Rating: GOOD

What is it doing: Type of clay that’s a mix of bentonite (another clay) and fuller’s earth, the latter being a white to brown substance found in sediment. Like all clays, montmorillonite has absorbent properties and can be a helpful ingredient for oily skin. It also functions as a thickener.

Found in:  MOISTURE-BURST MASK (TROPICAL, POLAR, DESERT CLIMATES)
