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

For most people in India, the best sunscreen is a broad spectrum product with SPF 30 to 50 and a PA rating of PA+++ or PA++++, applied generously every morning and reapplied every 2 hours when you are outdoors. The exact brand matters much less than choosing a texture you like enough to wear every single day.

India sits close to the equator, and for much of the year the UV index in most cities is high to extreme by midday. On brown skin the visible damage is usually not sunburn. It is tanning, uneven tone, melasma, and acne marks that refuse to fade. Sunscreen is one of the few skincare steps with strong evidence behind it, and it supports almost every other treatment your dermatologist may recommend.

What do SPF and PA actually mean?

Sunlight contains two main types of ultraviolet radiation that affect skin.

• UVB causes sunburn and contributes to skin cancer. SPF (sun protection factor) measures protection against UVB.
• UVA penetrates deeper, passes through window glass, and drives tanning, pigmentation and skin ageing. The PA rating, used widely in Asian markets including India, describes UVA protection.

PA ratings run from PA+ to PA++++. More plus signs mean more UVA protection. Because UVA is a major driver of tanning and melasma in Indian skin, the PA rating deserves as much attention as the SPF number. If a product does not show a PA rating, look for the words broad spectrum, which indicate it has been tested for both UVA and UVB.

Label	What it tells you	What to look for in India
SPF 15	Basic UVB protection	Too low for Indian summers
SPF 30	Filters about 97 percent of UVB	Good minimum for daily use
SPF 50	Filters about 98 percent of UVB	Useful for long outdoor time, melasma
PA++	Moderate UVA protection	Usually not enough for pigmentation
PA+++	High UVA protection	Good daily choice
PA++++	Very high UVA protection	Best for melasma and tanning prone skin

Is a higher SPF always better?

Not really. The jump from SPF 30 to SPF 50 is small, and anything above 50 adds very little in practice. The bigger problem is that almost everyone applies too little. SPF values are measured using a thick layer of product, and a thin smear can give you a fraction of the protection printed on the bottle. A properly applied SPF 30 beats a barely there SPF 100.

How much sunscreen should I apply?

A practical guide for the face and neck is roughly two finger lengths of a lotion or cream, squeezed along your index and middle fingers. For the whole body, the NHS suggests around 2 teaspoons to cover the head, arms and neck, and about 2 tablespoons if you are covering most of your body.

A few habits help:

1. Apply sunscreen as the last step of your morning routine, after moisturiser.
2. Wait a few minutes before makeup so it settles.
3. Do not forget the ears, sides of the neck, back of the hands and the hairline parting.
4. Use a lip balm with SPF if you spend time outdoors.

How often should I reapply in Indian summers?

Reapply every 2 hours when you are outdoors, and straight away after heavy sweating, swimming or towel drying. In May and June, a commute on a two wheeler or a walk to the market at noon is enough to warrant reapplication.

If reapplying over makeup feels impossible, options include a sunscreen stick, a sunscreen powder, or a spray used as a top up over a properly applied morning layer. Sprays and powders are hard to apply in an adequate amount, so they work best as top ups rather than your only protection.

If you work indoors away from windows, a generous morning layer may be enough on most days. If you sit by a sunny window or drive a lot, reapply at lunch.

Mineral or chemical sunscreen: which is better for brown skin?

Both can protect well. The choice depends on your skin, your tolerance and how the product looks on you.

Type	Filters	Pros	Cons on Indian skin
Mineral (physical)	Zinc oxide, titanium dioxide	Gentle, good for sensitive and rosacea prone skin	Can leave a white or grey cast
Chemical (organic)	Various UV absorbing filters	Light, invisible, comfortable in humidity	Occasional stinging or sensitivity
Tinted mineral	Mineral filters plus iron oxides	Blends better, also blocks some visible light	Shade matching can be tricky
Hybrid	Mix of both	Balance of feel and protection	Varies by formulation

White cast is a real reason many Indians stop using sunscreen. If a mineral sunscreen looks chalky on you, try a tinted version close to your skin tone, or a lightweight chemical or hybrid formula. Tinted sunscreens containing iron oxides also offer some protection against visible light, which matters for people with melasma and pigmentation. You can read more in our guide to melasma on Indian skin.

Which texture works for my skin type?

• Oily or acne prone skin: gels, fluids and matte finish lotions labelled non comedogenic. These sit well in humid weather.
• Dry skin: creams or lotions with added moisturising ingredients, especially in North Indian winters.
• Sensitive or rosacea prone skin: fragrance free mineral or gentle hybrid formulas.
• Very sweaty days or sport: water resistant sunscreen, reapplied after sweating.

Does sunscreen stop vitamin D production?

In everyday use, people rarely apply enough sunscreen, consistently enough, to fully block vitamin D production. Vitamin D deficiency is common in India for many reasons, including diet and indoor lifestyles. If you are concerned, ask your doctor about testing rather than skipping sunscreen.

What else protects skin besides sunscreen?

Sunscreen works best as one layer of a wider plan. WHO advises extra care when the UV index is 3 or higher, which in much of India is most days of the year.

• Seek shade between about 10 am and 4 pm when the sun is strongest.
• Wear a wide brimmed hat or carry an umbrella. A dupatta or scarf over the head and neck helps on two wheelers.
• Choose sunglasses that block UV.
• Wear loose, tightly woven clothing that covers the arms on long outdoor days.
• Remember that UV reflects off water, sand and concrete, and reaches you through light cloud cover.

Common sunscreen mistakes

• Using sunscreen only on sunny days or only outdoors.
• Applying a pea sized amount for the whole face.
• Relying only on SPF in foundation or compact.
• Applying once in the morning and never again during a long outdoor day.
• Using last year’s opened bottle that has been sitting in a hot car or bag.
• Mixing sunscreen with other creams, which dilutes it.

Is sunscreen safe for children and during pregnancy?

Babies under 6 months should be kept out of direct sun and protected with clothing and shade rather than sunscreen, unless a doctor advises otherwise. For older children, mineral sunscreens are a gentle choice. During pregnancy, sunscreen is especially helpful because melasma often appears or worsens, and many women prefer mineral formulas. Our guide to skin changes in pregnancy covers this in more detail.

When to see a dermatologist

See a dermatologist if you:

• Develop dark patches on the cheeks, forehead or upper lip that keep spreading despite sunscreen.
• Get a rash, itching or burning after sun exposure, or after applying a particular sunscreen.
• Notice a mole or spot that is changing in size, shape or colour, bleeds, or does not heal.
• Take medicines that make you sun sensitive and are unsure how to protect your skin.
• Have tried several sunscreens and cannot find one that works for your skin.
