That's because the cause of acne is so different person to person. There's teenage acne which definitely isn't caused by diet and goes away eventually. A regimen of clearasil works for these lucky folks. Then there's the severe type that always recur every month. Less than 1% of the population has this and the standard advice never works for these people. For some, changing diet works. For some it doesn't but thats the type of acne that's possibly linked to diet. So saying there's no link is really misleading. There's no universal law that says red meat causes acne for everyone but that doesn't mean it doesn't cause acne for you
