Ascorbic Acid
Benefits & Use Cases
Part of the Vitamin C family of ingredients, L-ascorbic acid is Vitamin C in its purest form, and the active form required by the body to result in the many skin skin benefits of Vitamin C. The issue with L-ascorbic acid is in the delivery, as it is very unstable in water, and needs a pH 4 or below for it to penetrate the skin. That being said, when it can be stabilised in a formula and is able to penetrate the skin, it provides the highest potency of any form of Vitamin C currently available.
Vitamin C can also be found on ingredients lists as ascorbyl glucoside, ascorbyl palmitate, ethyl ascorbic acid, l-ascorbic acid, magnesium ascorbyl phosphate, sodium ascorbyl phosphate and tetrahexyldecyl ascorbate.
