Tightening and Reduction of Unwanted Submental Fat Using Triple-Layer High-Intensity Focused Ultrasound: Clinical and...

Area of Science:

• Aesthetics
• Dermatology
• Medical Devices

Background:

• Submental fat (SMF) is a common aesthetic concern.
• Current reduction methods are often invasive or lack robust evidence.

Purpose of the Study:

• To evaluate the safety and efficacy of a novel triple-layer high-intensity focused ultrasound (HIFU) regimen for SMF reduction.

Main Methods:

• Forty Korean subjects with moderate to severe SMF received a single session of triple-layer HIFU treatment.
• Treatments utilized 3.0-, 4.5-, and 6.0-mm focusing transducers.
• Evaluations included the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS), Subject Self-Rating Scale (SSRS), and 3D imaging at 8 weeks.

Main Results:

• 62.5% of subjects were classified as treatment responders (≥1-point improvement in CR-SMFRS).
• 67.5% of patients reported satisfaction with their facial and chin appearance (SSRS score ≥4).
• 3D imaging corroborated clinical findings, and observed side effects were mild and transient.

Conclusions:

• The triple-layer HIFU regimen, including a 6.0-mm transducer, offers benefits for submental fat reduction.
• This approach demonstrates efficacy in tightening and rejuvenating the submental area.
• The treatment shows a favorable safety profile for addressing unwanted submental fat.
