Mole already removed/biopsied - deep pigmentation left. Best way to remove? IPL, BBL, or something else? (photo)

About 6 months or so ago I had a mole removed from my nose and biopsied. It was non cancerous thankfully, however I am left with what I believe the derm called a "deep pigmentation". The area is completely flat but it is very dark almost like the mole is still there, but it looks like a dark freckle or birth mark. I would really like to get this removed because it bothers me greatly however not sure what the best way to do so is.
