Keep in mind that simply doing the Liver Flush is not the entire answer. Acne is a classic sign of colon congestion and poor nutrition. The biggest food culprits are - dairy, gluten (especially wheat), refined sugar, caffeine, red meat - all these things slow down the colon and encourage bad bacteria growth, which affects the whole body.
My Acne has improved recently by using WOW by Nutrafina. It is a colon cleanser that works herbally to loosen and work away the oldest gunk on the colon. It also has liver herbs that detoxify the liver and thus the blood. It is a really good "cleaner outer" overall, and completely safe, even for kids.
