Interesting advice, although I disagree with cutting out soy from the diet. It doesn't explain how the majority of people in Japan (parts of Asia as well, although not as much as the Japanese) have acne-free skin since they have soy products like tofu and miso soup pretty much every day of the week. I have acne for 8 years (and counting), and recently my breakouts have decreased a little, which I believe is from my upped intake of tofu and other soy products. On the other hand, I fully agree with the cod liver/ omega 3 fish oil. The only thing is that you have to take large doses or it won't make much of a difference (acne.org has some pretty good reviews, and it seems to work the best for people who take 3-4 times the regular daily intake).  However, like with all supplements, it did not eliminate all of my acne. With that said, I am very interested in the butter. :)
