What nonsurgical techniques are available to eliminate excess fat?
There are no nonsurgical methods of fat removal that have been proven to be effective. However, several types have been widely advertised despite this. One, called Ultrashape, uses external ultrasound energy applied to the skin to presumably dissolve the fat below. Another, called Coolsculpting, applies external cooling to the skin with the same goal in mind.
Mesotherapy, also called lipodissolve, is an invasive but nonsurgical method where substances are injected directly into the fat to chemically dissolve it. The most common ingredients are phosphatidylcholine and deoxycholate. Neither has been approved by the FDA for this purpose. Vitamins, hormones, and enzymes are often included in the injections. Problems including rashes, ulcers, infections, and contour deformities from uneven fat removal have been reported with this technique.
