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.

Wow, this really does eliminate arm pit odor! I have such a difficult time trying to find something that effectively masks my arm pit stink, but this product does not mask, it eliminates! It took about 3 days before I could detect zero odor. The scent of the product is not overpowering either. I love it!! I will be a customer for life with this one. So happy!

I’ve tried a few “clean” or “healthy” non-aluminum deodorants and none have worked. But I’m a scientist, I know traditional deodorant isn’t great, and going au natural every day isn’t an option for me. I did not expect this to work. But it does, consistently, even through working out during a heat wave. I like it so much more than what I was using before. Bonus: it doesn’t leave marks on your clothes.
