Red patch after peel post CO2 laser (Photo)

I had a fractional CO2 laser 4 days ago and know the proceed as I have many sessions before for acne scars. This time I had full face for both scars ( very swallow now) and firmness/ lines. This times it is not like before I stated to peel at day 2 (one spot) and in this early areas of peeling the skin are very red, shiny and raw. I did not peel off myself it was naturally. Is it normal to peel so early? some areas are raw & red and other more pink... a bit anxious about the ones very raw!
