Kaolin Clay is named after the Kao-ling mountain in China, where the clay was mined for centuries. It has been used for facial masks, poultices, soaps, scrubs, deodorants and facial powders. Kaolin clay is a fine and light clay that has natural absorbency properties. When applied on skin, mixed with a little warm water, it will soak up excess oils and stale sebum on the skin and within the pores. Since it has detoxifying effects, kaolin clay sucks out impurities such as grime, dirt, pollution and germs from the pores. This cleanses out the pores and prevents them from clogging up and causing breakouts.
