Sunscreen is an indispensable part of daily skincare—but despite its importance, widespread myths and misunderstandings persist, especially concerning Indian skin. Two experienced dermatologists, Dr. Achel Pant and Dr. Shivangi, shed light on why sunscreen matters, how it works, and how to choose the right product for Indian skin types. This article unpacks their expert insights, busts common myths, and offers practical advice tailored to Indian skin.

Why Sunscreens Are Essential for Indian Skin

Unlike the Western emphasis on sunscreen primarily for anti-aging or wrinkle prevention, the needs of Indian skin are different. Dr. Shivangi highlights that the earliest and most notable sign of aging in Indian skin is hyperpigmentation, not wrinkles. This is because Indian skin tends to darken or develop uneven tone following any injury or irritation, including acne, dryness, or sun exposure.

UVA vs UVB Rays: What You Should Know

• UVB rays are mostly blocked indoors and are primarily responsible for sunburn.
• UVA rays, on the other hand, penetrate glass windows in homes, cars, and offices and cause long-term skin damage like pigmentation and premature aging.

Therefore, protection against UVA rays is especially critical for Indian skin, which is more prone to pigmentation issues triggered by sun exposure.

Decoding SPF and PA: The Metrics That Matter

Understanding the labels on sunscreen products can be confusing, especially with rising options like SPF 30, 50, 100, and PA ratings.

What is SPF?

• Sun Protection Factor (SPF) measures protection from UVB rays, the ones that cause sunburn.
• SPF 30 blocks roughly 97% of UVB rays, while SPF 50 blocks about 98%. The difference becomes marginal beyond SPF 50.
• Higher SPF does not mean better all-around protection; it mainly relates to the UVB spectrum.

What is PA?

• PA rating indicates protection against UVA rays.
• It is measured differently—in vitro using spectrophotometers that determine how much UVA radiation passes through the sunscreen film.
• The PA scale uses plus signs (PA+, PA++, PA+++), showing increasing UVA protection.

For Indian skin, where UVA-driven hyperpigmentation is the primary concern, choosing sunscreen with high PA values is as important as SPF.

How and When to Apply Sunscreen for Maximum Benefits

Frequency and Reapplication

Many people believe that applying sunscreen once in the morning is sufficient. Both dermatologists strongly disagree:

• If indoors with minimal sun exposure, sunscreen application can last 4-5 hours.
• If outdoors, sunscreen needs to be reapplied every 2-3 hours to maintain protection, especially against UVA.

This is crucial for everyday activities such as commuting, running errands, or being in offices with glass windows that let in UVA rays.

How Much Sunscreen to Use?

Forget the “pea size” rule. The recommended quantity is:

• About two to three finger-length strips of sunscreen for face and neck.
• This ensures a thin yet complete film over the skin that functions effectively.
• Pay attention to the sunscreen’s nozzle size; a wider nozzle might need less quantity per application.

Layering Sunscreen in Your Routine

• Sunscreen should always be the last step in your morning skincare regimen.
• Start with cleanser, then serums, followed by moisturizer.
• Apply sunscreen on dry, clean skin before makeup.

Makeup and Sunscreen: Can You Reapply Sunscreen on Top of Makeup?

Reapplying sunscreen while wearing makeup can be challenging but is achievable:

• Gently dab sunscreen without rubbing to avoid disturbing makeup.
• If the skin becomes oily, use a setting powder to mattify.
• Alternatively, apply sunscreen and a little concealer only on specific sun-exposed areas.

This keeps your skin protected without compromising your makeup finish.

Common Sunscreen Myths Debunked by Experts

Myth 1: Sunscreens Cause Vitamin D Deficiency

• Fact: Sunscreens do not cause vitamin D deficiency. Normal exposure to sunlight, diet, and supplementation ensure sufficient vitamin D.

Myth 2: One Application a Day is Enough

• Fact: Reapplication is essential, especially if you spend prolonged time outdoors.

Myth 3: Sunscreens Are Only for Fair Skin

• Fact: Sunscreens are crucial for all skin tones; in Indian skin, they prevent pigmentation and early aging signs.

Choosing the Best Sunscreen for Indian Skin

Indian skin benefits most from broad-spectrum sunscreens that offer:

• Protection against both UVA and UVB rays (high SPF and PA+++)
• A formulation suitable for oily, dry, or combination skin types common in India
• Non-comedogenic and lightweight textures for daily wear

Conclusion

Understanding the science behind sunscreens helps Indian consumers make informed choices—debunking myths, emphasizing UVA protection, adopting proper application habits, and selecting suitable formulas. Incorporating sunscreen daily and correctly can dramatically reduce hyperpigmentation, maintain an even skin tone, and delay visible signs of aging unique to Indian skin.

Make sunscreen a non-negotiable ritual every day—and help your skin stay protected, nourished, and radiant all year round.
