OC8 Professional Mattifying Gel works continuously for up to 8 hours absorbing excess oil. The results? Even-toned, true matte skin for that just-applied look throughout the day. OC8 contains ACRYSORB® micro-particles that are specially designed with copolymer technology and work to permanently trap up to 6X their own volume in oil. OC8 traps facial oil mechanically on the skin’s surface. The oil remains locked away, invisible to the naked eye, without compromising your skins natural moisture. 1.6 oz.
