I have acne.
Lesions tend to crop up on the face, neck and upper body-some of our most visible skin zones.
But the one most teens get is called acne vulgaris. There is no scientific evidence to prove that acne is caused by French fries, pizzas or chocolates. If your parents had acne as teenagers or young adults, you're more likely to have it, too. Acne is hereditary. It runs in families.
