Dual-approach High-intensity Focused Ultrasound for Facial Contour Modulation and Submental Reduction

Area of Science:

• Aesthetics
• Dermatology
• Medical Devices

Background:

• Facial aging causes region-specific volume loss and excess.
• Targeted energy delivery is crucial for effective facial rejuvenation.
• Dual-mode high-intensity focused ultrasound (HIFU) allows for precise remodeling of facial tissues.

Purpose of the Study:

• To evaluate the effectiveness of compartment-programmed dual-mode HIFU for facial and submental contouring.
• To assess region-specific volume changes and aesthetic outcomes after HIFU treatment.
• To determine patient satisfaction and safety of the dual-mode HIFU procedure.

Main Methods:

• A prospective case series involving 38 Korean adults.
• Single session of compartment-programmed dual-mode HIFU across 7 facial and submental zones.
• Outcomes measured using 3D stereophotogrammetry, cervicomental angle, jawline definition, and Global Aesthetic Improvement Scale.

Main Results:

• Significant improvements in cervicomental angle (+6.4°) and jawline definition (+17.1%) (P < 0.001).
• Intention-consistent volume changes observed: microaugmentation in central perioral-marionette zones and volume reduction in lateral facial and submental areas.
• 93.7% of participants rated as "improved or better" on the Global Aesthetic Improvement Scale at 12 weeks, with high satisfaction (4.5/5).

Conclusions:

• Compartment-programmed dual-mode HIFU effectively achieves coordinated, zone-specific facial and submental contour changes.
• The treatment demonstrates potential for non-invasive facial rejuvenation.
• Further studies are needed to confirm long-term durability beyond initial remodeling.
