I chatted with holistic esthetician Lesley Thornton, founder of KLUR, for an episode of Clean Beauty School. Even before we started the episode, I knew we shared a lot of the same opinions about the beauty space we both occupy: That natural and synthetic aren’t mutually exclusive, skin care is deeply personal, and it’s important to find products you actually want to use, and that the skin should serve as our best teacher on how to care for it.
