Combining ferulic acid with vitamins C and E provides eight times the skin’s natural protection against UV radiation as compared to four times the protection provided by vitamin C and E, and twice the skin’s natural protection provided with vitamin C or E alone.
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
In the morning after cleansing and toning, apply 4–5 drops to a dry face, neck, and chest before other anti-aging skincare products. Complete your regimen with a SkinCeuticals sunscreen. When used together, SkinCeuticals antioxidants and broad spectrum sunscreens provide protection against visible aging caused by environmental aggressors.
