Vaser chin and neck liposuction is a surgical procedure that uses ultrasound energy to break up and remove fat from the chin and neck areas. The ultrasound energy is delivered through a small cannula (a thin tube) inserted into the treatment area. This energy causes the fat cells to liquefy, making them easier to remove. The procedure is typically performed under local anesthesia; recovery time is usually short. This procedure aims to create a more defined jawline and a slimmer, more youthful-looking neck.
