Totally anecdotal, but too much chocolate is what makes me erupt. And I prefer dark chocolate, so it might be the chocolate rather than the dairy.

Eating a large bar of dark chocolate should differentiate, purely in the interests of science of course.

Chocolate is the culprit for me as well. Sometimes sugar too, but, not as frequently or as much as chocolate (but the acne seems subtly different from the chocolate one).

Out of curiosity, does chocolate have any other effects on you besides the acne? Like easier bleeding/blood thinning? Or other inflammation besides acne? It has more than one effect on me and I surely can't be the only one observing it.

I haven't noticed any anticoagulant effect.

I consume chocolate in the evening and do sometimes clear walking tracks before breakfast, which often involves scratches. So I would expect to have noticed wounds bleeding for longer than usual.

Try comparing British to American process chocolate. Makes a huge difference for my wife. American chocolate triggers a bad outbreak. Different chemical process, different quality of ingredients.

Its the dairy

[RobertRoberts]

I would add possibly polluted or adulterated dairy. Raw milk (anecdote) may not cause the same issues as processed dairy.

Also, I would add that most processed dairy (besides just plain old milk) is mixed with many other detrimental ingredients. So there may be a cause/effect relationship overlap with other foods.

I can't speak for other people's cases but in my case it's definitely not the dairy. The only time dairy ever had an effect on me was pre-elementary school when eating too many egg started giving me pimples, so I cut down on that and that fixed it. Never had a problem with it again.
