I had always felt like I had sweat more and had under arm odor more than anyone else I knew. I was 38 before I heard about miradry but I wish it would have been available to me 20 years ago! I had read some reviews that said you might need more than one treatment, but mine only took one! With the results miradry gave me, I would have gladly paid for a second treatment!! I still wear deodorant...
