Obagi Professional-C 20% offers maximum daily antioxidant protection and greater penetration than other Vitamin C products. The greater the penetration, the greater the antioxidant benefit to your skin. Double your protection with this 2-bottle value pack.

Obagi Professional-C 20% vitamin C serum infuses your skin with L-ascorbic acid, the only form of vitamin C suitable for topical application. Designed to penetrate deep into your skin, it provides antioxidant protection from UV damage as it brightens away hyperpigmentation and encourages the growth of new collagen and elastin fibers. Additionally, hyaluronic acid binds moisture to your skin to prevent dryness, for a soft and supple texture.
