HIFU (High-Intensity Focused Ultrasound) Body is a non-surgical treatment that uses focused ultrasound energy to lift, tighten, and contour the skin. It targets the SMAS (Superficial Musculo-Aponeurotic System) layer by delivering precise thermal energy at depths of 6mm to 13mm, stimulating natural collagen production and tissue regeneration. This results in gradual, long-lasting rejuvenation without downtime, effective for both facial tightening and body contouring.
