Christian Dior One Essential Skin Boosting Super Serum 1.7oz / 50ml A powerful serum that detoxifies, regenerates, and boosts skin for a revitalized complexion. Daily, skin faces an onslaught of aggressors including UV rays, stress, and pollution. The solution: the new One Essential, with a more powerful formula that targets 100 percent of both outdoor (microparticles, heavy metals) and—for the first time—indoor toxins (per an in vitro test on ingredients) such as carpet, glue, varnishes, and electronic devices. This Super Serum is the fundamental first step, before any other skincare product, for a revitalizing effect. When applied twice per day, One Essential purifies and strengthens the skin, and the effectiveness of your usual skincare routine is boosted and prolonged by up to four times.
