An arm lift — also known as brachioplasty — is a cosmetic surgical procedure to improve the appearance of the under portion of your upper arms.
During an arm lift, excess skin and fat is removed from the underarms — between the armpit and elbow. The skin is then draped back over the newly repositioned contours to create a more toned look.
You might choose to have an arm lift if the undersides of your upper arms are sagging. An arm lift might also boost your body image.
