Body contouring procedures can be divided into liposuction, and excisional procedures. They are not procedures for weight reduction.

Liposuction removes fat through small puncture incisions. Excisional procedures are used when there is a lot of excess skin in addition to fat, such as after significant weight loss. The excess skin needs to be removed otherwise it will hang loose. Incision lines, and hence scars, are longer for these procedures, but there are no effective non-surgical options to improve these conditions.
