What is hifu skin tightening?
HIFU (High-Intensity Focused Ultrasound) is a non-invasive skin tightening treatment that delivers focused ultrasound energy to the deep layers of skin (SMAS layer — the same layer targeted in surgical facelifts), stimulating collagen production without cutting the skin. It lifts, firms, and tightens sagging skin on the face, neck, and jawline.
