Are there any procedures to help minimize my scar on my vermilion border from a mole removal procedure? (Photos)

About 15 months ago I had a flesh colored mole removed from the vermilion border of my upper lip. I should have probably left it alone because I have yet to regain my lip color back, as well as a little bit of regular skin just above it. They used the Ellman Surgitron for the procedure. I am at a loss because there has been no improvement to the color of the scar. Is there anything I can do to help improve the looks/color of my lip?
