Much research suggests a causative link between oil oxidation and the formation of blemished skin. Upon skin’s oil oxidizing, this free radical damage can cause a cycle of inflammation and bacteria that can lead to blemish formation. Daily external aggressors like sun and pollution can generate free radicals that further oxidize skin oils.
Silymarin CF is clinically demonstrated to reduce oil oxidation by up to 76%.
This combination vitamin c serum and antioxidant serum is designed under the Duke Antioxidant patent. Vitamin C is a highly potent antioxidant that has difficulty 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 stands as the only brand to formulate antioxidants according to these parameters.
