Obagi Professional-C Serums

Targeted Vitamin C serums in 4 concentrations that can help reduce the signs of skin damage caused by the sun and other environmental stressors.

The Obagi skin care line introduces a vitamin C serum for maximum protection from aging free radicals.


This formulation of Obagi Professional-C Serum contains the highest concentration of L-ascorbic acid available. Although antioxidants for the skin come from many sources, from vegetables and vitamins to skin care products, L-ascorbic acid, the active ingredient in this Obagi serum, is the only form of vitamin C proven to penetrate the skin. For a potent dose of antioxidants for the skin, order this effective anti-aging formula.


What are free radicals and how does this Obagi serum minimize their aging effects?


Produced both inside and outside of the body, free radicals are the primary causes of fine lines, wrinkles and other signs of skin aging. Externally, free radicals result from environmental factors such as UV rays, air pollution, cigarette smoke and pesticides. These highly unstable molecules damage DNA and collagen, eventually leading to cellular damage and decreased skin elasticity. Although the body has natural processes to protect itself against free radicals, this ability declines with age. Antioxidants for the skin in this Obagi serum make skin appear more youthful and minimize the effect of free radicals by breaking them down into compounds the body can handle.

Obagi Professional-C Serum 20% offers superior skin penetration for visible results.


Even the most effective ingredients and antioxidants for the skin won’t achieve results unless they can penetrate the skin. The unique formulation of this vitamin C serum allows for greater product penetration. In clinical studies, Obagi Professional-C Serum has been shown to penetrate into the skin up to two times more than competing antioxidant products. Even 24 hours after application, this vitamin C serum shows signs of excellent absorption into multiple layers of the skin. To fight free radicals for lasting anti-aging effects, purchase this Obagi serum!

To suit your skin type and skin concerns, Obagi skin care offers antioxidants for the skin in several strengths.


This vitamin C serum from Obagi skin care is also available in three other formulations:

  • 15%, for normal skin
  • 10%, for sensitive, dry, or reactive skin
