Who should use it: Those with oily or acne-prone skin may find bentonite clay to be especially beneficial, though it can be too drying for those with dry or sensitive skin, says Fahs. How often can you use it: This depends on the product you're using and your particular skin type, though usually weekly.
Works well with: Jeffy says it can be used with a variety of different ingredients—including tea tree oil, apple cider vinegar, and turmeric, just to name a few—for synergistic effects. Don't use with: Since it can be drying in and of itself, be cautious about pairing it with other acne-fighting ingredients, such as acids or retinols, says Fahs. Well, for starters, it's not just any old type of clay.
Fun fact: While the original source of bentonite clay was the Montmorillon region of France, where it's been used on the skin for centuries, the term "bentonite" refers to the largest source of the clay today, Fort Benton, WY, she adds.
Field trip, anyone? To the point, bentonite clay has a long and storied history. It's the detoxifying properties that really are bentonite clay's calling card, but it can do more than just that. As far as side effects go, topical use of bentonite clay is much less likely to cause any safety issues than ingestion of the ingredient, says Jeffy. That being said, sensitivity or a reaction is always possible.
Do a small patch test on your inner forearm before applying all over your face, and if irritation occurs, discontinue use.
And, broadly speaking, bentonite clay is best reserved for those with oilier skin, as it can prove to be too drying for anyone who has a dryer complexion to begin with. There are plenty of products that contain bentonite clay, given that it does play nicely with a wide array of different ingredients. You can also easily purchase straight-up bentonite clay powder and go the DIY route, though Fahs warns that it's important to pay attention to what you're buying.
This is why although there are many ways to purchase bentonite clay powder in bulk for very cheap, one should tread carefully," she says. Do your research to find out where the clay is coming from, whether it's been checked for purity, etc. Both derms recommend this heavy-duty, pore cleansing mask. Also nice: It never gets super hard or cracked as it dries. One of Fahs's picks, this affordable mask pairs bentonite clay with kaolin clay another mineral-rich version for maximum purifying and oil absorption.
Bonus points for the fact that it's fragrance-free and hypoallergenic, a boon for those whose skin is both oily and on the sensitive side. If you're looking for straight-up bentonite clay because you want to take matters into your own hands, this is one of the most popular options out there, somewhat of a cult classic. FYI, the directions suggested mixing it with apple cider vinegar which makes for a less clumpy effect than if you mix it with water , which is fine, though Fahs notes that this can increase the likelihood of irritation, so proceed with caution.
There's also lactic acid in the mix for some gentle exfoliation, making this a great formula to reach for whenever your skin needs a little extra brightening boost. If you want to use bentonite clay as a strategic spot treatment rather than in a full face mask, try this guy. Creatinine is able to diffuse from the blood vessel to the intestine and be reabsorbed in the intestine. In experimental model of hypercreatininaemia in mouse, montmorillonite is reported to decrease serum creatinine by absorbing that in GI tract and accelerating its excretion from the intestine Urea is the primary metabolite derived from dietary protein and tissue protein turnover.
As kidney function decreases, the BUN blood urea nitrogen level rises. Bentonite is shown to promote the diffusion of urea from blood vessel to intestine, and inhibits the absorption of urea in intestine Then it sounds that bentonite might be beneficial in renal health.
The number of antibiotic-resistant pathogenic bacteria has substantially increased nowadays. This alarming trend implies the need to identify and assess new antibacterial agents. It is reported that natural geological minerals hold antibacterial properties, which might provide the hope for novel therapeutic compounds It was shown that montmorillonite is able to absorb coliphages T1 and T7 of Escherichia coli in vitro Some modified menmorillonits have also shown to exert antibacterial effect 48 — These antibacterial effects might result from physical interaction i.
