Bentonite

Bentonite is a natural absorbent clay formed from volcanic ash. It is highly valued in skincare for its strong ability to absorb excess oil, impurities, and toxins from the skin. When mixed with water, it forms a paste, making it a popular ingredient in detoxifying masks.

Whether it can reduce excess sebum, shine, or greasiness — absorbents, sebum-regulating ingredients, and some acne actives.
