I had terrible acne on my chin and it took a good year of eating primal for it to clear up and dairy was not the cause. Fruit makes me break out so I suspect sugar is the cause for me. Probably different for everyone, though. You may just have to give primal eating time to do it's job and experiment a bit with eliminating problem groups such as nightshades, dairy, simple sugars. Do one at a time for 30 days and then re- introduce and see how it affects you.
