I have blisters or rash 2 weeks post Fraxel 1550. Will they leave scars? (Photo)

I had my second treatment with the 1550 Fraxel laser two weeks ago. I had a tanned look and more significant flaking/peeling than first round. All looked great after a week, but then I got an itchy, rough feeling with redness. Patches of itchy rash are showing on my chin, nose, above my lips, and cheeks. They seem to be small fluid filled blisters and involve all of my face except my forehead. Some are larger than others. I have been taking Benadryl. I'm worried about scarring. Can you advise me?
