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

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…
Look, I decided to switch deos bc the natural one I've been wearing for 5 years started to fail. There is literally nothing worse than sitting down in a work meeting and realizing you can smell yourself. IG, being the omniscient presence it is, seemed to know my very thoughts and presented me with a kosas ad. Everyone seemed to love it so...why not? Well...ho...ly....eff. I have been using this deo for a week and even after 48 hours without a shower on one occasion...zero fails! I'm not even an influencer but if you want to pay me to promote this product, I will. @truly_alive on IG!
I have loved everything I have used from Osea, and this is no exception. Goes on nicely, not greasy, makes skin feel soft. I haven't used it long enough to see any changes (just a week), but I am sure it is working!
I have tried them all and always come back to this mascara. No clumping, no flaking, no eye irritation. Lengthening and thickening at the same time. Lasts a long time in comparison to others. Good price point.
A friend suggested I stop in for new makeup. I followed her advice and was so excited fo have a tutorial on how to apply the products. These products are not only perfect for my skin, but I feel safe using them. I have two teens and plan to bring them in so they can use safe products that are not damaging to your skin.
