All Skin Types, Including Sensitive.

Obagi Professional-C Serum 20% is the strongest formula in Obagi's Professional-C line, delivering a concentrated 20% L-ascorbic acid vitamin C serum in a 1 fl oz bottle. L-ascorbic acid is one of the most researched and effective forms of vitamin C for skin, used here to target dullness, uneven tone, and visible signs of aging.
Key Ingredients
  • 20% L-ascorbic acid, the highest concentration in the Professional-C range
  • Ascorbyl glucoside, a stabilized vitamin C derivative
  • Sodium hyaluronate for added moisture retention
  • Formulated for enhanced penetration and absorption
Key Benefits
  • Helps brighten skin and reduce the appearance of hyperpigmentation and dark spots
  • Supports antioxidant defense against environmental stressors
  • Helps minimize the look of fine lines and improve overall skin texture
How To Use

Formulated specifically for normal to oily skin. Because it's the highest-strength option in the Professional-C line, it's best suited for those already accustomed to vitamin C serums who want a potent daily antioxidant treatment rather than first-time users with sensitive skin.
