A local anesthetic is administered to the underarm with minimally invasive injections for comfort. Then a handpiece is used to precisely direct energy to heat then cool the glands. The results are long-lasting as sweat glands do not regenerate. The miraDry procedure typically lasts about an hour, resulting in 82% reduction in sweating in as little as 1 treatment. Some people, however, will need two treatments.
Following treatment, there will be some swelling, tenderness, and possible numbness for a few days up to a few weeks. Applying ice packs for the first 24 hours will help these side effects. There are no restrictions and daily activities can be resumed as tolerated. Results are immediate but it may take 3 months to see full results.
