Obagi Professional-C Serum provides antioxidant protection with deep penetration to the dermal layer. The 10% L-Ascorbic acid helps contribute to collagen synthesis. Obagi Professional-C Serum 10% is suitable for dry, sensitive or reactive skin.
Formerly: Professional C High Potency 10% Vitamin C Serum
Apply 5-7 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.
Store in a dark Cool Place. Keep cap on tightly when not in use.
I have used Professional-C Serum 10% for over 5 years. Provides a smooth, nourishing base under the sunscreen cream also by Obagi.
Pros: Makes your skin feel great.
Cons: Do not use on broken skin or right after brow waxing.
