Nonallergenic, non sticky,
If you are allergic to regular deodorants, like I am, try this one! which is unscented. It also will last for a couple days if you are not out in the heat of very active. Very slight smell when wet and drying after that none.

Kill bacteria, gentle, I'm not allergic and works much better than Lume stick.
So much better than Lume than only lasted 3 or 4 hours. This has Alphahydroxy acid that kills the bacteria. I use to buy Yves Rochet hamamelis which would last 24 hours, but they stopped making it. This one lasts about 12 to 15 hours. It's great compared to lame Lume stick; I heard the cream Lume is better than the stick. . Kosas comes in a tube with a roll on and I don't stick anymore. YAY. .

Finally!!!
Finally a natural deodorant that works, doesn't stain my clothes, doesn't leave a weird film, and doesn't have a strange odor! Thank you, Kosas! This product is great! Over the past 8 or so years, I have tried no less than 15 different natural deodorants, ranging from inexpensive drugstore brands to more expensive specialty brands - minerals, magnesium, coconut oil, other AHA products, etc. in every form from solid crystals to liquids to yucky sticks. If you've tried a product in your search for a natural deodorant that effectively eliminates odor, then I have probably tried it, too, and been disappointed. I purchased Kosasport Unscented several months ago and have been completely satisfied. For me, it actually controls odor and lasts all day and beyond. It is a liquid roll-on, so it does require drying time, but it dries clear, odorless, and without irritation or dryness. It does not leave a tacky or messy film, and it does not stain clothes. After years of searching for an effective product, I am completely satisfied and have ordered more.For others who have been disappointed with the recent influx of coconut oil and magnesium based products that seemed like they were going to be "the one," and have, like myself, recently discovered the AHA and/or pH lines of products, I did try Lume first. It worked better than most, but it still had some negatives for me. I did a little more searching and found Kosasport, and I am so glad I tried "just one more." If you have had difficulty finding a natural deodorant that works for you, then I highly recommend trying Kosasport.

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.

Make the switch you need this
Never thought I’d switch from an antiperspirant. But this stuff has been a game changer. It really does eliminate odor. It has been effective on hot summer days, working out and even into the next day without a reapplication. Love the no scent.

Best aluminum-free and baking soda-free deodorant out there!!
This is a re-purchase for me and will continue to be!! Yes, it is pricey, but the item lasted me for 3 months. Last time I purchased the beachy clean scent, but this time I chose fragrance-free. Even the scented ones don't really smell like anything, so I thought I'd get fragrance-free and it's better for you if you have sensitive skin. This is not an anti-perspirant, so it does not make you stop from sweating. It makes your sweat smell like nothing, so you have no body odor. My only qualm with this product is that after 24 hours, my natural body odor will come back if not reapplied, but this happens with every aluminum-free deodorant for me.

Smells bad
I was so excited to try this deodorant because of all the glowing reviews I’ve seen about it and this one video that convinced me to buy. But when I got it, I was extremely unimpressed. This deodorant is supposed to be fragrance free, but it still has a nasty foul smelling odor. I wouldn’t recommend anyone by this and it claims to not leave any stains. But it definitely has left wet marks in my shirt because the deodorant stays wet for so long.

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.
