More discoloration after halo treatment? (Photo)

I had my second halo treatment 3 weeks ago and now my skin looks horrible. More discolored than before, kind of pixly throughout the face. It gets worse every day. What can I do? Doctor gave me Obagi products to use (Clear and 0.5 retinol) but I look even worse because my skin is all flaky. Should I do another Halo treatment to get rid of discoloration? On the picture I have makeup, without it's even worse!
