no

1540 gave me wierd dry lines on what was complelely smooth skin and big red squares and track marks. I still have redness 4 months later. c02 gave much more noticable results and amazing results combined with PRP. still slightly pink from c02 but no wierd marks. You could try fully ablative erbium yag. It ablates all the skin but isnt as deep as fractional c02

You could get c02 spot treatment, ie just on the scars and not the whole face.

I would ask for before and afters and make sure he's VERY knowledgeable
