Is resurFX a good option for a nose scar? (Photo)

I sought advice on treatment for an old scar on the side of my nose which was caused by a stitch and is now indented. The dermatologist recommended 3 sessions of resurFX which is a fractional non-ablative laser. She said CO2 would be too harsh as my nose skin is very thin, and did not recommend anything else yet. I’m wondering if this will be effective enough? I don’t want to be lead into spending money for multiple sessions of something that makes minor difference.
