Sunscreen is the single most important anti-aging and anti-pigmentation product. Yet most people use it wrong. ## Why Sunscreen Matters UV rays cause: - Premature aging (fine lines, wrinkles) - Pigmentation, melasma, dark spots - Sunburn and tanning - Increased risk of skin cancer ## Understanding SPF and PA - **SPF** — Protection against UVB (burning rays). Choose SPF 30-50. - **PA** — Protection against UVA (aging rays). PA+++ or PA++++ is best. - **Broad Spectrum** — Protects against both UVA and UVB. ## Physical vs Chemical Sunscreen **Physical (Mineral):** - Zinc oxide, Titanium dioxide - Works immediately - Gentle on sensitive skin - Slight white cast (but modern formulas are better) **Chemical:** - Absorbs into skin - No white cast - Better for deeper skin tones - Wait 20 minutes before sun exposure ## Best Sunscreens for Indian Skin Look for: - SPF 50 PA+++ - Non-comedogenic (won't clog pores) - Gel or water-based (less greasy) - Tinted (blends better) - Fragrance-free (if sensitive) ## How to Apply Correctly - Use 2-finger rule (2mg/cm²) - Apply 20 minutes before going out - Reapply every 3-4 hours - Don't forget ears, neck, hands - Reapply after swimming or sweating ## Common Mistakes - Using too little product - Skipping on cloudy days (UV still passes through) - Not reapplying - Relying on makeup SPF alone - Using expired sunscreen ## When to Use Sunscreen Indoors Yes, if you're sitting near a window with sunlight, or using screens for long hours, use sunscreen. Blue light from screens can also cause pigmentation.
