In this podcast episode, dermatologist and scientist Carter Gottlieb dives into the science of skincare while debunking popular myths. He highlights the crucial role of sunscreen, particularly Korean formulations, and explains the benefits of "slugging" with occlusive moisturizers. Gottlieb also discusses the effectiveness of key active ingredients like retinoids, vitamin C, hyaluronic acid, and niacinamide. Additionally, he touches on how diet and supplements, such as carotenoids, can impact skin health, along with the effectiveness of various treatments, both in-clinic and at home, including lasers, red light therapy, gua sha, and facials. Throughout the conversation, Gottlieb advocates for evidence-based practices, encourages a critical look at research, and promotes a holistic approach to skincare that prioritizes overall skin health over aggressive anti-aging tactics.
