Ya the protein and calcium is my problem as well, i'm guessing eggshell could cover calcium and if you took enough you wouldnt have to worry about the phosphorus in meat which could cover protein? Just an ideaI don't know about that one. I know that my own acne has to be related to the way aspirin interacts with hormones, because it always improves after taking it.
Do you have a source on skim milk causing more acne than higher fat milk?
I've completely avoided dairy at stretches of time to see if my acne improved, and it didn't. Admittedly I've never avoided dairy since Peating, so perhaps it would have an effect on me now. What I'd worry about if I removed dairy is whether or not I'd get enough calcium, and what to replace the protein with.
