Vitamin C or L-ascorbic acid or L-ascorbate is an essential nutrient for humans and certain other animal species. In living organisms ascorbate acts as an antioxidant by protecting the body against oxidative stress.[1] It is also a cofactor in at least eight enzymatic reactions including several collagen synthesis reactions that, when dysfunctional, cause the most severe symptoms of scurvy.[2] In animals these reactions are especially important in wound-healing and in preventing bleeding from capillaries.http://www.elitedepot.com/Obagi-CLENZIderm-MD-Starter-Set-Normal-to-Oily-Please-Note-Serum-Gel-is-discontinued-Therepeutic-Lotion-will-be-shipped-in-its-place_p_25.html
