Kaolin clay is the most gentle and mild of all clays used in skin care.It smooths, exfoliates, and detoxifies the skin, absorbs excess oils, and fights acne; it can strengthen and improve skin health and brighten your complexion. It also has been shown to have antibacterial and antiseptic properties. This clay is very gentle and mild and has a relatively low pH level—between 4 and 5—which is close to the skin’s natural pH of 5.5. These characteristics make this clay ideal to retain the integrity of the skin and to protect the skin barrier. Clays are effectively used in facial masks as their high absorbency can draw out oils, toxins, pollutants, and bacteria but they offer a number of skin-enhancing benefits.
