The discussion centers on non-invasive body contouring methods for skin tightening and cellulite improvement without surgery. One established technique is SoftWave Superb, which uses ultrasound technology to tighten skin on the face, buttocks, and stomach, offering consistent results with less pain. A newer method, carbon wave laser treatment, involves applying a topical carbon suspension to the skin and activating it with lasers. This innovative approach has shown dramatic results in skin tightening for the buttocks and thighs, and also effectively treats cellulite dimples.
