Grey/bluish discoloration from piercing: what treatment? (photo)

I have this grey/bluish discoloration for where I used to have a nose piercing. I wonder if this is a blood vessel issue? And if so, would the same treatment work as for the telangiectasia? If so what would you recommend: IPL, sclerodermia or something else? I had 2 IPL sessions before but didn't see results. Should I have had more patience/treatments or should you see something by then? Thank you.
