Is Acne caused by the Hormones in Milk and Dairy?

So, do the hormones in milk cause acne? I isolated pasteurized cow milk (and dairy) as the cause my acne.

• If I eat cheese made from raw milk, I get no acne
• If I eat cheese made from pasteurized milk, I get acne

I think the hormone levels in both raw and pasteurized products should be comparable. Of course it is possible that some producers of raw milk use different production methods, and the raw milk might contain less hormones – but then again I tried three different brands of raw milk cheese, and ate each time a large amount of raw milk cheese in one go, without getting acne. So, I don't think it's the hormones.

Another thing that makes me think it is not the hormones in milk, is that if I eat some dairy, I get about three distinct points of acne (pimples/papules/nodules) for about 100 to 150 grams of dairy from pasteurized milk. If it were hormones, I would expect slightly increased inflammation everywhere. But instead I see "the winner takes it all" with a mainly "all or nothing" inflammation.

Now this is pure speculation, but I suspect that "something" from milk (bovine IgA immunoglobulins?), that was changed during pasteurization, traverses intact from the gut to the blood. Then human immunoglobulins attach to this "something" and start forming immune complexes. Some of these immune complexes either dock to the relevant skin tissue, or they form there in the first place – and these would be the distinct points were then inflammation arises, because now leukocytes rush in and start a giant gang-bang at the expense of my no longer acne-free skin.

Still much to learn…
