Oral supplements are processed by our liver (the body's natural filter) before their ingredients can enter our bloodstream. Oral supplements do not work as effectively because our liver does not recognize these high doses of foreign ingredients, so it filters the majority of them out. This puts a lot of stress on the liver and is one of the leading causes of liver failure. By absorbing through the skin, our body can slowly digest and activate these highly effective fat-burning ingredients in a much more natural and consistent way.
