Vitamin C (ascorbic acid) is an antioxidant known as the “beauty vitamin” for skin. It has the appearance of white crystals that dissolve well in water. It has a sour taste and no odor. When interacting with oxygen, it oxidizes, acquiring a dark orange hue.
The antioxidant properties of vitamin C, or ascorbic acid, are now widely known and studied. However, more and more new data are emerging on the importance of this compound in collagen synthesis, participation in melanogenesis, restoration of photodamaged cells and other, no less useful, properties. Entering the human body with food or topically, vitamin C is involved in maintaining skin health, having a beneficial effect on its cells.
Ascorbic acid in its structure is a derivative of carbohydrates. There are four optical isomers of ascorbic acid, two of which are biologically active and have the L configuration. In the human and animal body, the reduced form of ascorbic acid (AA) and the oxidized form - dehydroascorbic acid (DAH) - can quickly and reversibly transform into each other, participating in redox reactions
