Losing a significant amount of weight can be a wonderful, life-changing event, but can also lead to loose and saggy skin between the elbow and armpit. If you want to tighten up the skin under your arms, an arm lift, or brachioplasty, can help by removing the loose and saggy skin. Liposuction can be a component of brachioplasty.
During an arm lift, excess skin and fat are removed from the underarms — between the armpit and elbow. The skin is then draped back over the newly repositioned contours.
