As a PhD chemical engineer, and lifelong surfer, Guerry Grune knows firsthand what's at stake in the sun. After watching a close friend receive a melanoma diagnosis, he set out to engineer a sunscreen he could trust ā one made entirely from food-grade ingredients, free from synthetic chemicals, and safe for the reefs he surfs. That mission became 3rd Rock Essentials.
