Overview

Kaolin is a type of mineral clay (a native hydrated aluminum silicate). The mineral is milled into a white, very fine powder that has many different applications in skincare.

It often forms the base of cosmetics such as eyeshadows, powders, foundations, and face masks. It is able to absorb sweat and oil - which helps to keep the skin matte.

Kaolin is used to give liquid preparations an opaque white look, and the larger particles have found their way into skin scrubs as an abrasive ingredient.
