ONE BY KOSÉ Pore Clear Oil Mini Size 14ml Easy and thorough pore care with your daily cleansing routine. Removes stubborn keratin plugs, leaving skin moist and smooth after washing. No matter how much you care for your skin, clogged pores and blackheads keep coming back. One of the reasons is the "hardened keratin plugs" produced by the harsh pore environment. Contains ultra-fine cleansing ingredients, about 1/20,000th the size of a pore, to loosen and dissolve hardened keratin plugs. It removes them gently, and quickly washes them off with your makeup.
