Injection lipolysis chemically reduces the number of fat cells around the injection site. The chemical, called deoxycholic acid, results in fat cell disruption and death. Lipolysis is most commonly used to treat the chin and face. This procedure is also highly effective when used in the arms, back, thighs and stomach. At Skin ‘n Smiles, we offer Kybella, which has been shown to be especially effective for the treatment of the area underneath the chin to eliminate what is known as a “double chin.”
