Mesotherapy (Lipo-Dissolve) Mesotherapy involves the injection of certain medications into the mesoderm layer of the skin. Mesotherapy is a very good treatment for localized fat deposits of the chin, saddle bag, abdomen, and thighs. The medication (PC/DC) is used to emulsify and destroy fat cells by destroying the fat cell membrane. Once the mechanism of action occurs, the fat is absorbed back into the body. Phosphatidylcholine (PC) is the active ingredient and each injection covers a treatment area about the size of a quarter. Multiple injections (# of treatments) are required and may not work effectively on older patients, lax skin, and for patients looking for instant gratification. The treatments are very effective but are a series of injections over a period of at least a month. This is one of the most effective treatments for localized fat and results are dependent upon compliance of following through the series of injections. $300 per session.
