Obagi Professional C 20% Serum uses stabilized ascorbic acid, the only form of Vitamin C that can be effectively absorbed by the skin. It provides superior antioxidant protection with deep penetration to the dermal layer. The 20% L ascorbic acid helps in defending against damaging UVA and UVB rays, helps prevent premature sign of aging such as fine lines and wrinkles, and contributes to collagen synthesis. Obagi Professional C Serum 20% is recommended for normal to oily skin.
Directions For Use
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.
