Ascorbic acid (vitamin C) is a water-soluble vitamin that is related to glucose. It can be found in citrus fruits and other vegetables (44). In its natural form, Vitamin C acts as a reducing agent in several metabolic processes.

Some studies have shown that Ascorbic acid (45) may help prevent ultraviolet-induced skin damage. Aging and excessive exposure to ultraviolet rays lowers the level of vitamin C in the body (46). Therefore, supplementation might be necessary.
