What is Bentonite?

A natural clay that powerfully absorbs sebum and impurities

Primarily used in mud masks for oily and blemish-prone skin. Has a strong sebum-absorbing effect on pores.

Key properties & actions

Bentonite is a natural clay formed by the long-term weathering of volcanic ash. Its particle surfaces carry a negative charge, which is known to attract and adsorb positively charged sebum, waste products, and impurities. It has the characteristic of swelling and becoming viscous when it comes into contact with water, making it well suited to mask formulations.

How to manage

It is typically used 1–2 times per week in the form of a wash-off mud mask. It is advisable to rinse it off with lukewarm water while the mask is still slightly moist rather than allowing it to dry completely. Because its strong adsorbing action may cause a feeling of dryness, it is recommended to follow up with thorough moisturization. If irritation recurs, reducing the frequency of use is advised, and consulting a dermatologist is recommended if irritation is severe or persistent.

Good to know alongside

It is often mentioned alongside other clay ingredients such as kaolin and Moroccan rhassoul clay, and frequently appears in discussions of sebum adsorption and pore care.

Everyday care tips

Applying the mask only to oil-prone areas such as the T-zone — rather than all over the face — may help reduce dryness.
