Ascorbic acid (vitamin C), also known as L-ascorbic acid, levo vitamin C, and levo vitamin C, is a natural antioxidant used to prevent and treat skin sunburn.

The human body itself cannot produce vitamin C and must be ingested from the outside world. In cosmetics, vitamin C interferes with melanin production by interacting with copper ions at the active site of tyrosinase to reduce multi-step melanin synthesis processes such as dopamine quinone, which has a good whitening and freckle removing effect. It also has anti-inflammatory effects.

Currently, L-ascorbic acid remains the most biologically active and research-oriented.

L-ascorbic acid is a hydrophilic and unstable molecule, but due to the hydrophobic properties of the stratum corneum, its permeability in the skin is not very good; Due to the fact that L-ascorbic acid is a charged molecule, this instability further limits its transdermal penetration. An effective method is to add ferulic acid to achieve the transformation of L-ascorbic acid molecules from charged to uncharged molecular forms, while reducing the acidity of L-ascorbic acid to below 3.5, which means that L-ascorbic acid can remain stable and penetrate the stratum corneum.
