Ever wonder why your skin changes so much in winter? In this episode of Biohacking Beauty, we explain what actually happens when humidity drops, TEWL rises and indoor heating pulls moisture from the skin. We also talk about UVA exposure in cold months, lifestyle shifts that increase oxidative stress and why winter puts more pressure on your skin’s repair systems. We break down the winter ingredients that matter most, like ceramides, barrier lipids, vitamin F, beta glucan, hyaluronic acid, peptides, NAD precursors and exosomes, and how to use them in a routine that supports barrier strength and cellular energy. We also share simple protocol adjustments for different climates and biological skin ages. If you want a clear strategy for keeping your skin healthy and supported through the colder months, this episode gives you everything you need.
