In this episode of the ZOE Science & Nutrition podcast, Jonathan interviews Professor John McGrath, a leading dermatologist, to debunk common myths about anti-aging skincare. They discuss the science behind skin aging, including the role of collagen, the skin microbiome, and the impact of lifestyle factors like sun exposure and smoking. Professor McGrath clarifies that expensive creams often don't penetrate deeply enough to erase wrinkles and that collagen supplements are unlikely to directly increase skin collagen. He emphasizes the importance of a simple skincare routine consisting of cleansing, moisturizing, and sunscreen, while also highlighting the benefits of moderate sun exposure for overall health. Additionally, he shares a surprising tip about using high-dose vitamin D3 to reverse sunburn and offers advice on the use of retinol and the potential benefits of incorporating the GAC fruit into one's diet for skin health.
