At Dr. Su, we believe that beautiful skin begins with intelligent protection. Sunscreen isn't just another product; it's the cornerstone of a healthy, glowing complexion, especially when navigating the diverse climate and lifestyles across India. With so many options available, choosing the right sunscreen can feel overwhelming. That’s why our experts have broken it down for you in this simple, science-backed guide, so you can find the formula that truly works for your skin.
What Is Sunscreen And Why It's Essential
Think of sunscreen as your skin's daily shield. Its primary role is to protect your skin from the sun's harmful ultraviolet (UV) radiation. This protection is not just about preventing sunburn; it's about safeguarding your skin's long-term health and appearance.
Why Is Daily Sunscreen Non-Negotiable?
UV rays are the biggest preventable cause of skin ageing and pigmentation, including concerns like fine lines, wrinkles, uneven skin tone, and dark spots. Prevention is easier, more effective, and often cheaper than reversing damage later.
Sunscreen allows your other skincare products, especially those targeting acne or pigmentation, to work more effectively. Without it, you're swimming against the current. This is especially true if you use active ingredients like AHAs (glycolic or lactic acid), which make your skin more sensitive to UV.
Australian and WHO guidelines suggest sun protection when the UV index is 3 or above, which is most of the year in India. If you care about texture, tone, and clarity, sunscreen isn’t optional.
Types Of Sunscreen: Physical VS. Chemical
Sunscreens typically fall into two categories:
-
Physical (Mineral): These sunscreens use zinc oxide or titanium dioxide as active ingredients. They sit on the surface of the skin and primarily reflect and scatter UV rays, though they also absorb some UV.
- Chemical: Use organic compounds that absorb UV radiation and convert it into harmless heat.
What Should You Choose?
-
Sensitive skin: Try physical sunscreens.
-
Hate white cast or thick textures: Opt for modern chemical sunscreens.
-
Need a balance: Use hybrid formulations with both types.
The bottom line: It’s not about the type, it’s about comfort, tolerance, and wearing it every day.
Understanding SPF and UVA Protection Ratings
SPF (Sun Protection Factor)
SPF measures protection against UVB rays (burning rays). SPF 30 blocks ~97% of UVB, while SPF 50 blocks ~98%. Don’t worry about tiny % differences, just make sure you're applying enough.
UVA Protection
UVA rays penetrate deeper, contributing to ageing and pigmentation. Look for:
-
"Broad Spectrum" label
-
PA+++ or higher
Water Resistance
-
“Water-resistant”: Lasts 40 minutes in water
-
“Very water-resistant”: Lasts 80 minutes
This also indicates sweat and rub resistance, essential in Indian weather.
Choosing Sunscreen By Skin Type & Concern
Texture Matters
If it feels bad, you won’t use enough. Lightweight, gel-based, or serum-like formulas encourage consistent use.
Oily Skin
Choose matte-finish or gel-based formulas. Patting on translucent powder can reduce shine.
Sensitive Skin
Try fragrance-free physical sunscreens. Always patch test.
Hyperpigmentation (especially deeper skin tones)
Go for tinted sunscreens with iron oxides for visible light protection.
Acne-Prone Skin
Look for non-comedogenic formulas. Start with one type, test, and avoid layering multiple actives.

Sunscreen Myth-Busting Speedrun
-
“SPF 50 is only 1% better than SPF 30” – Myth! The difference in burn protection may seem small, but high SPF helps account for under-application.
-
“Chemical sunscreens cause hormone issues” – Legal UV filters have large safety margins.
-
“Sunscreen causes vitamin D deficiency” – Myth! Moderate sun exposure still allows for vitamin D synthesis.
-
“Sunscreens need time to activate” – No, but they need time to settle like paint.
- “DIY sunscreen works” – Never. It’s unreliable and unsafe.
