Why Did Laser Treatment Result in Demarcation Lines?

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?

A: Hyperpigmentation following laser

It sounds like you had what would be considered one of the safest lasers for asian or daker skin (Sciton Profile).

The Erbium Yag laser is less likely to cause any pigment changes than CO2 or other ablative laser devices. Sometimes pre-treating with a bleaching cream can help avoid this.

But at this point I recommend discussing this with your doctor and they may recommend Tri-Luma or another bleaching agent and this should resolve your problem in 2-4weeks.
