Bentonite Clay (Bentonite) is primarily used for deep cleansing, pore minimising, oil absorption. The mechanism: Negatively charged clay draws out positively charged toxins and sebum via adsorption.
The scientific name is Bentonite. Negatively charged clay draws out positively charged toxins and sebum via adsorption. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 5–25% (masks). Best suited to oily, combination, acne-prone skin. Primary applications: deep cleansing, pore minimising, oil absorption.
Works well with: Kaolin clay, salicylic acid. Avoid combining with: Overuse can strip barrier — limit to 1–2x/week.
Volcanic ash-derived; swells with water to form gel.
