Bentonite Clay

Bentonite

A strongly absorbent clay for oily, congested skin — too drying for dry or sensitive skin. Once a week is plenty.

What it does

It’s a strongly absorbent clay that soaks up a lot of oil. It’s used in masks for oily and acne-prone skin, where it helps clear clogged pores. On dry, sensitive or damaged skin it can dry the barrier out further. Once a week is usually enough.

The EU’s ingredient database lists it as a thickener (controls how thick the product is), a stabilizer (helps oil and water stay mixed) and an absorbent (soaks up water or oil).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗

The evidence, graded

expert consensusIf skin is reactive, peeling, stinging, or burning unexpectedly, pause all actives — retinoids, benzoyl peroxide, AHAs, BHAs and vitamin C — and rebuild the barrier with a simple cleanser, a moisturizer and SPF for 2–4 weeks before re-introducing actives one at a time.Lodén 2003 · American Journal of Clinical Dermatology ↗
