I can vouch for the replies that talk about healing your gut. Since Ive started eating Primal, eliminated fruit, starches, dairy (except raw butter), etc my acne has improved considerably. I used to have bad acne around my nose.
Lately Ive been cooking up lots of bone broths and digesting them (aka GAPS diet) which I feel is helping A LOT!
Applying coconut oil topically broke me out badly when I first tried it about a year ago.. I started to apply it again 3 months ago and it has worked wonders. But obviously, true healing of acne comes from within I know believe.
