@bookpinch: Do you think you know a lot about sun protection? Does SPF 30 mean double the protection of SPF 15? Do you still need sunscreen on a cloudy day? Can you skip reapplying if your makeup has SPF in it? Does a higher number mean you’re covered all day? If you got any of those wrong, you’re not alone. Understanding sunscreen and sun damage isn’t optional. It’s essential to keeping your skin healthy long term. #spf #sunprotection #sundamagedskin #selfcareroutine #pinchmed
