The FDA regulates sunscreen as an over-the-counter drug. Isn’t that interesting? If you want to get nerdy about it: Currently 16 UV filters are listed as approved actives, 14 are organic filters commonly referred to as chemical filters, and 2 are inorganic filters commonly referred to as physical or mineral filters. A mineral sunscreen includes one or both of those two inorganic filters, zinc oxide and titanium dioxide. All UV actives absorb UV rays, but mineral UV actives like Zinc oxide also scatter (reflect) UV rays. This means that mineral UV actives protect you in two ways, like a jacket that is both thick and wind breaking. You’re literally shining, as you should!
