Hi,my face and neck is covered with black marks looking like black lots or some sort of fungus I tried Trinbrite F for 1yr now,sometimes it look lighter,I also use sunblock,and sometimes I look darker,a few days back it spread to places that was clear and my face look horrible I don t know what to do,previously I visited skin doctors but they only gave me some cream to rub on it together with sunblock,thank you
