• Clinical data illustrates that the combination of the potent vitamin C and 4% hydroquinone results in 10 times better penetration than the leading competitor*
• Glycolic acid lightly exfoliates the stratum corneum to condition and prepare the skin for better penetration of active ingredients through all layers of the skin

A decrease in bioavailable L-ascorbic acid equates to an increase in the oxidized, non-bioavailable form of L-ascorbic acid, L-dehydroascorbic acid

*L-ascorbic acid was determined at baseline and 4 weeks via L-ascorbic acid titration.
