Our skin cells may regenerate quickly, but they deal with attacks from all sides, from both inside and outside the body. Our skin is susceptible to weather conditions, physical damage, temperature changes, moisture fluctuation, radiation, free radicals, and more. This means that protecting our skin requires a wide arsenal of healthy tools and nutrients to keep it safe. Antioxidants serve as protection against the cell damage that free radicals can cause by terminating the free radicals reaction with those cells. Some antioxidants are products of normal metabolism and others are found in food.
