In the morning after cleansing and toning, apply 4-5 drops to a dry face, neck, and chest before all other skincare products.

Complete your skincare regimen with a SkinCeuticals sunscreen.

When used together, SkinCeuticals antioxidants, including Vitamin C serums and broad spectrum sunscreens provide more comprehensive protection against visible ageing caused by environmental aggressors.

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. Vitamin C is a potent antioxidant that is, by its structure, difficult to effectively deliver 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%.

15% L-ascorbic acid: Lauded for its superior antioxidant benefits, L-ascorbic acid is a highly potent form of pure vitamin C that helps neutralise free radicals and protect against oxidative stress, while providing visible anti-ageing benefits.

1% alpha tocopherol: This pure form of vitamin E neutralises free radicals and replenishes skin lipids.  It has been proven to act synergistically with vitamin C.

0.5% ferulic acid: A plant-based antioxidant, ferulic acid neutralises free radicals and enhances the antioxidant benefits and stability of vitamins C and E.
