The drooping of the back and inner parts of the upper side of the arm is usually caused by fat deposits and skin sagging. This region of skin and subcutaneous tissue is more loose.

Medical aesthetics and aesthetic surgery bring many solutions to arm sags. However, surgery is the only solution to the severe sagging.
