Sunscreen Is the Most Boring Anti-Aging Product That Actually Works

Dermatologists will tell you the single most effective thing you can do for your skin is wear sunscreen daily. Not the expensive serum. Not the trendy supplement. SPF 30 or higher, applied every morning, even on cloudy days. UV damage is cumulative — it adds up silently over years and shows up as wrinkles, spots, and increased skin cancer risk. Reapply every two hours if you're outside. It's unglamorous advice, but the evidence behind it is overwhelming.
