    KosasSport Chemistry AHA Serum Deodorant



    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.


    Key Ingredients:

    AHA Blend:

    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

    • This is a clean light weight serum deodorant that dries quickly and doesn't leave a residue on your clothes.

    Best clean deo out there!

    I am absolutely in love with this clean deodorant! I was hesitant at first because it really doesn’t have a smell, even the scented one has only a slight scent. But it is amazing. It really protects against odor. I’ve worked out with it on and there was no odor. I’ve also broken out under my arms from trying other clean deodorants and had a lot of dark spots under my arms. The dark spots have cleared up immensely with just two weeks of wearing it. I have been so insecure about the scarring under my armpits and they’re finally starting to look normal again. Thank you thank you!!

    Kosas Sport deodorant

    seems ok i dont use it everyday but it seems better than most

    This is the best deodorant I've found

    I really like this! It is the only one that beat the stink for longer than 2 hours. I still have to apply but I wasn't applying it every 2 hours. I applied about every 6-7 hours


    I was not letting myself get too excited about this before it came because I have tried many "natural/clean" deodorant's before and they didn't work. But this does and it is AWESOME!. I am allergic to baking soda (after the 3rd underarm rash from natural deo I figured that one out!!) so when I saw this did not have baking soda I was cautiously hopeful. This works GREAT, feels nice going on, doesn't leave a film, and best of all stops the stink!! I could not ask for anything more!!!!

    Best Natural Deodorant

    I have tried so many natural deodorants only to be disappointed...either they didn’t work or would cause skin irritation.
    This deodorant has been amazing. No adjustment period needed.
    Works great- even after tough sweaty workouts and is so easy to apply.
    Finally found a healthy product that actually works.
