Neck liposuction can be a critical step towards creating the refined, feminine contour that telegraphs your chosen gender identity. During liposuction, stubborn, unwanted fat from beneath the chin is removed using a slim cannula, or suction device. The fat is then discarded as waste, or is saved for use as part of a facial fat transfer treatment. It is oftentimes performed in conjunction with mandible contouring and genioplasty.
