No peeling skin after CO2 laser. Is this normal?

I just had my CO2 laser fractional done 7days ago for my acne scars and ice pick scars. After 5days all my scabs has dropped and my acne scars getting lighten. My skin tone getting even as well. During the healing process my skin did not peel at all but feel itchy. I wonder whether is this normal? Because most of people who did this laser will have skin peeling.
