Professional-C® Serum 20%
Obagi Professional-C® Serum 20% is our highest concentrated serum, packed with antioxidants to help minimize the appearance of fine lines and wrinkles while leaving skin feeling silky soft. This high-performance serum is formulated with 20% L-ascorbic acid (Vitamin C), and is best suited for normal to oily skin. As we age, our skin doesn’t snap back like the way it did in our younger years, resulting in more signs of skin aging, such as the appearance of fine lines and wrinkles.
Apply 5 to 7 drops of Obagi Professional-C® Serum to the face, neck and chest using fingertips to cleansed skin in the morning before sunscreen or makeup application.
