Hi. I am 20 years old. I had pimples all over my face and I got a full treatment of 4 months to get ride of them. Now as the pimples are gone I am left with the black spots and pimples marks over my face. I have white heads all over the face and they make my skin very rough. Can you tell me how to get ride of white heads and the pimples marks and get a fair smooth skin.
