It Works!
Making the switch to a non-toxic deodorant was a journey, but I’ve finally found one that is truly effective. I've been using a charcoal-based natural deodorant, likely similar to options from brands I'm interested in like Primally Pure, and the results have been fantastic. Initially, I was skeptical that a natural product could handle a full day, especially during workouts or hot weather. I am happy to report my fears were unfounded. This deodorant provides long-lasting protection and keeps me feeling fresh without any of the harsh chemicals, aluminum, or synthetic fragrances found in conventional antiperspirants. The transition period was minimal, and I've experienced zero irritation or rashes, which I've heard can be common with other natural alternatives. The scent is subtle and clean (I prefer the charcoal and essential oil options), not overpowering like some commercial brands. It applies smoothly, doesn't stain my clothes, and the peace of mind knowing I'm using a safe, healthy product for my body is invaluable. For anyone looking to make a healthier swap in their daily routine, I highly recommend finding a high-quality non-toxic deodorant like this one. It performs just as well, if not better, than anything I've used before.

Effective and not irritating
This is the only deodorant my daughter and I will use. She is extremely sensitive to fragrance and many ingredients in other deodorants. This product is very effective on underarm odor and doesn’t irritate our skin.

Best deodorant for that postpartum BO!
After having my 1st baby & dealing w the postpartum b.o to the point not one single deodorant would work for me anymore. I tried all kinds from natural to regular deodorant, mens even prescription deodorant literally nothing helped. I came across this after about a year of searching & it has seriously done wonders! After tonsss of research I learned bo comes from bacteria from the sweat. This deodorant is an aha & bha liquid roll on (aha/bha kills bacteria) so it prevents the smell it also helps with the sweat. And on top of that the ingredients lighten & brighten the skin so that’s a plus & it’s a cleaner brand of deodorant. It is also active ingredients so if you shave/wax wait a day in between because it will be red & irritated. It does take a few mins to dry & does have a light scent (even the fragrance free one) they all initially have the same scent the fragrance free one is a little more mild but it’s not bad. But overall 10/10 recommend

So far so good
I recently had a reaction and the skin in my armpits have been a bit dry and irritated when i used my standard deodorant/antiperspirant. I bought this to try it out for sensitive skin while moisturizing. So far it seems to work very well at suppressing body odors. I will need to agree with another reviewer... when putting on the product, it does have a weird smell to it when applying. It seems like after applying, to let the product air dry before putting a shirt on and going on with your day. After that, it seems like the product smell dissipates. It is quite pricey compared to the standard store bought products, but so far it works very well while not irritating my skin as my other deodorant/antiperspirant did. After a few more weeks of regular usage, if it still works very well, i think i may purchase some other fragrances as well.

Great Deodorant
I love this. I have sensitive armpits and I’ve been on the search for something clear, semi natural and fragrance free. This is it. It also lasts all day so I don’t have to reapply which is nice and if you deal with hyperpigmentation in that area, this will lighten your underarms overtime and help with that A LOT. My only con would be that it’s a bit wet and it doesn’t dry quickly so I have to wait before I can get dressed

It kinda works. Not super effective for men
I'm a guy who's trying to find a decent natural deodorant so I gave this unscented roll-on a try. And it does work under certain conditions. One of those conditions being that you don't sweat too much. In the winter if you wear warm clothing it will work for a few hours, but at around the 4 hour mark you'll notice a smell when you take off your sweater. It's a weird smell made up of your body odor and the strange, unpleasant smell of this "unscented" deodorant. So one pro is that it does work, but only for about 4 hours in my experience. The deodorant will leak out of the roller if you turn it upside down so it's best to shake the bottle with the cap on and then apply it to your underarm right side up. The cons are the very off putting smell of the unscented version, the price, and the information on the packaging is so small you need a microscope to read it.

Love it!
I've been using this deodorant for years and have no complaints! I love that its unscented and natural! I have sensitive skin just in general and haven't had any issues with break outs from it. Highly recommend!

Developed a rash after awhile. And roller ball sucks esp for a $16 deodorant!!!
I purchased this twice. It doesn’t last very long and at first it didn’t work at all. I stunk worse but then it seemed my body adjusted to it. After about 2 weeks I Finally started to like it and then the roller ball quit working And you have to squeeze it and it blows out everywhere. Then have to wipe it on with your fingers and are just wasting it. Hate that! But it was working for the BO and it was natural So I thought WTH I’ll give it another chance. Ordered another one before my other one was even gone… used it maybe 3 times and developed a bad rash in my armpits… it burns so bad! I’m not sensitive so no idea why it happened. Roller ball sucked on this one too. Will not buy again. when the rash happened I’m thinking of everything…. what could this be from. I’ve never had a rash in my armpit and nothing has changed…: Then I remembered reading reviews on this before purchasing. and I think 1 or 2 other ladies ended up developing rashes too after wearing it for some time. So weird!! And can’t believe the roller ball sucks on a $16 deodorant! I’ll be purchasing another brand from here on out.

Im glad i chose the unscented, but the consistency is watery and i might finish this one sooner... hope the brightening the skin claim is true, not seeing result yet, but overall its ok
