How Can Lip Nevi With Peeling Be Treated?

hi, i used to bite my lips often when i was young and it has caused some white spots to appear on my lower lips. I ve quit that habit now and im using lip balm daily. But still those spots does nt go away. Also the skip is peeling often. It appears loose over my lip and when i run it goes away. I want to get rid of those spots. Is there any cure for this ?
