Mesotherapy is used to treat several conditions, including cellulite, localized fat deposits, facial and neck wrinkles, acne, hair loss and stretch marks. Injections of various natural or synthetic compounds are introduced with a tiny needle into the mesoderm, or layer of fatty and connective tissue immediately below the skin. Most people are able to tolerate the slight pain felt during an injection. For people with a low pain threshold, injections can be given under local anesthesia.

Mesotherapy is thought to improve the appearance of cellulite, or superficial fat deposits, through several complementary mechanisms. Fat cells are broken down, new fat is prevented from forming, damaged connective tissue that creates the dimpling effect is broken down, and blood circulation is improved. The end result is a smoothening of the skin.

To treat more localized fat deposits, such as love handles, a compound called phosphatidlycholine is commonly injected. This compound is a good fat that is naturally produced by the body. When injected into an area with excess fat, it acts by stimulating the removal of stored fat, and blocking the deposition of newly formed fat.

Mesolifts, or facelifts using Mesotherapy, involve the injection of vitamins below facial and neck skin. These vitamins are thought to stimulate the formation of collagen and elastin, two proteins make skin elastic and firm, and to also improve skin circulation. Similar treatments can be used for other parts of the body where the skin can develop wrinkles or may sag, such as the neck and hands.

The benefits of Mesotherapy include minimal invasiveness and no recovery time. Since very small amounts of drugs or other substances are injected, the potential for side effects may be substantially reduced. However, like any other treatment, Mesotherapy can have side effects. Bruising, allergies and infection are some possible side effects.
