Obagi Professional-C Serum 10% formulation uses stabilized ascorbic acid, the only form of Vitamin C that can be effectively absorbed by the skin. With a concentration of 10% ascorbic acid, this specific formulation is tailored to those individuals who have dry, sensitive, or reactive skin. 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.
