Fluctuations in weight, growing older, being over-weight, and even heredity can cause your upper arms to be overly large and/or have a drooping, sagging appearance. Exercise may strengthen and improve the underlying muscle tone of the upper arm, but cannot address the excess skin that has lost elasticity or underlying weakened tissues and localized fat deposits.
If the problem is only size, a liposuction is the recommended treatment, but if there is also significant sagging, the arm lift (brachioplasty) is required, sometime in conjunction with the liposuction.
An arm lift reduces both excess skin and fat between the underarm area and elbow. It can reshape your arm resulting in a smaller arm with smoother skin and better contour, and it can result in a more toned and proportionate appearance.
This procedure requires a light general anesthesia and the arm is wrapped in a dressing for a few days.
