SkinCeuticals research shows that specific combinations of antioxidants, when effectively formulated, provide superior results to each single antioxidant formulation.
Phloretin CF is a triple antioxidant cocktail formulation shown to provide broad-range 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 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.
SHIELD AGAINST ATMOSPHERIC AGING
SkinCeuticals defines atmospheric aging as the visible result of a range of environmental aggressors on skin, including UV, infrared radiation (IRA), and pollution. Ongoing SkinCeuticals research shows that over-exposure to these aggressors may cause visible skin aging, and topical antioxidants can help prevent the impact to skin.
