Some pockets of fat stubbornly resist even the most disciplined diet and exercise. Fat-dissolving mesotherapy, or injection lipolysis, targets them directly. A solution based on deoxycholic acid — a substance related to the bile acids your body naturally uses to break down fat — is injected into the unwanted fat, where it disrupts the membranes of the fat cells so their contents are released and gradually cleared away by the body over the following weeks. The treated fat cells are permanently removed, so with a course of sessions the area becomes visibly slimmer and more contoured. It is ideal for smaller, defined areas such as the double chin, bra line, or stubborn flanks, as a non-surgical alternative to liposuction.
