Use of Ultrasound in Face and Neck Rejuvenation

To review the current state of ultrasound energy-based devices and their role in facial and neck rejuvenation.

High-frequency ultrasound (HIFU) paved the way for the micro-focused and parallel beam ultrasound technology in aesthetics.

Facial and cervical aging reflect multilayered structural changes, as well as reduced collagen production and increased collagen breakdown at the histologic level, resulting in rhytids and skin laxity.

Micro-focused ultrasound with visualization (MFU-V) is adapted from HIFU, using significantly less ultrasound energy and visualization to precisely target the deep dermis and superficial musculoaponeurotic system (SMAS) at depths ranging from 1.5 to 4.5 mm; synchronous ultrasound parallel beam (SUPERB) technology uses parallel transducers to deliver energy at a precise depth of 1.5 mm to target the mid-dermis.

Ultrasonic facial rejuvenation is ideal for those with mild to moderate skin laxity who desire incremental tightening and textural improvement without surgery.

MFU-V can be performed at different tissue depths based on the transducer tip, with various combination protocols described; SUPERB technology delivers energy at a fixed depth.

Self-limited erythema and edema, sun protection.

The intersection of ultrasonic devices and regenerative medicine is promising.

MFU-V and SUPERB are ideal noninvasive options for patients with mild to moderate skin laxity.
