Whitening "Grandfather" VC
01
What is VC?
VC (Vitamin C) Also known as L-ascorbic acid, it exists in plant cell walls. It is a water-soluble vitamin and is easily oxidized. It plays a regulatory role in human redox metabolism. It can promote collagen and connective synthesis, promote wound healing, and protect cells from oxidation.
VC plays an important role in human body, and it is a basic antioxidant and anti-aging ingredient in food, YAO and skin care products.
When cosmetics are used, on the basis of prototype VC, some VC derivatives are derived. Compared with prototype VC, the properties of derivatives are more stable, less irritating, and are not easily oxidized, but they cannot be directly utilized. According to the absorption, penetration and conversion rate, the efficacy is slightly different from that of prototype VC.
