miraDry® for Feet and Hands

Due to the efficacy of miraDry® for treating excessive underarm sweating, patients frequently inquire about whether miraDry® can be used to treat hyperhidrosis of the hands and feet. Currently the answer to this question is no, it cannot. Below are more details on why miraDry® cannot treat the hands and feet areas.

FDA Approval & Device Design

miraDry® is currently only FDA approved to treat hyperhidrosis of the underarms1, and the current miraDry® hand-piece is specifically designed to fit against and apply light suction to the skin in the underarm area. The skin skin texture of the hands and feet areas differ from the underarm area, and the current design shape does not allow for adequate suction, preventing an effective treatment of the hands and feet.

Microwave Energy’s Potential to Damage Vital Structures

Unlike the underarms, the hands and feet have vital structures that are too close to the skin, which leaves them especially vulnerable to injury, including:

  • arteries
  • nerve endings
  • tendons
  • blood vessels

These structures are closer to the surface of the skin on the palms of the hands and soles of the feet than they are in the underarm area, and could be damaged if the current miraDry® device were used for treatment.

Treatment Options for Hands & Feet

For now, other treatment options available for excessive sweating in the hands and feet include topical medications, oral medications, surgery, and Botox® injections.
