Bentonite Clay

INCI: Bentonite

What is it?

A natural clay mineral used in masks and cleansers for its oil-absorbing and mild clarifying properties.

What does it do?

According to PubMed, a 2023 clinical study of a clay face-mask formulation (containing both kaolin and bentonite) in 75 adults with oily/combination skin found significant improvements in acne-related outcomes, sebum content and skin hydration after 4 weeks of twice-weekly use, with high product tolerability -- real clinical evidence, though from a multi-ingredient mask formulation rather than bentonite clay tested in isolation.
