Results from arm lift surgery are visible almost immediately, though it may take several months for maximal improvement. Visible scars will remain, but will be concealed as much as possible under the arm. Overall results are long lasting provided you keep a steady weight and exercise regularly. As your body ages it is natural to lose some firmness, however, most of your improvements should be relatively permanent.
You will return to your plastic surgeon's office for follow-up care at designated intervals to evaluate your progress.
