Are clean beauty products better for the environment? Who still tests on animals and why? How do retailers and brands develop their lists of restricted substances (aka, “no no” lists)? In honor of Earth Day, cosmetic biochemist Krupa Koestline—founder of KKT Consultants, a product-development firm—is here to answer all your questions. We’ll discuss the current state of “clean” beauty and dig into some more complicated issues, like the potential dangers of ethoxylated ingredients, how and why fragrances are used in product formulation, which skincare ingredients are overrated, and more.

Below you’ll find a list of some of the people, topics, and products mentioned in this episode. If you have any questions (or just want to say hi), reach out to us on Instagram or via email (info@fatmascara.com). And please email us voice memos of your beauty questions and Raise A Wand favorites so we can share them on the show.
