Laser genesis burn help. How do I care for this? (photos)

I had genesis tx done by a NP at my derm office on 2 spider nevi. The same night of it I had brown crusty spots appear. I want back to derm office and was seen by another NP. The np reassured me it looks good it’s fine. Yesterday the brown spots peeled. I’m left with red pink skin where they were. I’m afraid I have permanent scaring. My area of concern is now worst. How do I care for this new red skin? What happened? Still have nevi also. Didn’t work!
