Kaolin, also known as white clay or china clay, is a soft clay that’s been used in China for centuries to create porcelain products. It’s also used widely in skin care products, toothpastes, and hair products.
Clay face masks that contain kaolin are thought to have several benefits, such as preventing acne, managing dry skin, and absorbing excess oil or sebum. Kaolin is also thought to be the mildest and most gentle clay used in skin care.
Although most of the evidence that backs clay masks is anecdotal, some studies suggest that these masks may have skin benefits.
