SCIENCE
Mentioned extensively in peer-reviewed scientific journals, C E Ferulic is a vitamin C serum demonstrated to provide powerful environmental protection due to a synergistic combination of 15% pure vitamin C (l-ascorbic acid), pure vitamin E (alpha-tocopherol) 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 by skin.
The Duke Antioxidant patent outlines 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
Use

When used together, SkinCeuticals antioxidants and broad spectrum sunscreens provide protection against visible aging caused by environmental aggressors.
