When PPC is injected into fat cells, it has a detergent like effect and causes fat cells to rupture and then dissolve. The liver then breaks down this fat and it is excreted by the body. These fat dissolving injections also cause tightening of the skin in the treatment areas. This is an advantage of the technique over liposuction in certain areas. Areas which can be treated by injection lipolysis are: abdomen, back fat rolls, love handles, thighs, knees, neck arms and face.
