L-Ascorbic Acid 2-phosphate (magnesium salt)

Ascorbyl phosphate is a synthetic form of Vitamin C and is found in different salt forms such as magnesium ascorbyl phosphate and sodium ascorbyl phosphate. These salts are present in cosmetic products at concentrations ranging from 0.001 % to 3% [A27211]. As vitamin C is susceptible to breakdown of compound and discoloration in cosmetic formulations, ascorbyl phosphate, along with other Vitamin C derivatives, acts as an active and stable precursor of vitamin C that is readily absorbed into the skin with a hydrating effect on the skin [A27212]. While ascorbyl phosphate salts provide a constant delivery of vitamin C into the skin, they also mediate an antioxidant action to act as a free radical scavenger and increases collagen production *in vitro* [A27212].
