Pairs Best With
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.

I'm a dental hygienist, so I work all day with my armpits very close to people's faces. This is the only deodorant that works for me all day long, even through stress sweat! Natural deodorants worked well for me for decades, but then I got into perimenopause and they weren't enough. I'd have to reapply at lunch time and I'd still be concerned about smelling. One other popular (and odd smelling) chemistry deodorant worked well for 2 months, then just stopped. I've used this deodorant only for over 2 years now and it never lets me down. It also doesn't give me a rash and doesn't leave oily stains or white marks on my clothes. The only bummer is that the price keeps creeping up. I can't believe I'm spending almost $20 for deodorant.

The BEST DEODORANT EVER.
I am the stinky kid. About 15 yrs ago I stopped using anti-perspirant, b/c it was staining my armpits and causing all kinds of rashes and irritation. Since then it's been a fight to find something that works consistently to eliminate odor, even when I sweat hard, and to last a whole day. Chemistry Deodorant WORKS. It has further "lightened" my pits, no itching, no irritation. I don't even worry when I shave my armpits now :)

Every since I had my daughter antiperspirants quit working. I tried every natural one. Finally found Salt of the earth only one that works. It's in UK so expensive and hard to get. I decided to try Kosas , and they did not disappoint works for days. I'm totally switching.
