Bentonite Clay vs. Fuller’s Earth Clay

Bentonite Clay (Buy Now)

One of the most popular, abundant and powerful healing clays is bentonite, which is composed of naturally occurring weathered and aged volcanic ash sediments. This highly absorbent swelling clay has a high percentage of montmorillonite (at least 30%), which gives it its extraordinary powers. Bentonite draws out oil and impurities, unclogs and shrinks pores, and heals acne while tightening and toning skin. When mixed with liquid (like clean water or apple cider vinegar), bentonite swells open like a porous sponge, drawing out toxins, oil, excess sebum, bacteria and fungus through electrical attraction. Its impurity-absorbing abilities make it ideal for oily, congested and acne-prone skin types, as well as those struggling with psoriasis and eczema. Bentonite is commonly used in over-the-counter acne treatments, bath soaks, foot, body and face masks.
