5: Signs your beauty product isn’t doing anything | Krupa Koestline, clean cosmetic chemist 

“I would really hope that we evolve as a sector to get to a point where the consumer doesn’t feel that they need to read the ingredient list to make sure that their product is safe,” says clean cosmetic chemist Krupa Koestline—but in the meantime? There’s a lot to learn. In this episode of Clean Beauty School, mindbodygreen beauty director Alexandra Engler and Koestline discuss how to decode your ingredient list to make sure both it’s safe and effective—with tips like why alcohols aren’t always bad, how to interpret ingredient order, and why she thinks user behavior should influence formulations.
