Experimental new sunscreen forgoes minerals, replacing them with plant pollen 🌱. When applied to animal skin in lab tests, it rated SPF 30, blocking 97% UV rays ☀️. It had no effect on corals 🐠, even after 60 days. By contrast, corals died of bleaching within 6 days of exposure to commercial sunscreens 🧴.
