Had a lip lift 3 yrs ago. Slight lift improvement and some scaring. In May 2016, had second lift which removed scars and more lift, but now left with noticeable puckering line scar when I smile. If second doctor had cut higher toward nasal openings, I don't think such a scar would be noticeable. Is it possible for a third lift to remove puckering scar with incisions higher up?
