What Is HIFU Treatment? How Focused Ultrasound Lifts Skin
HIFU focuses ultrasound energy at precise depths to trigger your skin's own collagen response — no cuts, no needles. Here is how it actually works.
- HIFU (high-intensity focused ultrasound) focuses sound energy at precise depths under the skin — commonly 1.5mm, 3.0mm and 4.5mm — without cutting the surface.
- The 4.5mm depth reaches the SMAS, the same supportive layer tightened in a surgical facelift — but HIFU is not a facelift and does not replace one.
- Each focused point creates a tiny zone of controlled heat that triggers neocollagenesis — new collagen production — over the following months.
