I have black spots on my legs since I was 11, now I am 33. The process of the formation of the spot is - First I would develop a pimple, little translucent, after some days I could see something light black in that translucent pimple, after that it would become a spot. After so many years this process has not stopped. I still have active pimples and cant tell you how much itching I face!! Have some lighter spots on arms, back and abdomen too. Please help. Regards
