The two most commonly used mineral ingredients
, titanium dioxide and zinc oxide are two sunscreen ingredients the FDA has deemed to be generally safe and effective. Not to mention that mineral formulas also have the benefit of being much less irritating, especially if your skin skews towards sensitive.
Mineral sunscreens with “non-nanotized” zinc oxide or titanium dioxide (“non-nanotized” means the ingredients are 100 nanometers in diameter or more) appear to be safer for coral reefs than chemical ones. But, it’s near impossible for consumers to decipher which products meet this bill.
The US federal government
requires sunscreen claims to be “truthful and not misleading,” but the term “reef safe” doesn’t have an agreed-upon definition, and therefore isn’t strictly regulated by government
. This means sunscreen manufacturers aren’t required to test and demonstrate that such products won’t harm aquatic life.
