In the world of natural skincare, Bentonite Clay vs Multani Mitti are two of the most trusted, time-tested ingredients. Both are known for their ability to absorb excess oil, detox the skin, and treat breakouts—but which one is right for you?
Let’s break down their origins, benefits, differences, and best use cases so you can make the right choice for your skin type.
What is Bentonite Clay?
Bentonite clay is formed from volcanic ash and is rich in minerals like calcium, magnesium, and iron. It has strong negatively charged ions, which bind with positively charged toxins and impurities on the skin.
Often grey or cream in colour, bentonite clay is known for its deep-cleansing and detoxifying properties.
What is Multani Mitti?
Multani mitti, also called Fuller’s Earth, is a type of natural clay from India. It has been used in Ayurvedic and Unani systems of medicine for centuries. Known for its cooling, oil-absorbing, and exfoliating effects, it’s one of the most popular choices for acne-prone and oily skin.
It usually appears as a yellowish-beige powder with a smooth texture.
