Sunscreen is probably the best anti-aging product you own.

Yes, as long as you’re using it right.

Sunburn is acute damage. Skin aging from the sun — wrinkles, spots, leathery texture — is cumulative damage. Both come from UV radiation, just on different time scales. SPF blocks enough UV to slow both.

But here’s the rub: you need broad spectrum (UVA + UVB protection), SPF 30+, and you need to actually apply enough. Most people use about half what they should. And reapplying matters more than the number on the bottle — SPF 100 doesn’t help if it wore off four hours ago.

Mineral sunscreens (zinc oxide, titanium dioxide) are more stable and less likely to irritate. Chemical ones work fine if you don’t have a reaction. Either is better than tanning.

The real anti-aging hack isn’t a fancy serum. It’s not skipping sunscreen on cloudy days, or when you’re just driving to work. Glass doesn’t block UVA, which is the main culprit for aging.

Your future self will thank you. Probably.
