Obagi's Professional-C Microdermabrasion Polish Mask exfoliates and brightens with ultra-fine crystals that gently buff away the dull, outer layers of skin and infuse the freshly revealed skin with potent and brightening 30% L-Ascorbic Acid. This multitasking product gently exfoliates at the surface to ensure that key ingredient Vitamin C can easily and deeply penetrate the skin, leading to better absorption and optimum results. Conditioning botanical oils minimise dry patches and with regular use, the skin's texture becomes more refined, and visible signs of ageing are reduced.
