Bentonite clay is a natural clay with a fine, soft texture. It forms a paste when mixed with water. Some people use this paste for medical or cosmetic benefits, such as treating rashes and acne or as a hair mask.
People have used bentonite clay to remove impurities on the skin, such as oils, and toxins from the body for thousands of years.
Bentonite clay is present in many skin products, but some people also add it to foods or drinks with the aim of relieving digestive issues or removing toxins from the body.
