Different Approach To BO
We want to treat BO where it starts. Our blend of AHAs (Alpha Hydroxy Acids) helps lower the pH in your pit so it’s harder for odor-causing bacteria to live there. Less bacteria = less smell.
Deodorant For Skincare Freaks
The AHA blend also brightens and exfoliates to help prevent uncomfy ingrown hairs. Additional skincare ingredients work to moisturize and soothe the sensitive skin of your pit too.
Clean Deodorant That Isn’t Annoying
The lightweight serum dries quickly and doesn’t leave a residue or stain on your clothes. The cooling roller ball is also super easy and feels sooo good going on your skin.
Kosas Clean
Vegan, cruelty-free, and gluten-free. Formulated without: aluminum, baking soda, mineral oil, talc, silicones, fragrance, parabens, sulfates, and phthalates.

I have to applaud your formula. I have tried so many products at wide price ranges and manufacturers from France, Korea and Japan including the USA. This is by far the best deodorant that works for me. I have recommended it to everyone. I’m not an influencer but as someone with hyperpigmentation with scarring, highly sensitive skin as well as needing a strong product postpartum, this Kosas deodorant protects my skin barrier and noticeably works. My friend going through menopause feels the same way. I’ve turned all my girlfriends onto it.
Competitors like Lume or House of Balance have given me rashes so I would waste my cash, or ones mainstream are more scent-masking and will not effectively treat body odor so if I miss an application unwanted smells would come back just as strong. I could tell the efficacy of this Kosas formula is targeted toward minimizing odor bacteria because if I forget to apply for a day like if I am extremely busy, I still smell nice.
Thank you for making your product. I can’t wait until my haul comes in the mail!
Please make travel sizes and perhaps a better applicator like a pump—not a rollerball. I would prefer to be able to apply it without touching the applicator to my skin.

This is the only non-aluminum deodorant that hasn't given me a rash. Doesn't stop sweating, but it Definitely stops smell. My only disappointment is that despite begging for years, Kosas refuses to sell small travel-size versions of Chemistry Deodorant individually; you have to buy them as part of an expensive set with a bunch of other products. I wish I could just buy a travel-size version individually, I'd buy so many!

So I have been on the hunt for years to find something like this. It is AMAZING. SO AMAZING I have it on subscription which I rarely do unless a product is really really trustworthy for me. I’ve been trying to really lock down on not overbuying and using everything till the last drop and this is one of them. I see in some reviews they had a rash- here’s my tip- detox your pits before switching. You will 10000% have a reaction if you haven’t detoxed them. This happened to my girlfriend and I made her do an Aztec clay mask mixed with water and apple cider vinegar on her pits and wash with antibacterial soap then she had no issues. I 100% love this stuff and am in awe at how well it really does keep any smell away. Of course, you have to reapply daily if you are prone to stink but wow even a day and a half - no smell.
To the Kosas’ team- my only feedback is that when the product runs low the roller ball doesn’t work well and I have to cut open the top and apply with a cotton round bc I don’t want to waste anything.
