I don't have severe Acne problems but I have had a lot of black heads and white heads all over my face and even on my chest. I've done 9 Liver Flushes so far and that has improved my skin condition a lot. From constant squeezing in front of the mirror every night to now maybe a couple a week.
But since starting to oil pull about two weeks ago it seems my skin is clearing up even more.
Maybe you already tried this but if not, please visit the oil pulling forum here on Curezone where you can learn about the procedure. It's so easy and also very easy to incorporate in your daily routine. For an added plus the oil pulling people are a very supportive and cheerful bunch which is always a good sign that they might be doing something right : )
And as others here have suggested, try Liver Flushing as well.
