[b]There is no scientific co relation between eating the pizza and the acne. However eating lots of junk food may affect your body in the long run.[/b]
I think clearing your stomach once in a week or once in a month by observing a fast will definitely subside your acne. The root of main physical problem is stomach. I have prescribed the observing of fast only to many peoples in last 5 years and all has benefited from it. At least it has no side effects.
