Tea Tree Twist, Cambrian & Mint, Mother Earth, and Lavender Lemon organic soaps have all been made with the addition of earth clay's, revered for their ability to aid in removing toxins from the skin. French green clay and bentonite are one in the same (montimorillonite). They are both used by natural cosmetic companies in masks, soaps, and powders. The same is true for kaolin and cambrian clay's. With the addition of organic oils and butters, these clay's can pull unwanted toxins from the skin, yet leave it feeling soft and clean. I highly recommend these soaps for anyone with problem skin which may include acne, aged, psoriasis, itchy skin, or anyone who just wants to give it a try!
