Long Healing and Redness After Micropeel and Profractional?

Hello, I had a micropeel (50microns) + Profractional (450 microns) 6 weeks ago. I had a profractional before at 400 microns and had healed fast (1 week). However this time I turned out very red. After 4 weeks my dermatologist prescribed me topicort for the redness and finacea to prevent hyperpigmentation and said that I am taking longer to heal. Can this be true? just taking longer to heal? Thanks
