Typically, the saying is that chocolate and greasy foods make you break out. That's the myth. OIL contributes to acne. But, that's the oil your skin makes, not what you ingest. If you're allergic to a certain food, you may break out in hives. But, that's not acne per se. As far as foods making you produce more oil, not directly. If a particular food causes you stress, then yes because stress produces oil.

BTW SERB...Overly dry skin can cause acne as well! I know confusing right!?! Naw, you just have to strike a balance with your skin. Nothing extreme...
