Protect our oceans and reefs! Please choose a mineral based sunscreen as there has been research suggesting that four common sunscreen chemicals are toxic to coral health. Unfortunately, 25 to 60 million bottles worth of sunscreen chemicals wash into the coral reef each year. Titanium oxide and zinc oxide (ingredients in natural mineral sunscreens) have not been found to be harmful to coral. Thank you for choosing to shop our mineral based sunscreens!
