You already care about what goes on your skin and what ends up in the water. We made something to make that easier.

Meet the Reef-Safer Checker — check any sunscreen, anywhere, in seconds, and know what's really in it before it goes in the ocean.

To start, add our Reef-Safer Checker to your home screen.

Check anything that touches your skin, from sunscreens to lotions to lip balms. Open the link, tap your browser's share menu, and hit "Add to Home Screen." Now it lives right next to your other apps, ready for every beach day, dive trip, or drugstore ingredient-label standoff.

Drop in the ingredient list from whatever's in your bag and we'll tell you straight up whether it can be doing damage every time you get in the water, or whether it's formulated to be safer for aquatic life — like every product we make.

Welcome aboard!
