You still need to keep the colon clean, as that cleans the lymphs, but switch to a fiber/herb cleanser as that will cleanse both the colon and small intestine (don't know why we call it the small intestine, it's 22 feet long!!! but then it IS thinner). Your small intestine could still have mucoid placque in it.
See the Acne notes for a list of things to do/not do to cure acne. Good liver management is KEY, but again, to properly cleanse the liver, you have to keep your bowels moving too as the liver dumps things into the small intestine.
