An arm lift, also known as brachioplasty, can remove the excess skin and fat deposits, leaving the upper arms with a more pleasing and youthful contour. As a person ages, upper arm skin can become loose and flabby. Your plastic surgeon will consult with you about undergoing surgery for an arm lift if you wish to tighten this skin to look and feel more youthful. The incision extends from the elbow to the underarm, and sometimes on to the side of the chest. In some instances, your plastic surgeon may recommend that liposuction be used alone or in conjunction with an arm lift to remove excess fat in the upper arms.
