A healthy diet overall is important for building a strong blood supply that carries oxygen and nutrients to the skin and removes waste products. Antioxidants, especially vitamins C and E, selenium, beta carotene, lycopene, etc, protect skin from oxidative damage from UV light, and healthy fats such as the omega-3s also are important for healthy skin. In contrast, saturated and trans fats have been linked to increased skin aging. An entire chapter in my new book, Eat Your Way to Sexy, talks about the dietary tips to look up to 15 years younger, including also rubbing some nutrients onto the skin, such as vitamin C. But, there’s a catch. Vitamin C is only effective if supplied in a 10% solution or higher. Lower levels will do next to nothing. So nourish your skin from inside and from the outside, too!
