The only thing that worked for me was the liver flush. (and diet of course) Its his livers job to keep his blood clean apart from its many other jobs.. If his liver is clogged, it cant do its job; and even the healthiest most natural foods won't do him much good, if he can't digest it properly!!! Me and many others here were willing to do anything to get rid of the acne.. the question is, is he? but maybe hes just skeptical of the flush, and thats normal amongst lots people also. :)
