She very clearly stated that Last Ages exchanged the time of the user for turning back time. It really shouldn't come back slowly.

And while I like the "age vampire" theory, I doubt that Ultear as she was after becoming old would want to do that. She seemed quite happy about the way things worked out and not at all inclined to chase after her lost youth.
