Do We Really Need Sunscreen in India? Let’s Separate Science from Social-Media Fear

In India, skincare advice rarely remains simple.

Someone says, “Use sunscreen every day,” and almost immediately another reel appears saying:

“Sunscreen is unnecessary.”
“Your body needs the sun to make vitamin D.”
“Sunscreen blocks vitamin D.”
“Chemical sunscreens enter your bloodstream.”
Or the most frightening one: “Sunscreen causes cancer.”

When these statements are repeated confidently by influencers and people with no relevant scientific or medical training, it is understandable that consumers become confused.

So let us start with the question that should come before choosing a sunscreen:

Do we actually need sunscreen?

Yes - but we also need to understand why.

The sun is not inherently bad for us. Sunlight plays an important role in our biological rhythms, and UVB exposure to the skin can initiate vitamin D synthesis.

But that does not mean that deliberately exposing unprotected skin to ultraviolet radiation is the best or safest way to maintain vitamin D.

Ultraviolet radiation can damage skin cells, accelerate skin ageing and contribute to skin cancer. This applies to people of every skin colour, although natural melanin provides darker skin with some additional protection.

That distinction is important:

We need vitamin D. We do not need unnecessary UV damage in order to obtain it.

But doesn't sunscreen stop vitamin D production?

This argument contains a little science and a lot of oversimplification.

UVB radiation is involved in vitamin D production, and a sunscreen can reduce the amount of UVB reaching the skin. But laboratory theory and what happens in real life are not necessarily the same thing.

Interestingly, an Indian study followed people with melasma who used SPF 50+ PA++++ sunscreen on their faces for three months, together with physical sun protection. Researchers found no significant change in their serum vitamin-D concentration. The study was relatively small, so it should not be treated as the final word on the subject, but it is particularly relevant when discussing sunscreen use under Indian conditions.

The American Academy of Dermatology recommends obtaining adequate vitamin D through diet, fortified foods and, when medically necessary, supplementation rather than deliberately increasing unprotected UV exposure.

If vitamin-D deficiency is a concern, test it and discuss it with your doctor. Removing sunscreen is not a treatment for vitamin-D deficiency.

Does sunscreen cause cancer?

This is one of the most irresponsible claims circulating online.

There is currently no good evidence that properly formulated, regulated sunscreens used as directed cause cancer.

What we do know is that ultraviolet radiation damages the skin and can contribute to skin cancer.

Some studies have shown that certain organic sunscreen filters can be absorbed through the skin and detected in the bloodstream. This finding has often been turned into frightening social-media headlines.

But absorption does not automatically mean toxicity, and it certainly does not automatically mean cancer.

The FDA itself has specifically explained that detecting an ingredient in the bloodstream does not establish that the ingredient is unsafe; it indicates that further safety data may be required.

Science should investigate sunscreen ingredients. Formulations should continue to improve. Regulations should evolve as new evidence emerges.

But questioning an ingredient scientifically is very different from announcing on a reel that “sunscreen causes cancer.”

Indian skin needs a slightly different conversation

For many Indian consumers, sun protection is not only about preventing sunburn.

Our bigger everyday concerns often include:

tanning, uneven skin tone, melasma, post-inflammatory pigmentation and premature ageing.

Melasma and post-inflammatory hyperpigmentation are aggravated not only by ultraviolet radiation but, in susceptible darker skin types, by visible light as well. Research has shown that sunscreens containing pigments such as iron oxides can provide additional protection against visible-light-induced pigmentation.

This is why someone struggling with pigmentation may benefit from a tinted broad-spectrum sunscreen containing iron oxides, rather than choosing solely according to the SPF number.

And this brings us to the next problem.

Once you decide to use sunscreen, which one should you buy?

Do not buy sunscreen simply because somebody says, “This is the best sunscreen in India.”

The best sunscreen is one that provides adequate protection, suits your skin and—most importantly—is comfortable enough for you to use properly.

Look for:

• Broad-spectrum protection against both UVA and UVB.

• SPF 30 or above. SPF 50 is a sensible choice when sun exposure is significant, particularly in Indian conditions.

• Good UVA protection—for example, PA++++ where that rating system is used.

• Water resistance if you sweat heavily, exercise, swim or spend significant time outdoors.

• Tinted/iron-oxide-containing sunscreen when melasma or stubborn pigmentation is a major concern.

Do not become obsessed with whether a sunscreen is labelled “mineral” or “chemical.”

Both types can provide effective protection when properly formulated and tested. A beautiful ingredient list means very little if the finished product does not provide reliable protection—or if you dislike it so much that you never apply enough.

And how should you actually use it?

This is where many people who say “sunscreen didn't work for me” go wrong.

Apply an adequate amount to exposed skin before going outdoors. When you remain outdoors, sunscreen should generally be reapplied approximately every two hours and after heavy sweating, swimming or towel drying. Sunscreen should also be combined with shade, sunglasses, hats and protective clothing rather than being treated as an invisible shield that allows unlimited sun exposure.

And no—you do not have to live in fear of the sun.

Sun protection is about managing excessive exposure, not avoiding normal life.

What will you actually gain from using sunscreen consistently?

Perhaps this is the part we should speak about more often.

Consistent, sensible photoprotection can help:

reduce sunburn and tanning, limit cumulative UV damage, slow premature photoageing, protect collagen from unnecessary environmental damage and support the management of conditions such as melasma and post-inflammatory pigmentation.

And if you are spending money on vitamin C, retinoids, exfoliating acids, pigmentation serums and professional skin treatments while repeatedly exposing your skin to unprotected sunlight, you are making those treatments work considerably harder.

My final thought

Sunscreen is not anti-sun. It is anti-unnecessary skin damage.

Yes, ask questions about sunscreen.
Yes, read ingredient lists.
Yes, expect manufacturers to demonstrate safety and efficacy.

But also ask questions about the information you consume.

Who is saying it?
What are their qualifications?
Where is the evidence?
And are they explaining the complete science—or simply giving you a frightening sentence that performs well in a 30-second reel?

Your skin does not need fear.

It needs informed choices.
