Will this dark-grey skin around my mouth and forehead ever disappear? I had Fraxel more than 2 months ago. (Photo)

I am Hispanic, 45, dark skin, and had Fraxel. I wanted to treat Melasma spots on my cheeks but was left with a dark-grey skin shadow around my mouth and forehead. Used Hydroquinone 3 weeks prior to procedure. Skin around those Melasma spots was an even tone. 10 days after Fraxel -follow-up- asked about the dark-grey skin, said it was going to disappear in 2-3 weeks with hydroquinone 3 times a week. Pre and Post-treatment I have been very diligent about Sunblock. Nothing helps, is getting worse!
