Sunscreen myths Indians still believe

The short answer

Most common sunscreen myths in India are about skin colour, weather and side effects. Brown skin still gets UV damage that shows as tanning, pigmentation and ageing. UV passes through clouds and UVA passes through glass. Used properly, sunscreen has minimal effect on vitamin D. And the right texture does not need to cause pimples. Quantity matters more than SPF.

Key takeaways

  • Dark skin has some natural protection, but not enough to prevent pigmentation and photo-ageing.
  • Up to 80% of UV passes through clouds, so the monsoon is not a break from sunscreen.
  • A higher SPF does not let you stay out longer, and most people apply too little to get the labelled SPF.
  • Sunscreen used normally has minimal effect on vitamin D levels.
  • Acne-prone skin needs a different sunscreen, not no sunscreen.

Myths about skin colour, weather and being indoors

Myth 1: "Indian skin doesn't need sunscreen"

This is the one I hear most. See, what happens is, brown skin does have more melanin, which gives some protection from burning, and the NHS notes darker skin is less likely to develop skin cancer. So the myth is not completely wrong. It is just incomplete.

The damage in Indian skin shows up differently. Instead of sunburn, we get tanning, dark marks after pimples that last months, melasma and uneven tone. The Indian Sunscreen Forum's 2025 consensus notes that pigmentation after inflammation is more common in skin types IV to VI, and visible-light pigmentation lasts longer in darker skin. The Skin Cancer Foundation says tanning damages all skin types.

So the question is not "do I burn?" It is "do I want more pigment?"

Myth 2: "It's cloudy, I don't need sunscreen"

In the Mumbai monsoon, people put sunscreen away for four months. The American Academy of Dermatology says up to 80% of harmful UV rays can pass through clouds. You may not feel the heat, but the UV is still reaching your skin.

If you are outdoors in the monsoon, keep your sunscreen on. A water-resistant formula helps with rain and humidity.

Myth 3: "I'm indoors all day, so no sunscreen"

It depends on where you sit. The American Academy of Dermatology notes UVA passes through window glass, while UVB is mostly blocked. UVA is the type linked to tanning, pigmentation and ageing.

  • If you sit near a window, at home or at work, or drive a lot, wear sunscreen.
  • If you have melasma, the Indian Sunscreen Forum's consensus advises sunscreen indoors too.
  • If you are deep inside a building with no windows, the need is lower, but a morning application is still a sensible habit.

Myths about SPF numbers and makeup

Myth 4: "SPF 50 means I can stay out longer"

The American Academy of Dermatology is clear that a high SPF does not extend your time outdoors safely. SPF 30 blocks about 97% of UVB, and higher numbers block only slightly more.

That is very important to understand: the number on the bottle assumes you apply 2 mg per square centimetre. Most people apply far less, which reduces real protection a lot. A higher SPF partly compensates for under-application, which is why I often suggest SPF 50 for melasma or heavy outdoor exposure. But it is not a licence to stay in the sun.

My guide to sunscreen for Indian skin explains how much to use.

Myth 5: "My makeup has SPF, that's enough"

The American Academy of Dermatology notes that people rarely apply enough foundation or moisturiser to get the SPF on the label, and that it still needs reapplying when outdoors. Apply sunscreen first, then makeup. A tinted sunscreen can be a good compromise.

Myths about side effects and safety

Myth 6: "Sunscreen causes vitamin D deficiency"

Vitamin D deficiency is common in India, and people worry that sunscreen makes it worse. The Indian Sunscreen Forum's 2025 consensus concludes that sunscreen has minimal impact on vitamin D levels when used according to public health guidance, and cites two Australian randomised trials that found no difference in vitamin D between daily sunscreen users and others.

The American Academy of Dermatology suggests getting vitamin D from foods and fortified products, and speaking to a doctor if you are concerned. A blood test and a supplement, if needed, are a better plan than skipping sunscreen.

Myth 7: "Sunscreen gives me pimples"

Some sunscreens can block pores, especially heavy, greasy ones in humid weather. But that is a texture problem.

  • For oily or acne-prone skin, the Indian Sunscreen Forum suggests non-comedogenic gels, water-based lotions or dry-touch formulas.
  • Wash sunscreen off properly at night with a gentle cleanser.
  • If you still break out, change the product, not the habit.

For acne-prone skin, skipping sunscreen often leads to darker pimple marks. See dark marks after pimples.

Myth 8: "Sunscreen is full of harmful chemicals"

This one deserves a fair answer. The Indian Sunscreen Forum's consensus reviewed common concerns: - Zinc oxide and titanium dioxide nanoparticles do not significantly penetrate the outer skin layer, so systemic harm is unlikely. - Evidence of hormonal effects from oxybenzone in humans is limited and mixed. - In pregnancy, mineral filters are generally considered the safer choice.

If you are worried, a mineral sunscreen is a reasonable option.

Frequently asked questions

Do men need sunscreen?

Yes. Men get the same UV damage: tanning, pigmentation, dark patches on the forehead and cheeks, and earlier wrinkles. Men who ride two-wheelers or work outdoors often have more exposure than women. A light gel sunscreen is easy to use after shaving and does not feel greasy in humid weather.

Is homemade sunscreen safe?

No. Homemade mixtures of oils, aloe or zinc powder cannot be tested for SPF or UVA protection, and they may give a false sense of safety. Some natural oils offer very little protection. Use a commercially tested, broad-spectrum sunscreen of SPF 30 or more, ideally with a high PA rating.

Does sunscreen expire?

Yes. The American Academy of Dermatology notes that sunscreens are required to keep their strength for at least three years, and advises discarding products past their expiry date or that have changed colour or consistency. Do not store sunscreen in a hot car or in direct sunlight. If the bottle has no date, write the purchase date on it.

Should I use sunscreen on children?

For babies under six months, the Indian Sunscreen Forum's consensus advises avoiding direct sun rather than using sunscreen. For children over six months, it suggests a broad-spectrum sunscreen of SPF 15 or higher, plus shade, hats and clothing. Mineral sunscreens are often easier on young skin.
