As we all know, it is important to protect the skin from harmful sun rays, and ultraviolet rays are one of the most common free radicals that we are exposed to. Prolonged exposure to ultraviolet light is the most common cause of skin cancer. Vitamin E is an important nutrient and antioxidant that we need to maintain our health. It can resist free radicals, such as pollution, radiation and ultraviolet rays from the sun. These free radicals can cause cells to age prematurely, leading to diseases like cancer. Ensuring adequate vitamin E intake is vital to your immune system and health.
