The deodorant crystal our customers are raving about!
The alum stone is a highly unique natural deodorant that can also be used as an aftershave. This amazing crystal deodorant is made of mineral salt, so it stops odor-producing bacteria from forming, making it a safe and effective natural deodorant. Each stone will last you for several years!
Alum stones will help you sweat less, but they don't block your pores like an antiperspirant would, meaning they still allow your body to naturally cool down and release toxins when it needs to. They are a beautiful and package free alternative to deodorant that's completely nontoxic.
Alum stones have been used since antiquity as a styptic and a deodorizer. The secret to using this crystal as a deodorant is to have clean skin before you apply! You can read more about how to use alum stones on our blog. When used as an aftershave on the legs or face, it soothes nicks and cuts, and helps to prevent razor burn or skin irritation from shaving.
Each alum stone is a unique mineral crystal with slight variations in shape and appearance. They are natural, hypoallergenic, cruelty-free and vegan.
Use and care
Gently wet the surface and apply as you would deodorant.
The alum stone works best when your pores are clean and open, such as after a shower. You can also use a warm or soapy washcloth to cleanse your underarm, and then apply the stone. Either works just fine! Cleansing your underarm first is the trick to what makes this so effective.
It can have a bit of an adjustment period like any natural deodorant. We suggest giving the detox phase a few weeks for it to work its best.
Please note: It is a salt crystal that dissolves with moisture, so pat dry if needed and store in a dry place. We recommend using an old jar lid as a tray for your alum stone!
It does not expire, nor is it temperature sensitive. With daily use, this stone should last over two years.
Classic - Each alum stone is a unique mineral crystal with slight variations in shape and appearance.
Imperfect (not currently available) - We inspect each stone from our manufacturer and have discounted some due to more noticeable imperfections. "Imperfect" alum stones are not broken, they are typically just slightly chipped around the edges, but work just as well!
Travel/sample size (not currently available) - This is a perfect way to sample an alum stone if you're unsure, or just want a smaller piece for travel. These are pieces of stones that were broken during shipment, so putting these to use is truly zero waste! Each has a smooth outer side that can glide against your skin.
This stone weighs 5.3 oz.
Potassium Alum (Mineral Salts).
Alum stones contain a naturally occurring form of aluminum (Potassium Alum) that does not possess the same health risks as the aluminums in many antiperspirant deodorants (Aluminum Chloride/Chlorohydrate/Zirconium), which block sweat ducts and glands. Potassium Alum is a different chemical compound and stays on the surface of your skin, making alum stones safe to use.
Does not contain Parabens.
Made in France.
End of life
Use until it’s too small to hold. It can last about 5 years, depending on how often you use it. You’ll end up with a small piece that's basically a rock, so you won’t want to put it in a compost bin but what you can do is sand it into a powder (it’s a very soft crystal), add water and put it in a spray bottle to keep using as deodorant! Zero waste!
I was skeptical about replacing my standard deodorant with this, but it really works! I'm thrilled!
my underarms have always been extremely sensitive to the point where even natural deodorants constantly broke me out in a rash AND made them dark! I’ve found one that worked a little but it did NOTHING for odor - if anything I think it made it worse! But on the first use with this, NO SMELL ALL DAY! Like wow - a week into using it and no rash either. Never thought a rock would be the answer to my sensitive underarms
This stone is like magic to me! I am an extremely active individual and the deodorant stone held up against my sweaty post run-pits. I spray my stone with water infused with essential oils to give my underarms a nice fragrance. I also sewed a little pouch out of repurposed fabric to keep my stone and spray bottle in while traveling. I highly recommend switching to this zero waste alternative!! Thank you eco-collective for introducing me to such a fabulous product!
I have been on the lookout for a packaging-free deodorant for a while and this is perfect! I've been using a variety of natural (homemade and store-bought) deodorants for the past six years. There is the detox period but I don't mind it. Thanks for offering this option!
I have used this product for several days now and am loving it! It goes on so smooth when I wet it a little in my sink.
I would compare it’s effectiveness to other natural aluminum free deodorants and have not noticed any BO smell, I am a recreational athlete so this is important! It won’t keep you from sweating but neither do any of the other natural deodorants. Best of all this is plastic free!!
