Grooming Clay: It’s Not Just for Face Masks
What Is This Stuff, Exactly?
The five most common clays in the beauty aisle
The main ingredient in porcelain, white kaolin is the gentlest and most-used clay in cosmetics. It won’t sap much moisture and still softens and exfoliates.
This magnesium-rich volcanic ash is absorbent and has a positive electrical charge, making it a magnet for dirt and oil. It’s especially useful for those with acne.
Mined from mineral deposits in Morocco’s Atlas Mountains, where it’s been prized since the eighth century, rhassoul is most often sought for its skin-firming capability.
Once used by textile workers (or “fullers”) to clean shorn wool, this is a mixture of clays, including bentonite and kaolin, but especially montmorillonite, which is unique for its mild bleaching property.
Found mostly near ancient marine beds, it gets its color from iron oxide and decomposed plants. It tightens pores, helps circulation, exfoliates, and is sometimes used to treat arthritis and sore muscles.
