Hi, since at age of15 to 16 I had bad habit of chewing and licking lower lip which lead to white and reddish patch (2*2cm) . Now it almost dry and flaky ( I stopped completely licking and chewing lip) . I have consulted about my lip condition with one of well known dermatologist . He suggested me tacroz and emolen ointment and I have once UV light therapy on lips but there no any improvement . Finally doctor advice me to under go skin grafting surgery . Is it possible complete recovery after surgery and any other alternatives treatment available  to it?
