Obagi Professional-C Serum 20% is an effective skin protectant and conditioner that prevents damaging UV rays and free radicals from taking their toll on skin. Professional-C also visibly reduces wrinkles, fine lines and other signs of aging. The Professional-C Serum is available in four different formulas, with concentrations ranging from 5% (for eyes), to 10%, 15% and 20%.

Thanks to Obagi's patented Penetrating Therapeutics™ technology, Professional-C Serum also penetrates deeper into skin than most other Vitamin C products.
