BENTONITE
Description
Bentonite is a naturally occurring clay mineral derived from volcanic ash, prized for its exceptional absorption and detoxifying properties in skincare formulations. This fine, odorless powder is composed primarily of montmorillonite, a type of smectite clay with a unique layered structure. When hydrated, bentonite swells significantly, forming a colloidal gel with a high surface area and strong negative charge.
In skincare, bentonite acts as a powerful adsorbent, attracting and binding toxins, impurities, and excess sebum from the skin's surface and pores. Its drawing action makes it particularly effective for oily and acne-prone skin types. Bentonite also exhibits mild exfoliating properties, helping to remove dead skin cells and promote cell turnover.
The clay's mineral content, including silica, aluminum, and magnesium, may provide additional benefits such as improving skin elasticity and reducing inflammation. Bentonite is commonly used in face masks, cleansers, and spot treatments. It can be mixed with water or other liquids to form a paste, or incorporated into various skincare formulations. While generally safe for most skin types, bentonite may be drying for some individuals, necessitating proper hydration post-application.
