Animal rights group PETA has put up a billboard near two high schools in Missouri hoping teens care more about their looks than they do about dairy. The billboard shows an acne-covered teen with a milk mustache and says “Got Zits? Studies show: milk and cheese trigger acne. Ditch dairy.” Is PETA right? Does dairy cause acne? Also, what do the parents in the school district think? We have the answers! Mostly.
