HIFU (High-Intensity Focused Ultrasound) is a non-invasive skin tightening and lifting treatment that uses focused ultrasound energy to penetrate deep layers of the skin without damaging the surface. It stimulates natural collagen production, helping to lift sagging skin, reduce wrinkles, and improve overall skin firmness. Often called a non-surgical facelift, HIFU delivers gradual, natural-looking results with minimal downtime.
