Science
SkinCeuticals research shows that specific combinations of antioxidants, when effectively formulated, perform synergistically to provide results superior to each single antioxidant formulation. 

Published in 8 peer-reviewed scientific journals, C E Ferulic is a vitamin C serum formulated under the Duke Antioxidant patent. The Duke Antioxidant patent describes 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. 

Shield Against Atmo3spheric Aging
Ground level ozone (O3) pollution is shown to cause signs of premature aging.
New ground-breaking SkinCeuticals science shows over-exposure to ozone pollution may cause visible skin aging, and topical antioxidant use can help prevent the impact of ozone damage to skin. For the first time ever, SkinCeuticals C E FERULIC was shown to help shield against signs of skin-aging induced by ozone (O3) pollution.
