Our office specializes in lip scar revision. White scars and lumps on the lips can be corrected surgically with a minor lip revision procedure.

Pictures would be helpful to give you the best advice, but from the description of the scar on your lower lip, I would say that it is possible that a surgical scar revision could improve your scar. This procedure could be done in the office with just local anesthesia. The cost is going to vary by surgeon. I would recommend consulting with a facial plastic surgeon or plastic surgeon.
