Sunscreen is an essential skincare product, especially for Indian skin, which faces unique challenges due to its melanin content and sensitivity to sun-induced pigmentation. However, many myths and misconceptions surround sunscreen usage, leading to confusion and improper protection against harmful UV rays. Two experienced dermatologists, Dr. Achel Pant and Dr. Shivangi, clarify these doubts and provide actionable advice tailored for Indian skin.

Why Sunscreens Are Crucial for Indian Skin

Protecting Against UVA and UVB Rays

Sunscreens guard the skin by blocking or absorbing ultraviolet (UV) rays from the sun. It’s important to understand that there are two key types of rays:

• UVB Rays: Cause sunburn and can be blocked easily when indoors.
• UVA Rays: Penetrate deeper, passing through windows and car glass, and contribute to aging and skin damage.

Dr. Shivangi explains that UVA rays are omnipresent and the primary reason sunscreen is indispensable, even when indoors.

The Unique Concern: Hyperpigmentation in Indian Skin

Unlike Caucasian skin, where wrinkles are the most apparent sign of aging, Indian skin primarily shows sun damage through hyperpigmentation—dark spots and uneven skin tone caused by inflammation or injury like acne or dryness. Therefore, regular sunscreen use is pivotal not just for anti-aging but for maintaining even skin tone and brightness.

Understanding Sunscreen Labels: SPF and PA Values

What Is SPF?

SPF, or Sun Protection Factor, quantifies protection against UVB rays. For example:

• SPF 30 blocks approximately 97% UVB rays.
• SPF 50 blocks around 98%.

Hence, while SPF 50 offers marginally better protection than SPF 30, the difference is not dramatic. SPF does not measure UVA protection.

What Is PA Value?

PA rating represents protection from UVA rays and is tested in vitro (in the lab). Sunscreens are graded with plus signs (+), with more pluses indicating stronger UVA protection.

Indian skin requires attention to both SPF and PA, as UVA rays contribute significantly to pigmentation and premature aging.

Proper Sunscreen Application: Dosage and Timing

How Much Sunscreen Should You Use?

For effective protection, dermatologists agree on applying a two to three finger-length amount of sunscreen to cover the face and neck. The exact amount may vary depending on the sunscreen's nozzle size, but the goal is to create a thin, even film on the skin.

When and How Often to Apply?

• Daily application every morning, regardless of whether you plan to go outdoors. UVA rays penetrate indoor environments like offices or homes.
• Reapply every 2-3 hours if you are outside or exposed to direct sunlight for prolonged periods.
• If indoors and away from windows, you may stretch the application up to 4-5 hours.

Sunscreen Use with Makeup: Best Practices

For those who wear makeup, reapplying sunscreen can be tricky. The dermatologists recommend:

• Gently dab sunscreen onto your face without rubbing to avoid disturbing makeup.
• Set the skin with powder if necessary to reduce shine.
• For reapplication during the day, apply a fresh sunscreen layer before adding concealer or additional makeup.

Remember, sunscreen should always be the final step of your skincare routine, after moisturizer and before makeup.

Common Sunscreen Myths Debunked

1. “Applying sunscreen once is enough for the whole day.”

False. Sunscreens lose effectiveness over time, sweat, and physical activity. Reapplication every 2-3 hours is necessary, especially outdoors.

2. “Sunscreens cause Vitamin D deficiency.”

This is misinformation. Sunscreen usage does not prevent your body’s Vitamin D production completely, as small UVA and UVB exposure, dietary intake, and supplements meet Vitamin D requirements.

3. “People with darker skin tones don’t need sunscreen.”

Incorrect. While darker skin has more melanin, which provides some natural protection, Indian skin is prone to pigmentation and uneven tone caused by sun exposure, making sunscreen vital.

Final Thoughts: Choosing the Right Sunscreen for Indian Skin

For Indian skin, the ideal sunscreen should have:

• A balanced SPF of 30-50 to block UVB rays.
• High PA rating (++++) to combat UVA rays effectively.
• A texture suitable for Indian weather and skin type (non-greasy, gel-based or light lotion for humid climates).

Using the right sunscreen can dramatically reduce premature dark spots, dullness, and the first signs of aging. Incorporate sunscreen as a non-negotiable part of your daily skincare routine to maintain healthy, radiant skin.
