The Vitamin C Serum is a light, penetrating serum that has excellent absorbency into the skin. This lightning, brightening serum will become your new go-to favorite. Vitamin C comes in many different forms both naturally sourced to synthetic varieties. Russell Organics uses Ascorbic Acid Peptide, derived from citrus fruit. The reason this is important is that Ascorbic Acid Peptide has been proven to be a very stable source of Vitamin C. A common issue with lesser quality Vitamin C ingredients is that they are simply too unstable and lose their efficacy very quickly in the packaging before they even reach your skin. Ascorbic Acid Peptide is a powerful antioxidant that imparts magnificent benefits for the skin, but like most antioxidants must be packaged properly to retain its effectiveness.
