A.Emsculpt has been FDA approved for the treatment of the abdomen and the buttocks. There are practices that will treat other areas such as the arms. I agree with Dr.Avalianithat it depends on the expertise of the practitioner to decide the safety and efficacy of treating “off-label” areas with Emsculpt. There is not a contraindication to treating the arms of patients who have had mastectomy. Good luck and be well, God Bless.
