Strange presciption: Using Retinol on 5th day after my first treatment then chemical peel. Any suggestions?

After my 1st laser treatment, doctor prescibes me to use Retinol from 5ft day (Skinceutical Retinol 1.0) On my 7th day, my skin was healing nicely,just a bit pink, almost back to normal, he put me on a chemial peel TCA 50. After skin peeling off, the light pink marks now 5 times daker, brown-red color. From advices here, I see my case is going against lot of your advices. I called him but he said looking red means skin is responding well and producing new cell. I'm totally at lost here.
