This daytime antioxidant serum blends the power of pure vitamin C (l-ascorbic acid) with a combination of 10% glycolic and lactic hydroxy acids at a pH that maintains their efficacy on skin. It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that is, by its structure, difficult to effectively deliver on skin The Duke Antioxidant patent describes the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.
