Good for you in your decision to maintain cleansing and stay away from Acutane! I too believe that it would only further worsen the problem.
Someone once told me that that Acne cysts (the giant dime sized, under the skin zits, which i am unfortunetly afflicted with) are caused by tapeworms. Though i'm not sure if this is true, i do believe that there is some connection. The weeks of my parasite cleanse were the worst breakouts that i have ever experianced in my life. Hudge, monsterous, swollen cysts covered my face. Strangers approached me in public and asked me what was wrong with my face,(i cried-people can be so rude) it was awful.
It's gotten better, but my acnes still there.
