Pseudoscience and false hopes. None of this shit cures my acne that lives a life of its own despite what I fucking eat. I have taken evening primrose and borage oil up to 18 grams a day and it did nothing. I have tried so fucking many natural remedies over the years that it makes me angry to see these people joining 2012 and immediately sharing some kind of cures and bullshit.
And those "cure acne naturally" "secret acne cure that drug companies don't want you to know" ebooks and sites are the biggest load of shit there is.
You gotta find that thing that works for you, and/or the reason for your acne. I've been using Retin-A since I was in my teens and it has worked well for me, though I still get pimples but seemingly only when I am eating a diet that has a lot of sugars and carbs in it. In the past few months I've cut out a lot of sugar and carbs and my skin has been consistently clearer--in fact, clearer than it has been in my whole life thus far.
You gotta take a deep breath and approach this thing scientifically.
