To whom it may concern: I worked in cosmetic manufacturing for multiple natural, aluminum free deodorant brands and in all of my market research this is my favorite serum deodorant formula! In the process of developing an effective serum, AHA deodorant formula I examined almost every single option on the market and this is hands down my favorite. Efficacious, not sticky, no burning (alcohol %) and reasonable scent load (unlike Saltair). I appreciate this product!

Review specifically for the green tube "Serene Clean" version: My favorite deodorant for years now! I usually buy from Sephora's website but this was faster shipping. Put it on directly after bathing and drying off and it will WORK! Barely-there clean scent, almost fragrance free. Also love that it's clear so no marks on clothing!

I’ve struggled with underarm odor my entire life and this is the first aluminum-free, natural-ingredient deodorant that has truly worked for me. I’ve tried so many, and this one is hands down the best—I won’t use anything else. It has a very subtle scent, but what really impressed me is how effective it is: I only need to apply it a couple of times a week rather than daily like traditional deodorants. It goes on wet but dries quickly, which is a huge plus. I never write reviews but this deodorant was a life changer for me - buy it now!

This deodorant lasted pretty long but did let some of the smell through. For the price I’d expect 100% coverage value. The texture is very wet so it takes a second to dry. It’s pretty good, but Drunk Elephant’s Sweet Pitti is better

Ok, this is the best deodorant! I am a dental hygienist, which means I spend my days with my armpits very close to people's faces. It gets hot when you're wearing a mask, gown, gloves, etc. Top that off with occasional high levels of stress and stinky pits can happen. I used to have to keep deodorant in my bag to reapply. This the ONLY deodorant that goes all day long! I love that the green scent is so light it's barely detectable. The blue scent, however, is strong and unappealing. My biggest issue now is that the price has jumped to $20! It was $12 a few years ago, and I think it was $14 the last time I purchased (last year). I might just have to go back to using the old deodorant and reapplying because this is insanity.

I have been using this for a few years. Never a breakout and totally incredible odor control. I had been making my own deodorant for years to avoid the toxins, but my teenage daughter's pit smell was not possible to control with just my homemade concoction. We tried so many and while a couple were ok only one brand did not break her out and that had minimal effect on the odor. I had just given up and decided she'd either have to deal with trying to stay on top of the pit smell by wiping her pits throughout the day or use the harsh stuff, when I found Kosas. This stuff is absolutely incredible. I love roll-ons and so that was a bonus. Never in a million years did I think I'd find something like this. My daughter never smells and I have stopped making my own. Kind of pricey, but I will never change brands. My only fear is that if they ever stop selling this, I would be lost for an equal solution.

Works really well, the smell isn’t very fragrant so if you are loooking for that then this product is it. All natural ingredients, 24 hour protection against odor and the liquid dries down in less than a minute. Will be repurchasing.

Works really well, even in hot, humid weather. I had no issues transitioning to this from a typical antiperspirant/deodorant. I don’t tend to sweat a lot, which probably helps, but I can get stinky when I do, but this deodorant prevents that from happening and has since the first day I used it. I spend a decent amount of time in Hawaii, and so I have put this stuff to the test, and I have no complaints about its efficacy. I did take off one star for it being a roll-on. I don’t like the sticky feel. It’s no worse than any other roll-on, but I wish it were in a stick form.
