I had my lip biopsy a year and a half ago. My lips still peel but not as much. My biggest problem is the scar from the biopsy. Theres a hard lump of scar tissue and the area is all red and purple and wrinkled and slightly numb. I hate my derm cause I only agreed to the biopsy cause she said it would heal in a couple weeks at the most and not leave a scar. When I went back a couple months later to complain about the scar she said either deal with it or go see a therapist. If anyone reads this dont ever get a lip biopsy.
