My sister tried the elimination thing for her skin problems and nothing really made a diffrence. No chocolate, she had break outs. No milk, she had break outs.No meat, got break outs. Still with creams and washes she had to deal with it. Eventually she grew out of it. Hormones will do a number on one's skin. My own child had to deal with break outs for a while and they stoped. The acne was gone almost as fast as it appeared. I gave her a facial scrub she did once a week and for bad pimples good ole Clerasil. And we left it alone, no squeezing or fussing with it. Good luck with your son's skin.
