There are several sites and such out right now there saying everything about acne. They generally say things like "it's due to clogged pores, excess sebum, and so forth... " but what they will not say is what the clogged pores is due to. This is just like saying a heart attack is caused simply by clogged arteries. Then they promote you some stuff to unclog the particular arteries. Your arteries are still planning to get clogged again. The main lasting solution is to change yourself and start eating unclogging food items.
