What's In Your Stage Makeup?

Ballet dancers layer on a cringe-worthy amount of makeup for performance—pancake, lipstick, eyelash glue—but most probably don't think twice about the chemicals in the products they're using. Environmental Working Group's Skin Deep Database allows you to search most major cosmetic and bath products, and alerts you when they include ingredients that have been known to cause cancer, skin irritation, allergies and more. Overwhelmed? The site also gives you some guidelines to shop by.
