Hydration and Anti-Aging: The Core of Skin Science

Your skin isn’t just a surface—it’s an organ with a full-time job. In this episode, we break down what really causes dryness and aging, and why your moisturiser might be doing less (or more) than you think. From humectants that pull in water to occlusives that lock it in and emollients that smooth everything out, we decode the science behind the products lining your bathroom shelf. We also dive into the powerhouse ingredients, like retinol, that can boost collagen and soften fine lines—and the irritation that sometimes comes with them. But above it all, dermatologists agree on one truth: the only real anti-aging secret is sunscreen. Tune in to learn what your skin actually needs.https://www.economist.com/science-and-technology/2025/03/01/is-posh-moisturiser-worth-the-money
