I agree with the suggestion to check out information on this site regarding colon and liver cleansing. There is a wealth of information here. If you do your homework and follow the directions, these cleanses can really help your body heal itself of the conditions causing acne.
In the meantime, here is a topical product that's worked for me: www.no-acne.com. It's an inexpensive facial or body wash that really helps clear even cystic acne. I've seen very good gradual results over the past three months. It's inexpesive and offers a lifetime money back guarantee. Keep on truckin. We've all been there but there is hope!
