There are three forms commonly used in cosmetics:

        • ascorbyl palmitate,
        • magnesium ascorbyl phosphate, and
        • L-ascorbic acid.

L-ascorbic acid is the most active form of vitamin C and has numerous benefits for the skin.  L-ascorbic acid is water soluble and must be formulated at low pH to stay active.
