      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

            Awesome

            After using a natural deodorant which was discontinued, I did some research and Kosas came up in the blogs. I had never tried a liquid or gel version of natural deodorant and didn’t know what to expect. However, Kosas really did deliver and this stuff is amazing. My darker underarms lightened, little to no razor bumps, and one application lasted me throughout working hours. Towards the end of my first bottle I wasn’t sure how well it was still working but I could be at fault as it was a few months beyond the 12 month “good till” recommendation.

            At this point I decided to venture and try the Salt & Stone brand with their heavy marketing. While I did like their scent options, I had to keep reapplying their deodorant throughout the day and my dark underarms and razor bumps came back. What is worse, is my body started sweating even more, similar to the detox period when one comes off regular deodorant to natural which I felt really odd considering it WAS a natural brand. So now I have come back to Kosas and couldn’t happier. I will just make sure to watch the expiration date, but one bottle really does last me at least a year.

            I’ve tried both scents and probably prefer the Serene Clean with the calming Vetiver and Ylang Ylang qualities vs the Beachy had maybe just a hint too much vanilla for me.

            I’ve never had a weird reaction some people on here have but occasionally a small sting if putting on freshly shaved skin. They do have a notice about sun exposure and possibly it could…

            Nice deodorant

            I think it works but I haven’t worn it enough to make a good judgement.

            Deletes smell

            This is exactly what I wanted, something that dries down to being imperceptible, and that doesn’t have added fragrance. I apply it right after I shower, and it works 10/10 perfectly for me. Highly recommend!
