Obagi Professional-C Serum 10% is formulated with 10% L-ascorbic acid, the only form of vitamin C suitable for topical application. L-ascorbic acid reaches the deepest layers to the skin to provide superior antioxidant protection, defend against damaging UVA and UVB sun rays, contribute to collagen synthesis and help prevent premature signs of aging such as fine lines and wrinkles.
Suitable for dry, sensitive or reactive skin types, Obagi Professional-C Serum 10% also reduces inflammation to help soothe irritated skin. Professional recommendation is advised.
Apply 5 to 7 drops of Obagi Professional-C Serum to the face, neck and chest using fingertips. Apply to cleansed skin in the morning before sunscreen and makeup application. A slight tingling may occur in some people, which diminishes with continued use.
