Phloretin CF Gel

SkinCeuticals research shows that specific combinations of antioxidants, when effectively formulated, provide superior results to each single antioxidant alone. Phloretin CF Gel is a topical vitamin C antioxidant suspended in a gel delivery system. In a comforting texture, this vitamin C gel has been shown to provide powerful environmental protection due to a synergistic combination of 2% phloretin, 10% pure vitamin C (l-ascorbic acid), and 0.5% ferulic acid. 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 a topical 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.
