More about this product

Why we chose it

Kosas takes a skincare-first approach: the active ingredient is mandelic acid (an AHA), which lowers underarm pH to inhibit odor-causing bacteria without baking soda or aluminum. The fragrance-free variant has no scenting agents at all. The full ingredient list is published on the brand site and reads like a serum, not a traditional deodorant.
