SILICA

Silicon dioxide is used in cosmetics as an anti-foaming agent, anti-caking agent, filler, binder, skin-conditioning agent, lubricant, suspending agent, and viscosity-increasing agent. Skin care products containing silica may be well-suited for oily skin, as they help absorb excess sebum and leave the skin feeling matte, refreshed, and powdery.(1)
