A clean, stain-free deodorant with a unique blend of AHAs for the ultimate BO-fighting treatment. Bonus points: soothes skin, visibly brightens, and helps prevent ingrown hairs. No aluminum. No baking soda.
What it does:
Different approach to BO: We don’t just want to mask smell, we want to address it where it starts. Our specific AHA blend helps create a pH environment where it’s harder for odor-causing bacteria to survive—leaving you feeling fresh, clean, and ready for anything.
Deodorant for skincare freaks: Our deodorant does more: The AHA blend keeps you from smelling, but it also visibly brightens the darker under arm area and helps with ingrown hairs. No aluminum. No baking soda. Only skin-nourishing ingredients allowed.
Clean deodorant that isn’t annoying: The thin, non-sticky serum dries quickly and doesn’t leave a residue or stain on your clothing. The cooling roller ball is so easy and it actually feels good going on your skin.
Shikimic Acid: A natural deodorizer derived from star anise, known for antimicrobial properties + naturally helps minimize odor
Mandelic Acid: Helps address dullness and discoloration, derived from bitter almonds
Lactic Acid: Exfoliates while helping to improve the skin’s natural moisture factor
Aloe Vera Juice: A potent moisturizer that invigorates and helps soothe the skin
Hyaluronic Acid: Hydrates, softens and smoothes the skin

Works great as an exfoliator/treatment, slight rash
I have mixed feelings on this deodorant. When I apply it, I do not have a rash on my actual armpit, but for about 30 minutes post application, I have a red halo on the skin around my armpit. It disappears fully until the next application. It works to reduce odor for at least a few hours. I would not rely on this for a hot summer day out in public, nor would I rely on this at the gym. I think this is great to use as a base deodorant for the day, and then use a more concentrated one later for the gym. I would use this deodorant if wearing an important or delicate outfit that cannot risk a deodorant stain. The thing I really like about this deodorant is that it really conditioned my armpits like an exfoliator or treatment. All of those little shave bumps disappear. My armpits are soft, smooth, and the skin is bright. I didn't notice it when I was using it, but I noticed it when I switched to a different product afterwards.
I switched from Humble deodorant to Kosas about a month ago and will never go back (I’ve also used Agent Nateur as well). Kosas is hands down the best and most effective for smell (I still sweat but not a ton that doesn’t really bother me). Ten out of ten would recommend and will purchase again!
I am impressed about this product. It works well throughout the day even this summer! And the packaging is super convenient.
Didn’t work for me at all
I tried it a few times, and found I actually smelled like worse BO than I’ve had before. I tried using different amounts, putting it on at different times of day, and reapplying. Each time I could smell the BO after a short time. I really wanted it to work.

I’ve been using this for over a year with no negative effects, but the newest tube I purchased has been giving me a rash around my underarms. Similar to what happens when I use a formula with baking soda. Not sure if I will repurchase in the future, hopefully it stops irritating my skin…
