    KosasSport Chemistry AHA Serum Deodorant

    Scent

    DETAILS:

    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

    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.

    New formula?

    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…

    Whoa wtf?!

    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!

    It’s ok

    I’m not sure how effective it is from protecting against smells. Also I wasn’t super fond of the smell of the product itself.

    Love love

    Love how easily it goes on, smell, texture. My only thing is if you sweat like I do the scented version feels needed haha.
