Is this just an amazing coincidence, or are these two events heavily correlated?

So far it's been 1 month since I gave up all dairy products and I've experienced no breakouts in acne formation - whatsoever, on any part of my body. Cow milk, cheese, yogurt, cream cheese, mayo, er, cottage cheese, all of it. Although it was incredibly difficult at first, no other _significant_ dietary considerations have been made.
