HIFU
Pronunciation: HY-fyoo
Also written as: HIFU — High-Intensity Focused Ultrasound
High-Intensity Focused Ultrasound; a non-invasive energy-based treatment that delivers focused ultrasound waves to the superficial musculoaponeurotic system and deep dermis to induce tissue tightening.
Full Definition
HIFU (High-Intensity Focused Ultrasound) targets specific tissue depths—typically 1.5 mm, 3.0 mm, and 4.5 mm—using focused ultrasound energy to create discrete thermal coagulation points. The resulting wound-healing response stimulates collagen production and leads to gradual tissue lifting and tightening. It is commonly used for non-surgical brow lifting, neck tightening, and décolletage rejuvenation. In editorial contexts, the acronym HIFU must be expanded on first use in clinical and marketing documents. The proprietary device name 'Ultherapy' is sometimes incorrectly used as a generic term and must be corrected.
Usage
Usage note: Always expand on first use. Do not use the brand name 'Ultherapy' as a synonym in non-branded clinical content.
