Is it possible to fix a dent left from a improperly healed wound?

I woke up one day with a bump on my nose. I thought it was a pimple, but it itched, so I'm assuming I got bit by something. I accidentally scratched it open and it scabbed over. The scab fell off prematurely and there was a gash left under it. I thought it would heal, but it's been 2 1/2 months and the dent is still there. I wasn't sure if it was still healing or if it had healed already and left a dent, so I recently bought some Medihoney to see if it would help. I think it already healed.
