Anti-Oxidant Vitamin Serum



One of the first and only serums to harness the skin-repairing and preserving power of five, antioxidant-packed vitamins: A, C, E, F and K. All five vitamins work synergistically to help brighten undertone, smooth texture and increase firmness, as well as preserve skin by strengthening its protective barrier—the key to preventing future damage. Skin-nourishing ceramides, jojoba and African Savannah Tree marula oil bind moisture to the skin for radiant hydration you can see and feel. You will love how this serum elegantly slips over skin and creates the most beautiful, velvety-matte makeup base. 

In one week, skin texture looks and feels smoother and tone appears visibly brighter. After four weeks of consistent use, skin firmness is noticeably improved.

      I see a difference

      The Koo Anti-oxidant vitamin serum has helped to bring my skin a new level of healthy looking brightness. It’s helped to dramatically improve the redness and soften the texture of my skin.
