I have had acne since middle school and I am 16 now. It used to be just one or two pimples on the forehead every week, but starting from

one year ago I have been getting acne all over my face, especially my cheeks. It starts off as a small bump and grows into a large

pustule filled with pus. I went to a dermatologist and they gave me diferin and told me to use cetaphil face wash and moisterizer, but none of

those worked. It has gotten to the point where I do not want to go out and I feel really insecure and almost depressed. Any help would

be greatly appreciated~also how do i get rid of these black marks and scars.
