As we age skin, our skin loses its elasticity and succumbs to the effects of gravity. This may result in a saggy segment of skin on the back of arms. This is usually most obvious when the arms are held outstretched.
An arm lift or brachioplasty is an operation that aims to excise the redundant segment of saggy skin on the back of the arms through an anterior incision along the inner aspect of the arm. This will leave you with a scar on the inner aspect of the arm. This is generally unnoticeable because of the location where it is placed and generally does not interfere with shoulder movement. It results in a tighter, younger appearance of the arm.
