of Dermatology explains that they speed up skin cell turnover and stimulate collagen, which helps reduce fine lines, wrinkles and uneven tone. Tretinoin, a prescription retinoid, has decades of research behind it, while retinol is a milder over the counter form.

Points to keep in mind:

• Start slowly. Retinoids commonly cause dryness, peeling and irritation in the first weeks.
• Use at night and apply sunscreen every morning, because retinoids increase sun sensitivity.
• Watch for dark patches. The Academy notes that people with darker skin should watch for hyperpigmentation from irritation, and suggests starting slowly with a moisturiser.
• Avoid in pregnancy. Retinoids should not be used if you are pregnant.

Your dermatologist may prescribe a stronger retinoid if it suits your skin. Our beginner’s guide to retinol and tretinoin walks through how to start.

Does moisturiser help with wrinkles?

A moisturiser will not reverse ageing, but it helps the skin look and feel better. The American Academy of Dermatology notes that a moisturiser can plump up fine lines within a few days by trapping water in the skin. Moisturiser also reduces the dryness and irritation that retinoids can cause, which helps you stick with them.

What lifestyle habits matter most?

The American Academy of Dermatology and DermNet both emphasise habits that cost little:

• Do not smoke. Smoking narrows blood vessels and increases enzymes that break down collagen and elastin.
• Avoid tanning, whether from the sun or tanning beds.
• Eat plenty of vegetables, fruit and fish. DermNet notes that diets rich in vegetables, olive oil and fish are linked with better resistance to sun related ageing.
• Sleep well and cleanse gently, avoiding harsh scrubbing.

Which other ingredients have reasonable evidence?

DermNet lists vitamin C products and alpha hydroxy acids, such as glycolic acid, among cosmetic options for ageing skin. These can help brightness and texture for some people, but they are supporting players rather than replacements for sunscreen and a retinoid. Our guide to vitamin C and niacinamide serums explains how to choose them, and our article on ingredients not to mix helps avoid irritation.

Is it ever too late to start?

No. The sunscreen trial included adults up to the age of 55, and the benefit of daily sunscreen was seen in middle aged participants too, which is why the American College of Physicians summarised the finding as daily sunscreen slowing skin ageing even in middle age. Starting a retinoid, moisturising regularly and stopping smoking can also help at any age.

What changes with age is mainly how gentle you need to be. The American Academy of Dermatology notes that skin becomes drier over time, so richer moisturisers and milder cleansers often suit older skin better. If you are in your 30s, our guide to skin care after 30 suggests a simple starting routine.

What is mostly hype?

Be cautious about:

• Very expensive creams sold on rare or luxury ingredients such as gold, caviar, plant stem cells or snail extracts. Price and exotic ingredients do not tell you whether a product works.
• Products promising instant or permanent results. The American Academy of Dermatology notes that most products take at least six weeks, and sometimes three months, to show results.
• Ten step routines. Using many anti-ageing products at once is more likely to irritate the skin, and irritated skin can look older.
• Gold and diamond facials and similar salon treatments, which may feel pleasant but are not a substitute for evidence based care.
• Anti-ageing supplements. In the sunscreen trial, beta carotene supplements had no overall effect on skin ageing. Our article on collagen and biotin supplements looks at the evidence in detail.
• Do it yourself devices bought online. The Academy warns against DIY cosmetic procedures and counterfeit or illegally imported devices.

How should I use anti-ageing products safely?

The American Academy of Dermatology suggests:

1. Start with one new product at a time.
2. Test it first on a small area, such as the inner forearm, for four to five days.
3. Follow the directions and do not use more than directed.
4. Stop if it stings, burns or causes a rash.
5. Give it at least six weeks before deciding whether it works.

What can a dermatologist offer beyond creams?

The Academy notes that topical products cannot address every sign of ageing. DermNet lists procedures such as chemical peels, laser resurfacing, botulinum toxin and fillers. These should be done by trained doctors in a proper medical setting, after a discussion of risks, especially pigmentation risk in Indian skin. Our guide to Botox and fillers in India covers safety.

When to see a dermatologist

See a dermatologist if:

• You want a personalised, affordable routine and are unsure where to start
• A retinoid or active product keeps irritating your skin
• You have dark patches, melasma or uneven tone that is not improving with sunscreen
• You have a new or changing spot, mole or rough patch on sun exposed skin
• You are considering peels, lasers, Botox or fillers
