There are many natural ingredients that can be used to make a face mask. Kaolin clay is one of the quickest and most effective to use. It’s a natural absorbent and by adding water it binds with oils and other impurities to remove them from the skin. This is why it’s often combined with bentonite clay. Kaolin clay also contains silica which is important for strengthening the skin and can damage the protective barrier in your skin leaving it vulnerable to bacteria and pollution. The benefits of Kaolin clay in a face mask include removing oil, dead skin cells, dirt and improving skin elasticity and tone.
