Brachioplasty is a surgical procedure that removes and tightens excess skin and fat from the upper arm, creating a smoother contour and toned shape. The surgery can also help reshape underlying tissues to give your arms a more toned look. It is important to note that this surgery is not intended for weight loss, as it cannot remove large amounts of fat or treat obesity issues. However, if you are looking to reduce sagging skin due to weight loss or aging, brachioplasty may be right for you.
