High-Intensity Focused Ultrasound (HIFU) is a popular, non-invasive cosmetic procedure used to tighten and lift facial skin without surgery or downtime.
How HIFU Works for Face Lifting
HIFU delivers focused ultrasound energy deep into the SMAS layer (Superficial Musculoaponeurotic System), which is the same layer targeted in a surgical facelift.
This thermal energy heats the tissues to about 60–70°C, causing controlled micro-injury that triggers:
Collagen production
Tissue tightening and lifting
Over time (typically 2–3 months), the skin becomes firmer, lifted, and smoother.
