L - Ascorbic Acid - Vitamin C is an organic acid with antioxidant properties. The L-enantiomer of ascorbic acid is commonly known as vitamin C.

Vitamin C is used in skin care products in the form of ascorbic acid at a typical 10% concentration and low ph. It was thought that a minimum 10% concentration was required but newer information indicate that lower concentration (5%) may have benefit.

Cosmetic Uses:Vitamin C, 100% L-Ascorbic Acid, is best utilized in a water/lipid solution (lotion, cream or emulsion) instead of strictly water based formulation.
