He went too high with the intensity on the upper part of my face

I'm glad others had good experiences with Dr Blair, mine wasn't great, I had c02 laser. He went too high with the intensity on the upper part of my face. It healed several shades darker than the lower portion of my face. He suggested hydroquinone to lighten to darker skin. It may be effective, but it's banned in many countries for risk of cancer. I'm having to use heavy foundation to cover the difference in shades of my skin until I can save enough to go see a dermatologist to correct Dr Blair's mishap that I paid for.
