Lipodissolve is perfectly safe. Phosphatidylcholine (PPC) is a component of every cell in our body. As well, PPC is produced naturally by our bodies. It is highly concentrated in liver cells and fat cells and is a large part of nerve cells. PPC injected to dissolve stubborn fat deposits is derived from the soy plant. It has been used in other fields of medicine to treat fat embolism in the lung and for lowering blood cholesterol levels. 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.
