Ascorbyl Glucoside (AA2G Ascorbyl Glucoside-Stabilized Vitamin C)  is a stabilized Ascorbic Acid with superior formulation stability. AA2G has proven to be effective at percentages as low as 2% and resists discoloration and degradation, while retaining all the biologic activity of L-ascorbic acid!  Ascorbyl Glucoside has the same lightening, sun protective and anti-aging properties as L-ascorbic acid.  Topical application of AA2G has been shown to prevent pigmentation of skin by suppressing melanin synthesis in melanocytes. It also has the ability to reduce the amount of pre-existing melanin, resulting in a lighter pigmentation of the skin. AA2G acts in the same manner as LAA without the limitation of LAA (ie. LAA needs an extremely low PH to perform effectively, AA2G does not!) Topical application of AA2G has been shown to prevent pigmentation of skin by suppressing melanin synthesis in melanocytes. It also has the ability to reduce the amount of pre-existing melanin, resulting in a lighter pigmentation of the skin so therfore AA2G acts in the same manner as LAA without the limitation of LAA.
