Skinceuticals C E Ferulic

SkinCeuticals research shows that specific combinations of antioxidants as is in C E Ferulic, when effectively formulated, perform synergistically to provide results superior to every single antioxidant formulation.
Published in 8 peer-reviewed scientific journals, Skinceuticals Serum C E Ferulic is a vitamin C serum formulated under the Duke Antioxidant patent. The Duke Antioxidant patent describes the effective delivery of vitamin C to the 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.
