VITAMIN A HELPS WITH SUN EXPOSURE Vitamin A repairs skin damage caused by the sun, according to a study published in Clinical Cancer Research (2004;10:1875.80). Sun exposure has both positive and negative aspects: Too much sun, however, damages the skin, and increases the skin cancer risks. The cumulative effect of years of exposure to the sun's ultraviolet rays can cause patches of severe skin damage that can progress to nonmelanoma forms of skin cancer (known as basal cell or squamous cell cancer). There are about one million new cases of nonmelanoma skin cancer in the United States each year. Vitamin A, an antioxidant nutrient has been shown in many studies to prevent and reverse cancerous changes in cells in some parts of the body, including the skin. These findings are especially important given the rising incidence of skin cancer in many parts of the world.
