Kaolin is a fine aluminium silicate clay with a layered structure and a mild surface charge, so it takes up oil and loose debris that are already on the surface. It is less absorbent than bentonite, which is why it dries skin less and suits a wider range of skin types. As the mask dries, evaporation from the clay pulls water from skin too — which is why leaving it on until it cracks is counterproductive.
