Vitamin C is the most abundant natural antioxidant in human skin. Although most plants and animals have the ability to synthesize it, the human body is unable to produce it. Because of this, it should be obtained through dietary sources such as citrus fruits and leafy vegetables. In addition, Vitamin C for the skin can also be obtained through the use of cosmetics. Its action is capable of acting both in the control of enzymes responsible for degrading the tissue and leading to skin aging, as well as inhibiting the excess production of melanin, contributing to a decrease in the darkened appearance of the skin surface. Classified as a substance indispensable for the prevention and fight against aging and hyperpigmentation.
