Kybella Produces amazing results! The active ingredient in Kybella is synthetic deoxycholic acid, a naturally occurring molecule in the body that breaks down and absorbs fat by breaking down cell membranes of fat cells.  When injecting Kybella, the response is that fat cells are targeted to destruction.The dissolved fat then gets cleared by the lymphatic and circulatory systems, as any waste product in our bodies does. These target fat cells remove themselves gradually over the span of several weeks. As for the Kybella/deoxycholic acid, it follows the same path; It gets metabolized and broken down, and then excreted as waste.
