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.
