Alum Stone/Crystal Deodorants: Zero Waste Review

When it comes to personal hygiene, deodorant is a pretty essential thing to have. No matter where you live or how active you really are, one thing is for certain: you will sweat and it will smell. When researching sustainable and more natural alternatives to the common deodorants found in stores, one option kept popping up for me, and that was alum stones. I bought one and decided to give it a try. 

(For the next part of this review, I just want to point out that I will basically be using the terms “alum stone” and “crystal deodorant” interchangeably.)

An alum stone is a crystal deodorant that is made up of potassium alum, which is a natural mineral salt that has been shown to have the same properties of today’s deodorants. The big thing that I saw in my research was that these alum stones have been used in Asia for centuries and have been known to have hypoallergenic and antimicrobial properties. The way they work is that the potassium alum prevent the growth of the odor-causing bacteria on your skin. No bacteria equals no smell.  Some more of my research also found that alum stones are great for healing redness and knicks and cuts on the skin.Another big selling point for crystal deodorants is the fact that they are relatively cheap and also can last months longer than traditional stick deodorants. I also liked the fact that for this natural deodorant alternative, I didn’t have to go out and make a DIY version. 

I bought my crystal deodorant right after I ran out of my old deodorant stick. It came in the mail and the stone itself was just a little cube that fit in the palm of my hand. I looked up some recommendations on how best to use the crystal deodorant, and all I really found was that it was best to wait a bit in between switching from traditional deodorants to the crystal deodorant in order to give your body a detox from the chemicals that it was used to, and that it was best to use the crystal deodorant after showering. To use it, all I had to do was wet the stone and apply it to my underarms like I would a regular deodorant. 

The thing that I think threw me off the most about the alum stone was the fact that it didn’t even have a smell to it, so part of me felt like I wasn’t even wearing deodorant. But I kept up with it and applied it every time after I showered. I read some people experiencing a transition period where they found that they were sweating more after switching to the alum stone, but I think that mat be attributed to the fact that alum stones are a deodorant, not an antiperspirant, so they don’t actually stop you from sweating, just the smell. However, I think that I noticed when I sweat a lot more, but I have no way of knowing if that’s because I actually did sweat more, or just because my subconscious knew that I was switching products and therefore made me more aware of my sweating. 

Overall, I would say that I did notice a reduction in the smell of my sweat after about a month of using the alum stone every night after showering. It wasn’t a hard switch to make since I already applied my traditional deodorant every day to begin with. The biggest habit change that I think I had to make was actively remembering that I had to wet the crystal before applying it to my underarms.  I will note that I have stopped using the alum stone, but only because I was curious in trying a brand that boasts to have an all natural deodorant. When I’m finished with trying out that product, I think that I will definitely be switching back to the alum stone due to the price difference and also personal preference.

I honestly wasn’t expecting to like the crystal deodorant as much as I did, and I also wasn’t expecting it to work for me as well as it did. When I was looking at reviews for people’s opinions on how the crystal deodorant worked for them, there were a lot of people that it worked for, but also an equal number of people that it didn’t work for. Because of that, I don’t feel like this is the best product to recommend for you to go out and buy just because it worked for me.

It’s hard when writing these reviews sometimes, because a lot of times I have to remember that not everything that works for me will work for other people, and part of me just doesn’t feel right endorsing a product that isn’t one-size-fits-all. Especially when it comes to personal hygiene, I know that it can be hard to find something that works for everyone and sometimes there really is only one product that works for someone due to other conditions. That’s why I never try to make it seem that a product that isn’t completely zero waste is bad. Because I know that there are people who do not have the same luxuries as I do.
