Function
Obagi-C serum contains L-ascorbic acid, or vitamin C, which is a powerful antitoxidant. Antitoxidants neutralize the effects of environmental free radicals, or harmful molecules, on the skin. Free radicals can damage your skin and accelerate the aging process. According to the Obagi-C manufacturer's website, by applying a vitamin C-based serum like Obagi-C to your face, neck and chest at least once a day, you can protect your skin from the damage caused by these free radicals. Obagi-C serum can help prevent wrinkles and other signs of premature aging.
Types
Obagi-C Serum comes in four different concentrations. The 20 percent version is for people who want the highest amount of L-ascorbic acid in the serum. The 15 percent concentration is for all skin types. The 10 percent version is for dry or sensitive skin, and the 5 percent concentration is designed to be used in the eye area.

According to the manufacturer's website, Obagi-C serum helps your skin maintain its brightness by ensuring that your skin maintains normal cellular renewal. The serum also helps reduce inflammation, builds collagen within your skin and can help prevent future wrinkles. In addition to these properties, the website states that Obagi-C serum helps maintain a comfortable moisture balance within your skin. Even if you have sensitive skin, you can obtain the benefits provided by Obagi-C serum, as it is nonirritating.
