Why Did Laser Treatment Result in Demarcation Lines?

hong
I am a 42-year-old Asian woman. I had full facial Micro Laser Peel (20 micron depth) and 20% ProFractional Laser Resurfacing (200 micron depth) 16 days ago. The day of the procedure, I had a lot of bleeding all over my face and could see very distinct parallel longitudinal red bands (3 on each side) running down my cheeks, as if some of my skin had received far more exposure to the profractional laser than other parts.Beginning a week after treatment I started to get a hyperpigmentation reaction exactly corresponding to the vertical bands on my cheeks. There were no bands on my forehead or chin following the procedure, and I have not had any hyperpigmentation occur on those areas either. Can anyone explain what is going on?
