Episode 2: Free Radicals & Antioxidants

In this podcast episode, Dr. Macrene Alexiades discusses the damage that occurs to the skin due to free radicals and the importance of antioxidants in protecting and repairing the skin. Free radicals are highly reactive molecules that can cause damage to proteins, lipids, and DNA in the skin. This damage can lead to skin aging and potentially skin cancer. Antioxidants work by neutralizing free radicals and preventing them from causing further damage. Dr. Alexiades emphasizes the importance of a varied diet and the use of topical antioxidants to protect the skin. She also mentions the need for DNA repair enzymes as an additional layer of defense against mutations.
