I've been looking for a natural deodorant option that works for my body for years. The only kind I've found that do, and that my body doesn't quickly adapt to and leave me stinking again, contain baking soda. BUT the baking soda would leave a rash in my armpits. NOT THIS ONE!!! Whatever formula they use is strong enough to keep working LONG TERM and gentle enough to keep my pits happy and rash free. Thank you so much! I'm almost done with the 1st one I purchased which has lasted a few months. No more natural DO cycling, trying to keep the body odor at bay, and eventually going back to chemical filled options. I hope and pray you keep this company and deodorant going till our Good Lord returns, because I'll be a customer till that day!!!
