Vitamins are not only important to keep the body healthy, but also to make our skin feel and look good. Vitamin A, for example, has an antioxidant action, counteracting the formation of free radicals and decelerating skin aging. Vitamin C plays a fundamental role in the production of collagen, the elastic fiber responsible for skin tone and firmness, brightens the complexion and helps reduce sun spots. Vitamin E acts as a protective shield and is able to block oxidative stress, which causes damage to skin cells.
