Kosas Sport Chemistry AHA Serum Deodorant (Fragrance Free)

Im glad i chose the unscented, but the consistency is watery and i might finish this one sooner... hope the brightening the skin claim is true, not seeing result yet, but overall its ok

The scent of the blue option is not great. Very chemical and overpowering. I’ve tried the white one and it’s much better.

Does not work

I had to return it as it was an opened package received. The fact that I was unable to use it disappointed me, even though I was eager to use and review it.

Kosas Chemistry is the best! Works great, feels fresh, and super gentle.

To whom it may concern: I worked in cosmetic manufacturing for multiple natural, aluminum free deodorant brands and in all of my market research this is my favorite serum deodorant formula! In the process of developing an effective serum, AHA deodorant formula I examined almost every single option on the market and this is hands down my favorite. Efficacious, not sticky, no burning (alcohol %) and reasonable scent load (unlike Saltair). I appreciate this product!

Making the switch to a non-toxic deodorant was a journey, but I’ve finally found one that is truly effective. I've been using a charcoal-based natural deodorant, likely similar to options from brands I'm interested in like Primally Pure, and the results have been fantastic. Initially, I was skeptical that a natural product could handle a full day, especially during workouts or hot weather. I am happy to report my fears were unfounded. This deodorant provides long-lasting protection and keeps me feeling fresh without any of the harsh chemicals, aluminum, or synthetic fragrances found in conventional antiperspirants. The transition period was minimal, and I've experienced zero irritation or rashes, which I've heard can be common with other natural alternatives. The scent is subtle and clean (I prefer the charcoal and essential oil options), not overpowering like some commercial brands. It applies smoothly, doesn't stain my clothes, and the peace of mind knowing I'm using a safe, healthy product for my body is invaluable. For anyone looking to make a healthier swap in their daily routine, I highly recommend finding a high-quality non-toxic deodorant like this one. It performs just as well, if not better, than anything I've used before.

حلوووو مره مشكلته الوحيدة انه يطول على ماينشف لانه رول سايل وريحته مش ولا بد بس على الجسم حلو جدًا ماله ريحة ولا لون مزعج ومفعوله يستمر مدة طويلة انصح بإستخدامه

رائع فقط التدفق جدا كثير يمنع الرائحه وسهل الاستخدام لكن لابد من اعادة تطبيقه مرة اخرى خلال اليوم إذا كنت تعاني من شدة التعرق

Works really well, the smell isn’t very fragrant so if you are loooking for that then this product is it. All natural ingredients, 24 hour protection against odor and the liquid dries down in less than a minute. Will be repurchasing.
