I've used AHA serum deodorants for years and I've never found a better one than Kosas. I always come back to it for the ease of application, the clean scent, and the value of the bottle. It's also aluminum free which is a deodorant requirement for me. $18 is a little steep but I truly feel that I get a lot out of each of these tubes - they last me many months. I apply at night once I'm dried off after showering, then will apply a different more scented deodorant in the morning (also aluminum free). I feel that the Kosas is an essential first step to start working overnight and kill bacteria before it even starts smelling, which then sets up my morning application of a different deodorant for success.
