Upper Arm Lift, or Brachioplasty, is a surgical procedure that removes loose skin and excess fat deposits in the upper arm. With age, upper arm skin can become loose and flabby. Plastic surgeons will discuss brachioplasty with patients who want to tighten this skin and look as good as they feel. In some cases your plastic surgeon may suggest that liposuction be used alone or in conjunction with an arm lift to remove excess fat in the upper arms.
