Thank you for your question. According to the FDA, miraDry is approved in the United States for use of axillary hyperhidrosis (underarm excessive sweating). Unfortunately miraDry has not been approved by the FDA for use in other areas of the body. Use of electromagnetic energy technology has been used safely in other areas of medicine for years. Established medical uses of electromagnetic energy include applications for cardiology, cosmetics, general surgery, urology, and oncology. Miramar Labs is the first company to gain FDA clearance to use electromagnetic energy to combat excessive sweating of the underarm (by eliminating or damaging sweat glands) using miraDry.While miraDry is great news for those who suffer with underarm sweating, odor, or hair removal, the device is not yet "approved" or optimized for use to treat excessive sweating of other areas such as buttocks/crack area, hands, feet or face. Feasibility studies of a smaller device for use on non-underarm areas are currently underway and we will be sure to let you know by our website of any further approved uses or approved devices that come about in the future.Best Regards, Sincerely,James Fernau, MD, FACSBoard Certified ENTBoard Certified Plastic SurgeryMember of ASPS, ASAPS, ISAPS, The Rhinoplasty Society, AAFPRS, OTO/HNS, ASLMS, International Federation for Adipose Therapeutics & Science
