The exfoliating ingredient in the microdermabrasion is pumice, which is a mild and safe byproduct of bauxite, also known as aluminum silica. The aluminum component of this ingredient is very minor and does not absorb in the skin.

It is deemed safe by the FDA, Health Canada, Environmental Working Group (EWG), American Journal of Toxicology, Cosmetic Ingredient Review Board and Whole Foods.  

Because bauxite is the key exfoliant in this product, it is not possible to manufacture without it.
