Blotchy Skin After Palomar Laser?

I had a Palomar 1540 treatment done 7 days ago. My face is blotchy with red marks but the swelling is gone. Does this ugly look stay forever?

My dermatologist has given me Desonide cream to use for 5 days, but every morning I still wake up and it's still there. The marks look horrible and impossible to hide. What's up? Did I totally screw up by getting this treatment? I'm in my mid 50's, white, and was going after a few wrinkles, now I resemble a waffle face. Oh the price we pay to hang on to youth!!lol
