Sunscreen Is Not Optional — Here Is Why

If I could give every client one piece of advice and nothing else, it would be this: wear sunscreen every day. Not on beach days. Not when you are going outside for long periods. Every day, indoors and out, regardless of the weather.

I have seen more long-term skin damage from skipped sunscreen than from any other single skincare mistake. And in India, where UV index levels are among the highest in the world year-round, the stakes are higher than most women realise.

The myths stopping Indian women from using SPF.

The most common thing I hear: "I have dark skin, I do not need sunscreen." This is a myth that has caused genuine harm. While melanin does provide some natural protection, it is nowhere near enough to prevent UV damage, hyperpigmentation, or premature aging. In fact, darker skin tones are more prone to post-inflammatory hyperpigmentation — the dark marks left behind by sun exposure, acne, and inflammation. Sunscreen is not less important for Indian skin. It is more important.

The second myth: "I am indoors most of the day." UV radiation penetrates windows. Blue light from screens accelerates pigmentation and collagen breakdown. If you are sitting near a window or spending hours on a laptop or phone, you are being exposed. The indoors-equals-safe logic does not hold.

What 80% means.

Research consistently shows that 80% of visible skin aging — fine lines, pigmentation, loss of elasticity — is caused by UV exposure, not chronological aging. This is the statistic I share with every client who tells me they will start wearing sunscreen when they are older. The damage is happening now. It shows up later.

This also means that the most effective anti-aging investment available is not a retinol serum or a vitamin C treatment — it is a broad-spectrum SPF 50 worn consistently every day from your twenties onward. No product I can recommend undoes UV damage. Prevention is the only strategy that works.

How to actually wear it correctly.

Most women use far too little. The standard recommendation is a teaspoon for the face and neck — more than most people apply. If you are using sunscreen as the last step of your routine and applying a thin layer, you are getting a fraction of the labelled SPF protection.

Reapplication matters too. Sunscreen degrades with UV exposure, sweat, and contact. If you are outdoors for extended periods, reapply every two hours. If you are indoors and relatively stationary, once in the morning is usually sufficient.

For Indian skin, I generally recommend lightweight, non-comedogenic formulas — either chemical sunscreens with no white cast or mineral-chemical hybrid formulas. The era of sunscreens that leave a grey tint on brown skin is over. There are excellent Indian-climate-appropriate options at every price point.

The one non-negotiable.

You can skip serums. You can simplify your routine to three steps. But sunscreen stays. Every single day. It is the foundation that everything else is built on — and without it, most of what else you are doing for your skin is working against the clock.
