Why are you into it?
This is the one I'd text a friend about.
About
Most sunscreen burns your eyes when you sweat. The kind that doesn't requires zinc oxide or titanium dioxide as the primary active ingredients, not the chemical filters that turn your face into a crime scene when mixed with salt water. Blue Lizard Australian Sunscreen uses zinc oxide at 10% concentration. It goes on thick and white, then disappears. No sting when it runs into your eyes during a three-hour festival set in Tempelhof.
The chemistry is simple. Chemical sunscreens like avobenzone and octinoxate absorb UV rays and convert them to heat. When they mix with sweat, they become irritants. Mineral sunscreens like EltaMD UV Clear sit on top of your skin and reflect light away. They don't break down in heat or salt. They don't migrate into your tear ducts when you're dancing under strobe lights until 6 AM.
Neutrogena Sheer Zinc works for daily wear. Badger Classic Unscented for extended outdoor exposure. Both use zinc oxide as the only active ingredient. The trade-off is application time. Mineral sunscreens require more rubbing to avoid the ghost face effect. But they stay put when you sweat, and your eyes stay clear when the sun hits at 2 PM and you realize you're going to be outside longer than planned.
Fun fact
Zinc oxide was first used as sunscreen by lifeguards in the 1930s, who painted white stripes across their noses like war paint.
