Key takeaways
- Indian skin can still burn, tan, age early and develop pigmentation such as melasma from sun exposure.
- Choose a broad spectrum sunscreen with SPF 30 or higher and PA+++ or PA++++ for UVA protection.
- Most people apply too little: use about two finger lengths for the face and neck and reapply every 2 hours outdoors.
- Gel or lightweight fluid textures suit humid weather and oily skin; mineral formulas suit sensitive skin.
"I'm brown, so I don't need sunscreen" is one of the most common skincare myths in India. Darker skin has more natural protection from melanin, but it isn't complete, and in a country with intense sunshine for much of the year, sun damage is a real concern.
Why Indian skin needs sun protection
Ultraviolet (UV) radiation from the sun causes:
- tanning and uneven skin tone
- pigmentation disorders such as melasma and sun spots, which are especially common in Indian skin
- premature ageing: wrinkles, sagging and rough texture
- sunburn, particularly in fairer skin, at high altitudes and near water or snow
- skin cancer: less common in darker skin but often diagnosed later
UVA vs UVB
- UVB causes sunburn. SPF (sun protection factor) measures protection against UVB.
- UVA penetrates deeper, causes tanning, pigmentation and ageing, and passes through glass and clouds. The PA rating (PA+ to PA++++) measures UVA protection.
Look for "broad spectrum" on the label, meaning it protects against both.
What to look for
- SPF 30 or higher for daily use; SPF 50 for long hours outdoors.
- PA+++ or PA++++.
- Texture for your skin type and climate:
- oily or acne prone skin: gel, fluid or "matte" formulas labelled noncomedogenic
- dry skin: cream or lotion formulas
- sensitive skin or children: mineral (zinc oxide, titanium dioxide) sunscreens
- Water resistance for swimming or sweating, reapplied every 40 to 80 minutes as labelled.
How much to apply
Most people apply only a quarter to half of the amount used in lab tests, which gives much less protection than the label promises.
- Face and neck: about two finger lengths (squeeze a line along your index and middle fingers), or a level half teaspoon.
- Whole body: about a shot glass full (30 ml).
How to apply
- Apply as the last step of your morning skincare, 15 minutes before going out.
- Don't forget ears, neck, back of the hands and the tops of the feet.
- Reapply every 2 hours outdoors, and after swimming, sweating or wiping your face.
- Use a lip balm with SPF.
- Over makeup, use a sunscreen spray, stick or powder to reapply.
Indoors and on cloudy days
UVA passes through windows and clouds. If you sit near a window or drive a lot, daily sunscreen on the face and hands is worthwhile.
Other sun smart habits
- Seek shade between 11 am and 3 pm, when UV is strongest.
- Wear a wide brimmed hat, sunglasses with UV protection and long sleeves.
- Carry an umbrella in the summer.
Does sunscreen cause vitamin D deficiency?
In real life use, sunscreen doesn't appear to cause significant vitamin D deficiency. If you're concerned, read our guide on vitamin D deficiency and speak to your doctor.
When to see a dermatologist
See a dermatologist for a mole that changes in size, shape or colour; a sore that doesn't heal; or patches of pigmentation that are spreading.
