Injectable Body Contouring is used for the enlargement and enhancement of the breasts, calves and buttocks and also for evening out discrepancies in skin surface such as those sometimes caused by liposuction. The first body shaping and volume restoration product which uses hyaluronic acid to achieve this is called Macrolane™ VRF which is no longer indicated for breasts. Treatment involves a small incision in the area and the injection of the substance using a thin cannula or large gauge needle. Due to the fact that the body will metabolise the hyaluronic acid over time, yearly top-ups are required to maintain the optimal results, which should last 12 - 18 months. The quantity required at top-ups may reduce over time. Private costs for injectable body contouring treatment depends on the type and size of the area(s) being treated, such as breast or buttock reshaping and the amount of product required. Typically an initial breast injection treatment will cost in the region of £2,500 - £3,000, with top-up treatment in a year's time in the region of £1,400.
