The deodorant crystal our customers are raving about!
The alum stone is a simple and effective natural deodorant that can also be used as an aftershave. It's a mineral salt, so it stops odor producing bacteria from forming, making it a safe and effective natural deodorant.
Each alum stone is a unique mineral crystal with slight variations in shape and appearance. They are natural, hypoallergenic, cruelty-free and vegan.
When used as an aftershave, it soothes nicks and cuts, and helps to prevent razor burn or skin irritation from shaving.
Alum stones will help you sweat less, but they aren't an antiperspirant meaning they don't block your body from releasing toxins or cooling down. They are a nontoxic, beautiful and package free alternative to deodorant.
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 to dry if needed and store somewhere dry.
It does not expire, nor is it temperature sensitive. With daily use, this stone should last over a year.
Classic - Each alum stone is a unique mineral crystal with slight variations in shape and appearance.
Imperfect - 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 - 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 should last around 2 years. You’ll end up with a small piece that is 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 so skeptical about these even with so many good reviews mainly because it seems very new-agey - like some special crystal that will magically make you not smell bad (lol) but I swear it works so well. I’ve used so many natural deodorants and have always been disappointed but the Alum Stone is just as good if not better than any non-natural deodorant I’ve tried. I also work out a lot (running and/or biking) 5/6 days per week and it even protects me through workouts! Highly recommend. (Plus it’s really pretty)
Absolutely love this product. I have extremely sensitive skin and a lot of deodorants sting or have contributed to rashes and darkened my underarms. I stopped using them almost half a decade ago and switched to alum. However sourcing the right kind of alum that didn't make your underarms sticky was dufficult. So glad to find eco-collective. The stone is magical. It is gentle on my underarms and my underarms don't smell, at all. And this is without deodrant or perfume.
I’m not a super smelly person, but I’ve had a lot of deodorants mix with my natural scent weird (mainly natural deodorants) or give me rashes because my skin is really sensitive- I’ve only use this for about 3 days but honestly I’m so impressed and surprised! This is definitely my favorite low waste swap this far, I HIGHLY recommend getting the alum stone! The shop was able to get it to me so fast and it was also packaged with care :)
I've tried a few different brands and nothing seemed to work well...half way through the day needing to reapply. Totally different story with my new alum stone. Apply once and I'm good all day. In fact, I tend to shower only every other day and I've still had good results without even reapplying for the second day. It's that good! I love that it came without any packaging at all and it seems like it's going to last quite a long time.
Just like everyone else, I was skeptical at how this could possibly work. But I gave it a try anyway. I couldn't find a natural deoderant that worked for me and I'm so glad I found this. Not only is it pretty but it worked perfectly and it's plastic free! I'm so glad I no longer need to shop for deoderant for a long time. Thanks eco collective!
