I had spider veins on the nose, and got laser. Unfortunately, I got scars because of that. What do I do? (Photo)

When I got the laser I noticed it hurt more this time, than the other times, and I told the nurse that. But she said it was normal. Afterwards the dermatologist of the clinic gave me a creme, and told me the scars will disappear in 3 month, but Im a little bit scared it won't? What do you think? Can I demand they will pay for CO2 in case the scars doesn't disappear? I already got my money back, and another dermabrasion treatment for free. But I would rather have a CO2, so I can remove the scars
