Ultrasound Technologies Expand Role in Noninvasive Facial Rejuvenation

Ultrasound-based energy devices continue to play an expanding role in noninvasive facial and neck rejuvenation, according to a recent review published online in Facial Plastic Surgery. The authors examine the evolution of high-intensity focused ultrasound (HIFU) into newer technologies such as microfocused ultrasound with visualization (MFU-V) and synchronous ultrasound parallel beam (SUPERB) systems.

Facial and cervical aging are described as multilayered processes involving structural descent, reduced collagen production, and increased collagen degradation, contributing to rhytids and skin laxity. Ultrasound-based platforms are designed to address these changes by delivering controlled thermal energy to specific tissue depths. MFU-V enables real-time visualization and targets the deep dermis and superficial musculoaponeurotic system (SMAS) at depths ranging from 1.5 to 4.5 mm, while SUPERB technology delivers energy at a fixed depth of approximately 1.5 mm to the mid-dermis.

The review highlights patient selection as a key determinant of outcomes, noting that these modalities are best suited for individuals with mild to moderate skin laxity seeking gradual tightening and textural improvement without surgical intervention. Treatment approaches vary depending on device and transducer selection, with MFU-V allowing for multi-depth protocols and SUPERB offering more uniform energy delivery.

Postprocedure effects are typically limited to transient erythema and edema, with standard aftercare focused on photoprotection. The authors also point to emerging interest in combining ultrasound technologies with regenerative modalities, although data remain limited.
