What Is HIFU Skin Tightening?
How HIFU Works: Focused ultrasound energy is delivered at specific skin depths (1.5mm, 3.0mm, 4.5mm). The energy heats the tissue to 60–70°C, creating thermal coagulation points. This stimulates fibroblasts to produce new collagen and elastin over time. The SMAS layer (same layer targeted in surgical facelifts) is also tightened when using 4.5mm cartridges.
