I had microdermabrasion done 4 months ago, and a patch developed shortly after. When I went this month, a specialist told me it's a fungal infection and recommended I use Sebifin, as well as Melaglow. But I don't have any irritation in that region. The area is dark red at times and light red at other times. Do I really have a fungal infection? How can this happen right after microdermabrasion? Please suggest a remedy.
