Obagi Professional-C Serum 20% uses stabilized ascorbic acid – the only form of vitamin C that can be effectively absorbed into the skin. Vitamin C neutralizes free radicals to help prevent skin cell damage. Obagi Professional-C Serum provides superior antioxidant protection with deep penetration to the dermal layer. The 20% L-ascorbic acid helps in defending against UVA and UVB light rays, which contribute to premature aging, wrinkles, and lines. Application of the serum will contribute to collagen synthesis and bring back the skin’s youthful resilience. This product is recommended for normal to oily skin.
