Ascorbic acid (vitamin C) is a water-soluble vitamin that is related to glucose. It can be found in citrus fruits and other vegetables. In its natural form, Vitamin C acts as a reducing agent in several metabolic processes.
Some studies have shown that Ascorbic acid may help prevent ultraviolet-induced skin damage. Aging and excessive exposure to ultraviolet rays lowers the level of vitamin C in the body. Therefore, supplementation might be necessary.
