Milk does aggrivate acne, but you are all thinking it does for the wrong reasons.
The actual reason is most likely because cows are made to produce enough milk to meet our needs using IGF growth hormone, this along with hormones in a pregnant cow exist in the milk they produce and in the milk we consume. The hormones worsen acne by causing increased sebum production, or buy increasing skin proliferation, in other words increasing the chance pores will get blocked. I further hypothesis that organic milk, that has not been produced with the aid of growth hormones would be as good as drinking no milk.
A lactose allegy could also be to blame because in this case the small intestine is lined and nutrient absorption is componsated, but hormones are far more likely to be resonsible in most cases.
I cut out milk with great results.
-be sure to eat more fruit and vegetables, this stops you excreting so much calcium, you don't want to trade acne for osteoperosis later on in life.
