Your concern is understandable at this point, but it is far too early to be worried. Whenever skin is removed, like in a lift procedure, there will be bunching up of the remaining skin somewhere, usually at the end of and incision line. We call this a 'dog ear'. In your case, it appears at the outside end of your under breast incision. It can take 6 months or more for swelling and skin changes to normalize. It is possible for the dog ears to go away completely. This is why we advise waiting at least six months before doing a revision. There are some situations that will not improve with time, but many will. Give it time is the best advice for now. Good luck.
