If you’re looking for reef-safe sunscreen, look for: OXYBENZONE, OVTINOXATE. There are ingredients that are harmful to the reef. You do not want them in your sunscreen. I have linked sunscreens that I’ve found. I’ve tested the sun bum, coolia and neutrogena in the past and all of them worked great. I recommend checking local guidelines depending on where you’re headed as there might be various brand preferences. For example, I heard someone say that sun bum uses fragrances and chemicals which might affect the reef so just keep it in mind before making a purchase. 🤍 Hope this helps.
