here try (
Acne.org Message Boards -> Red marks left after acne) there are a few more regimes you can try. Don't give up, but you are far better teaching yourself to accept these that worry about them. Follow a good diet, keep up the excercise and time will see you get better. Also i do think as someone mentioned, laser treament might be needed for pick scars. There also a section that talks more about this under the acne forum.
hope this helps
