Sunscreen Guide: How to Choose the Best SPF for Your Skin
Updated on March 20, 2026 • By Skincity Official
Sunscreen isn’t optional—it’s the most important step in any skincare routine. Whether it’s summer, winter, or monsoon, daily sun protection prevents tanning, pigmentation, premature aging, and even skin cancer. But with so many options available, how do you choose the right one?
What Does SPF Mean?
SPF (Sun Protection Factor) measures how well a sunscreen protects your skin from UVB rays (the ones that cause sunburn).
SPF 30 blocks about 97 percent of UVB rays.
SPF 50 blocks about 98 percent of UVB rays.
Higher SPF offers slightly more protection, but correct application matters more than the number.
Types of Sunscreens
Physical (Mineral) Sunscreen
Contains zinc oxide or titanium dioxide.
Best for: Sensitive or acne-prone skin.
Pros: Works immediately, less irritation.
Chemical Sunscreen
Absorbs UV rays and converts them into heat.
Best for: Daily use, lightweight feel.
Pros: No white cast, easy to blend.
How to Choose the Right Sunscreen for Your Skin Type
Oily skin: Use gel-based or matte finish sunscreen and look for non-comedogenic formulas.
Dry skin: Choose hydrating sunscreens with hyaluronic acid or glycerin.
Sensitive skin: Prefer mineral sunscreen with fewer chemicals.
Pigmentation-prone skin: Use broad-spectrum SPF 50 for maximum protection.

Reapply every 3-4 hours.
Do not forget neck, ears, and hands.
Common Mistakes to Avoid
Skipping sunscreen on cloudy days.
Applying too little product.
