Why it's done

As you get older, the skin on your upper arms changes — sagging and becoming loose. Significant weight loss also can cause the undersides of your upper arms to droop.

While exercise can strengthen and improve muscle tone in the upper arm, it can't address excess skin that has lost elasticity.

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.
