Fluctuations in weight, growing older, and heredity can cause your upper arms to have a drooping, sagging appearance. This is a condition that cannot be corrected through exercise.
An arm lift, or brachioplasty, is a surgical procedure that can help. Arm lift surgery reduces excess sagging skin that droops downward while tightens and smoothens the underlying supportive tissue that defines the shape of the upper arm.
Arm lift surgery may be right for you if the underside of your upper arms are sagging or appear loose and full due to excess skin and fat.
