The Kosasport Hot Body Team Set
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 used to bounce from Dove Clinical and Dove Spray and heard so much about all the bad chemicals.. switched to Native and other “natural” options but they all just masked the smell. Now THIS product was life changing. It actually treated my BO and now my sweat smells like Maple Syrup!!!!! like what?????!! so great 10/10 and it lasts so long !!

Since having my daughter a year and a half ago, I’ve been dealing with excessive pit sweat and BO. I’m sensitive to so many deodorants, and the ones that didn’t cause a rash weren’t cutting it anymore. It was embarrassing and affecting my day to day life. Literally within DAYS of using this product i am not sweaty or stinky. Like, I’m in shock. I still use my old deodorant during the day for now, but honestly i think i could skip it. BRB buying 100 tubes.

I have been trying countless aluminum free deodorants for the past THREE years trying to find a formulation that would work for me. Charcoal detox, nope, baking soda, nope, even spent a lot of money on Lume products, nope! FINALLY! Kosas came through with a winner. It actually freaking works. I could kiss your formulation team. It slides on wet, but dries quickly. Some may complain about texture, but honestly who cares. This product works!

Since having Covid my b.o has been unbearable. I don’t know what changed but I’ve literally tried every deodorant out there and none work. Until I bought this. I could actually cry because I had lost hope and figured I’d just be stinky forever. This deodorant is a godsend. I’ve been using a glycolic toner at night and this in the morning and there is ZERO smell. Nothing. Thank you!!
