Arm lift scars, as a medical professional would say, can take anywhere from one year or longer to completely heal and fade. But the ultimate look of scars may differ from person to another and is based on a patient’s skin type, as well as how closely they adhere to postoperative care guidelines. If you have any questions regarding the appearance or healing of your arm lift scars, it is advisable to speak with your surgeon. If necessary, you can go to a plastic surgeon who specializes in scar revision for additional assessment and management.
