The topic of dietary intake and its influence on acne will continue to be controversial and it is clear that further research is needed in order to fully elucidate its precise role. However, we can no longer discredit the association as a mere myth. Although we cannot treat acne solely with nutrition, we can certainly shape its outcome. Even if no single food directly causes acne or effectively decreases its symptoms, we can still stress to patients that diet can lessen or increase its severity.
