Can miraDry be done on the hands and feet?

mrhyper,
You are correct that a new miradry hand piece is on the way with the ability to treat the hands. Realistically, the process of bringing new technology to the market takes time. The recent acquisition of miramar, the makers of miraDry,  by Sientra last month may also influence the release date.

According to the company that makes MiraDry, they just completed a clinical trial for MiraDry treatment of hand sweating.  They expect MiraDry for hand sweating to be available some time in 2018.  While you are waiting for it to come out, you can do Botox or Dysport treatment for your hand sweating.
