Hi and thank you for your question regarding if it's possible to get a second arm lift. The answer is yes, it IS possible. I performed many arm lift revisions over the past 23 years and most times I'm correcting for surgeon error. However, if you lost more weight and the skin didn't shrink wrap back, you may be a great candidate for a second arm lift. It will be important for your plastic surgeon to excise the previous scar and dissect the plane to get rid of as much skin and fat as possible. I specialize in arm lifts. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, please contact my office. Since a brachioplasty or arm lift surgery is a difficult procedure, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
