Will these lines of demarcation go away...they are so dark? Please tell me this isn't permanent damage (Photo)

2 months ago I did the C02 laser on face and neck.it was aggressive as I'm 28 and probably didn't need it. My skin now looks dark grey or brown where the laser was used. I have 2 lines of demarcation on my neck that are darker them Natural skin. Also a couple white lines on my face where the laser wasn't applied. It looks like I have a dark mask on and it's really blotchy. Also if i look really close it looks like i can see the little holes from the laser.I have done 1 glycolic chemical peel
