SkinCeuticals C E Ferulic® with 15% L-Ascorbic Acid
is a high-performance antioxidant serum that’s widely regarded as one of the best vitamin C serums for skincare, especially for combating signs of aging and protecting skin from environmental damage. It’s formulated with a potent combination of antioxidants — vitamin C (L-ascorbic acid), vitamin E (alpha tocopherol), and ferulic acid — to deliver powerful anti-aging and protective benefits. 

This is a daytime antioxidant serum designed to be applied after cleansing and toning (before moisturizers and sunscreen). It helps protect skin against environmental aggressors — such as pollution, UV exposure, and free radicals — that can accelerate aging and damage the skin.
