The oxygen helps you to detox, so you need to do Liver Cleanses still a few times a year. A person should do this anyway, and oxygen therapies does not eliminate that need. :) Right now H202 spray directly on skin over my liver is what is making me feel better! I detoxed too quickly with some other products and my liver is saying "clean me!". Right now I'm doing the colon cleanse, to be followed by the liver cleanse...
