can cutting dairy from your diet improve acne?

I heard that milk can cause acne because the hormones that are in it. Should I assume the same for cheeses? If the hormones come from the cows, should I avoid all dairy products (milk, yogurt, cheese) and beef/steak too?
I tried to cut dairy out of my diet to see if my skin would improve at all, but I've realized it's very difficult to avoid cheese in a college cafeteria.
