Bentonite clay is a natural clay formed from volcanic ash, primarily composed of montmorillonite. It is known for its ability to absorb water and expand, making it useful in various applications, including construction, drilling, and cosmetics. Its unique properties allow it to bind with toxins and impurities, which is why it is often used in detoxifying products. In addition to its industrial uses, bentonite clay is popular in skincare for its cleansing and exfoliating properties. It can help remove excess oil and impurities from the skin, making it a common ingredient in face masks and other beauty treatments.
