Unlocks when you sign up

Not all exfoliation works the same way and skin doesn’t always need the same approach. Esthetician Renée Rouleau and cosmetic chemist Valerie George break down how acids and enzymes differ, what each does, and how to think through which approach makes sense based on what the skin needs that day.

Course content is educational and is not medical advice. Exfoliation is not right for every skin, so follow product directions and see a qualified professional about any skin concern.
