Your “SPF 100” sunscreen may not be as protective as it claims. According to Environmental Working Group’s 2015 Guide to Sunscreen, SPF protection tops out at 30 to 50. And just because you’re not getting burnt doesn’t mean you’re not damaging your skin: High SPF is able to suppress a sunburn while allowing in dangerous UV rays. In fact, the FDA is considering a ban of SPF above 50+. The EWG also recommend skipping spray sunscreen, which can be inhaled and don’t cover skin completely. For ideal protection, reapply a golfball-sized dollop of lotion every two hours as instructed.
