Obagi Professional-C Serum 20% formulation uses stabilized ascorbic acid, the only form of Vitamin C that can be effectively absorbed by the skin. With a concentration of 20% ascorbic acid, this specific formulation offers the deepest level of penetration available. L-ascorbic acid neutralizes free radicals that would otherwise damage your skin, helps stimulate collagen synthesis, provides sun protection, and remains in the skin for up to 72 hours. Professional-C Serums are absorbed into your skin quickly, so you benefit almost instantly after application. Obagi Professional-C Serums offer maximum antioxidant protection you won’t find in other Vitamin C products.
Professional-C Serums provide maximized results when used as a supplement to the comprehensive Obagi Nu-Derm System.