It is shown that bentonite might modulate the immune response of body. Particles of bentonite inhibits lipopolysaccharide- or concanavalin A-induced red blood cell proliferation and antibody response in vitro It is reported that oral bentonite slightly decreases incorporation of calcium in the bones of goats In nutrient-deficient broiler chicks, although bentonite increased food intake, but did not compensate tibia calcium decrement Montmorillonite has been used as a drug delivery system for drugs used in cancer therapy such as Paclitaxel 54 , 5-fluorouracil 55 , 6-mercaptopurine Although a study reported the genotoxic effect of bentonite on human B lymphoblast cells 57 , recently bentonite has been shown to inhibit the growth of human cancer cell lines U central nervous system, glioblastoma.
It seems that bentonite clay surfaces controls the levels of metabolic growth components Montmorillonite is reported not only to adsorb thyroxin and triiodothyronine in vitro but also reduces these hormones in hyperthyroidism model mice. It prolongs the sleep time, improves the hypoxia tolerance capacity and reduces the spontaneous activities of those mice Bentonite is shown to decrease the bleeding and clotting time and therefore is suggested as a haemostatic agent 60 , It is also reported to act as a promising nanoscale size filler in food packaging industry Indoor volatile organic compounds VOCs have been assumed to affect human health.
VOCs can either originate from phenolic and benzene-like compounds in building materials and office furniture or from molds fungi growing inside improperly ventilated or sealed buildings.
Interestingly it is mentioned that volcanic materials, clays and minerals such as montmorillonite filter VOCs and thereby limit human exposure to these dangerous compounds Besides the above mentioned beneficial effect of bentonite, some unwanted effects are also reported.
In vitro studies have shown that bentonite increases cell lysis in some cellular lines while has no effect on some others 64 , A suspected case of bentonite poisoning was reported in a cat which was known to ingest bentonite-containing cat litter. This toxicity led to hypokalemia and hypochromic anemia presented with lethargy and muscle weakness In a 3-year-old girl treated with oral and rectal bentonite as a home remedy, severe hypokalemia occurred which might occur due to the gastrointestinal binding of essential electrolytes Generally it sounds that like any other drug, big doses of bentonite can have some side effects and thereby it is necessary to use a therapeutic dose of this mineral in diseases.
This article reviewed the papers related to the impact of bentonite on body health. It seems that bentonite, as an abundant natural element, holds the properties to be regarded as a therapy in a broad spectrum of disorders.
By searching between more than articles in Pubmed about bentonite clay, it was determined that about articles were related to the effect of bentonite on body function. The results, which were reviewed in this article, suggest that bentonite has enough encouraging characteristics to merit further investigation. Considering that Mother Nature has a cure for everything, the assessment of natural elements such as this clay should be considered in modern medicine.

Skin and hair For a long time bentonite has been used externally on skin. Gastrointestinal tract For a long bentonite was considered as a treatment of diarrhea. Kidney Creatinine is a breakdown product of creatine phosphate in muscle and its serum content is an important indicator of renal health as it is excreted by kidneys.
Antibacterial effects The number of antibiotic-resistant pathogenic bacteria has substantially increased nowadays. Bone It is reported that oral bentonite slightly decreases incorporation of calcium in the bones of goats Cancer Montmorillonite has been used as a drug delivery system for drugs used in cancer therapy such as Paclitaxel 54 , 5-fluorouracil 55 , 6-mercaptopurine 56 Although a study reported the genotoxic effect of bentonite on human B lymphoblast cells 57 , recently bentonite has been shown to inhibit the growth of human cancer cell lines U central nervous system, glioblastoma.
Other effects Montmorillonite is reported not only to adsorb thyroxin and triiodothyronine in vitro but also reduces these hormones in hyperthyroidism model mice.
It prolongs the sleep time, improves the hypoxia tolerance capacity and reduces the spontaneous activities of those mice 59 Bentonite is shown to decrease the bleeding and clotting time and therefore is suggested as a haemostatic agent 60 , It is also reported to act as a promising nanoscale size filler in food packaging industry 62 Indoor volatile organic compounds VOCs have been assumed to affect human health.
