Arm lift, or brachioplasty, is a surgical procedure that reduces excess sagging skin that droops downward, tightens and smoothes the underlying supportive tissue that defines the shape of the upper arm and reduces localized pockets of fat in the upper arm region.
Fluctuations in weight, growing older and heredity can cause the upper arms to have a drooping, sagging appearance.

This is a condition that cannot be corrected through exercise.

The procedure:

Arm lift can be done under intravenous sedation or general anesthesia. Incision length and pattern during arm lift surgery depend on the amount and location of excess skin to be removed, as well as the best judgment of plastic surgeon.
Incisions are generally placed on the inside of the arm or on the back of the arm, depending on the surgeon's preference, and may extend from the underarm (axilla) to just above the elbow. Excess fat may be directly excised or treated with liposuction.
Depending on patient specific condition, incisions may be more limited. Then, underlying supportive tissue is tightened and reshaped with internal sutures. Finally, the skin is smoothed over the new contour of the arm.
The smoother, tighter contours that result from brachioplasty are apparent almost immediately following the procedure, although there will likely be swelling and bruising.

Recovery

During recovery from arm lift surgery, dressings or bandages may be applied to the incisions, and the arms may be wrapped in an elastic bandage or a compression garment to minimize swelling following surgery. A small, thin tube may be temporarily placed under the skin to drain any excess blood or fluid. Resume normal activity and exercise is possible after seven days.
