Miradry is a system specifically designed to treat axillary hyperhidrosis. It does this by pulling the skin of the axilla away from the underlying anatomic structures and then heating the apocrine sweat glands, which lie at the junction of the deepest layer of the skin and the subcutaneous fat, with enough microwave energy to shut down the function of these glands. It is theoretically possible to use the same technique to treat hyperhidrosis of the hands and feet, etc., but the anatomy of these areas is different from that of the axilla, and so the design of the system would have to be modified accordingly. But I would not be surprised to see this done in the not too distant future.
