Brachioplasty or arm lift is a very popular procedure for slimming the upper arm. Sometimes it can be accomplished with liposuction alone and a short incision high up in the armpit. Other, more severe cases, require a longer incision with removal of excess skin and fat. It is commonly done after profound weight loss. A newer technology called Inmode Bodytite can tighten skin through a very tiny incision using radio frequency energy.
