More than just a serum, One Essential Skin Boosting Super Serum detoxifies, regenerates and boosts skin for a revitalized complexion. Daily, skin faces an onslaught of aggressors: UV rays, stress and pollution. The solution: the new One Essential, with a more powerful formula that targets both outdoor and, for the first time, indoor toxins. One Essential quadruples the effects of active ingredients (such as retinol, vitamin C, longoza, bifidus and hyaluronic acid) in the skincare products that follow* for lasting radiance. This super serum is the fundamental first step, before any other skincare product, for a revitalizing effect.
