3 weeks post Fraxel laser restore with redness and Fraxel mark on my cheeks. Is this permanent?

I am 3 weeks post fraxel restore laser and my skin still looks red with fraxel mark. With my first treatment I healed in 10 days but with my second treatment I am not healed yet(they used higher frequency this time 60 Mj). I went to see my dr last week and she gave me phloretin c serum to speed up healing but no improvement yet. Is this mean I got permanent redness or hyper pigmentation? What treatment would help me out? I am loosing so much sleep over this as I am scared my skin is ruined forever:(
