Spotlight On Bentonite

skincare benefits of bentonite for oily skin

You know what they say, one person’s trash is another person’s treasure.

Case in point: bentonite clay. If your skin’s as dry as the Sahara, you want to run in the opposite direction. This stuff will only make you flake more.

But if your skin’s as oily as a frying pan? Then, bentonite becomes your BFF. It’ll help you soak up the oil and keep breakouts at bay.

Curious to know why bentonite is so biased towards oily skin? Read on to find out:

What The Heck Is bentonite clay?

Bentonite is an absorbent impure clay made up mostly of montmorillonite.

There are different types of bentonite. Each one owes its name to its dominant element, such as potassium, sodium, and calcium.

Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. But bentonite can describe clay beds of uncertain origin, too.

Fun fact: bentonite was named by Wilbur C. Knight in 1898, after the Cretaceous Benton Shale near Rock River in Wyoming,

Bentonite has excellent absorbent properties

Have you noticed bentonite is used mostly in clay masks for oily skin? That’s because it’s super absorbent: it can soak up excess oil, shine and impurities from the skin.

Bentonite is what scientists use to determine how much sebum patients with inflammatory acne have. They put bentonite on the skin and, a few minutes later, remove it and measure how much oil the clay absorbed (in case you’re wondering, people with acne produce 3 times more sebum than normal).

Once that oil is out of the way, you won’t look like you have a giant frying pan where your head is supposed to be. Plus, that excess oil can’t accumulate in the pores and clog them anymore. Bye bye breakouts!

Bentonite is also said to be able to draw toxins and impurities out of the skin. I admit I was sceptical. Surely, brands would say anything to get us to buy it?

But when I dug deeper, I found there’s some truth in this claim. Turns out, the army has been testing absorbing agents including bentonite for the “decontamination of supertoxic lethal chemical warfare agents on skin” with promising results.

Still, when it comes to detoxification, it’s your liver and kidneys that do most of the job, so don’t rely on bentonite too much.

Does bentonite clay have any side effects?

Bentonite’s job is to soak up excess sebum. Sebum is simply your skin’s natural moisturiser.

If your skin pumps out more sebum than it needs, bentonite will come to your rescue by getting rid of the excess.

But if your skin is dry and doesn’t pump out enough sebum to  stay naturally moisturized? You don’t want bentonite to soak up the little your skin produces. It’s a recipe for dryness and flakiness.

What are the best skincare products with bentonite?

The Bottom Line

Bentonite’s soaking properties make it oily skin’s BFF and dry skin’s arch enemy. Use it carefully!

I have some Paulas Choice products in the mail on their way to me and I have chosen the Hydralight products instead. I haven’t bought a mask, so I will keep the one you recommend in mind!

Tirurit, let me know how you like her. I love her line. So far, none of her products have disappointed me.

You know, I tried that mask from Paula’s Choice and it stung my face like crazy! I guess my skin is too sensitive for it. I’m glad it works well for you, though.

Laurie, I’m sorry you had such a horrible reaction to it. I guess it’s too potent for sensitive skin. Mine is combination and can take pretty much anything, bar a few comedogenic ingredients.

Anubhuti, if you have oily skin, you’ll love it.

Niesha, they do indeed.

Ooo I didn’t know this one! I usually think of kaolin clay for oil-reducing. Superb post! Happy New Year, Gio!!

Gio January 8, 2015 - 3:15 pm

Janessa, kaolin clay is very good for oil reduction too. Thanks! Happy New Year to you too!

Seeing this I cannot resist sharing that apparently kitty litter (without scent) contains bentonite and can be used…. as a mask! You might read this and then go crazy thinking “what is this girl talking about!?” I´ll attach you the link where I found the video.

Barbara, that’s exactly what I was thinking. People are crazy. I think I’ll keep getting my dose of bentonite from facial masks. But thanks for sharing the link. It’s very interesting indeed.

Hi Gio!
I am wondering if it is safe to use bentonite powder as a sheer powder for oily skin? Any thoughts on leaving a bit of the clay on your skin for a long period of time?
Furthermore, would it help with oily hair? How can I use it as a mask?
Thank you so much for your website! It is really wonderful!

Hi Denise, as far as I know, bentonite should always be removed after a few minutes. And yes, it works well for oily hair. Just mix bentonite with water, let it settle for a few hours and shake it up. Even so, some of the clay will settle. Don’t use that bit.
