Why Sunscreen Matters
Sunscreen is a dermatologist’s top recommendation for healthy skin.
Despite limited coverage in dermatology textbooks, it remains the most common question patients ask: “Which sunscreen should I use?”
Choosing sunscreen is more than picking a bottle—it depends on skin tone, climate, and lifestyle.
Types of Sunscreens
Physical (Mineral) Sunscreens
Contain zinc oxide or titanium dioxide.
It sits on the skin and reflects UV rays.
Work immediately; ideal for sensitive or oily skin, or conditions like rosacea.
Chemical Sunscreens
Absorb UV rays and convert them to heat.
Often lighter and less visible on the skin.
Understanding Ratings
SPF (Sun Protection Factor): Protects against UVB rays (prevents sunburn).
PA Rating: Protects against UVA rays (prevents aging and pigmentation).
Recommendation for India: SPF 30+ with PA+++ for daily use.
Matching Sunscreen to Skin Tone
Fair Skin: SPF 50+ for higher sensitivity.
Medium/Olive Skin: SPF 30–50 for balanced protection.
Darker Skin: SPF 30–40 in clear or gel formulas to avoid white cast; melanin offers some protection but not complete defense against sun damage.
Choosing Sunscreen for Climate
Humid Regions (North-East, South India): Gel-based, mattifying sunscreens prevent heaviness and stickiness.
Dry Regions (Delhi, Rajasthan): Creams with hydrating ingredients prevent flakiness.
High Altitudes (Mountains): Stronger UV exposure; SPF 50+ is recommended.
Key Takeaways
Skin tone and local climate influence sunscreen choice.
Apply sunscreen generously and reapply consistently.
Whether fair or dark, humid or dry, the right sunscreen protects, nourishes, and keeps skin healthy.
