Science
A triple antioxidant cocktail formulation offers broad-range environmental protection due to a synergistic combination featuring 2% Phloretin, 10% pure vitamin C (L-ascorbic Acid), and 0.5% Ferulic Acid. This protective face serum also improves the appearance of discoloration.
Phloretin CF is formulated under the Duke Antioxidant patent which ensures effective delivery of vitamin C to skin. In order for a vitamin C serum to be effective it must be formulated with pure L-ascorbic Acid (vitamin C) at an acidic pH within the 2.0-3.5 pH range and have a concentration between 10-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.
