From collagen powders to $100 creams, the skincare industry thrives on promises. However, many of the products we rely on for younger, healthier skin are built on shaky evidence. In this episode, world-renowned dermatologist Professor John McGrath breaks down what’s real and what’s not. We explore how skin truly ages, what happens beneath the surface, and why some popular treatments don’t do what they claim. John dismantles three of the biggest myths in skincare, including the truth about SPF, collagen, and “bio-active” ingredients that never make it past the top layer of your skin. Professor McGrath is a Professor of Molecular Dermatology at King’s College London and editor of the British Journal of Dermatology. His research has transformed how we understand genetic skin disorders and vitamin D’s role in skin health. This conversation is packed with surprising insights - and one daily step that really does support healthier skin as you age. 🥑 Make smarter food choices.
