    Phloretin CF is a triple antioxidant cocktail formulation 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 by its structure has difficultly being effectively absorbed 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.

    Physical Fusion UV Defense SPF 50 is a breathable, tinted sunscreen formulated with transparent titanium oxide and zinc oxide (Z-Cote®), the only mineral UV filter shown to protect against the full UVA/UVB spectrum along with translucent color spheres and artemia salina to impart powerful UV protection with a natural radiance. A “shake then apply” dispersal technology helps ensure even distribution of sunscreen ingredients.
