hello doc, i waxed my upper lip and i think i was a little bit too harsh and pulled a little of my skin. it was red and burning for a while, after which it formed a scab which was peeling off, so i peeled it all off, and it ended up in a brown scar like mark. It is not peeling off, and it i have this hedious brown pigmented patch on my upper lip. Is there any way to get rid of it or is it permanent?
