So I got 2 or three zaps per side treating a few broken blood vessels and 2 small frekles. I was left with a huge spot redish brown. I got my treatment about four weeks ago noticed this about a week ago. These were not there prior. I have been staying indoors because I don't want to make it worse. What should I do? What is this? Please help. Dermatologist said she didn't know if it was pih or melasma forming. She said she thought pih
