Is any sunscreen really waterproof?

No. Water-resistant means 40 or 80 minutes.

  1. Yes, if the bottle says waterproof
  2. No, it eventually washes off ✔
  3. Yes, if it says sport or water resistant

Why: FDA says there is no waterproof sunscreen. Water-resistant ones must say if they last 40 or 80 minutes while you swim or sweat.

Huh, didn't know that: After that time, or after towel drying, put more on.
