      This stuff is AMAZING! Even after running around and sweating I have NO odor, and I usually am pretty stinky.

      I have no smell in my armpits whatsoever. Even when I exercise! I keep checking with a sniff test and literally there is no smell!!

      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.

          Frequently Asked Questions

          You've got questions, we've got answers

          What is Chemistry?

          Chemistry is a clean, stain-free serum deodorant that features a unique AHA blend for the ultimate odor-fighting treatment. Bonus: Soothes skin, visibly brightens, and helps prevent ingrown hairs.

          What does it do?

          Chemistry is a different approach to BO - we don’t just want to mask smell, we want to treat it where it starts. Our specific AHA blend helps create a pH environment where odor-causing bacteria can’t survive - leaving you feeling fresh, clean, and ready for anything.

          How does it act like skincare?

          Our deodorant does more: the AHA blend keeps you from smelling, but it also visibly brightens the darker underarm area and helps with ingrown hairs. No aluminum. No baking soda. Only skin-nourishing ingredients allowed.

          What makes Chemistry different from other clean deodorants?

          Chemistry is a 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.

          How do I apply?

          Shake, roll, and go - easy! Gently squeeze for more serum.

          How long is the wear?

          24-hour wear - we like to say it lasts from shower to shower.

          Customers say this deodorant effectively controls odor throughout the day, even during intense workouts and hot weather. Many note it dries quickly and doesn't leave marks on clothes. While some praise its gentle formula, others mention experiencing skin irritation or rashes. Common feedback includes requests for a travel-size version. Reviews indicate it allows natural sweating while managing odor. Some users mention it feels slightly sticky upon application, and a few note the roller ball dispenser could be improved.

            Fourth restock

            I figure it time to write a review. About four years ago I bought one deodorant and my life has never been the same!( it might sound dramatic but I beg to differ) I grew up trying all the deodorant, so many but still was looking for one that worked! I was so done with my men’s aluminum filled deodorant stick as a high school girl trying to find a cleaner option. my goal was to find a deodorant that was a no brainer works great and not powdery. I was done with the fuss! In 2020 the Kosas chemistry deodorant released I was so doubtful. As a huge fan of Kosas makeup I would see it all the time and I eventually did research on it and I was impressed this bad boy was clean, liquid, all day wear, no residue… obviously it dosent work how can it have that many claims? Well when you’re desperate you’ll try it, so I bought it. It took me a week to adjust but ever since I use it every day. It’s a no brainer. I don’t skink and I’m done shopping around trying new ones. I actually forgot it one on vacation once and I bought one from Whole Foods it was bad it felt like sand paper and it didn’t work. One thing I do before I use this deoterant is make sure my armpits are clean either shower or wipe it with a washcloth and soap, apply deodorant and your set all day! Also I shop on Black Friday and stock up for the year that’s my fav tip. Big thank you to Kosas you guys are the best! I also love your setting powder, concealer, face sprays ugh my makeup case and skincare cabinet are big fans!…

            This product actually works Yay!

            This product actually really works not only to help keep any unwanted odors away, but it doesn’t leave any white or gross residue under my armpits or on my clothes and it does not irritate my sensitive skin, which is also super important overall I think this is a great product, so keep making it

            Rebuy FOREVER

            This is the best deodorant of all time!!! I don’t stink, ever with this deo. I even was a bridesmaid this end of summer-SUPER hot and was a bit self conscious of not switching back to aluminum Deo but I had my friend smell test me and even she swears up and down I had 0 armpit odor. This stuff is legit!!! I love the serene clean scent over the beachy one. Only downside is that Kosas subscription doesn’t have a 1 monthly frequency option, only 2,3, or 4 months and I always run out righttttttt at the end of the 2 months when I’m waiting for the package so I have to order from Amazon which I don’t prefer to do at all. Consider giving more frequency options! Otherwise a great product!! Never everrrrrr discontinue it please!
