Comparing the Safety and Effectiveness of Microfocused Ultrasound: Standard vs Targeted Tissue Protocol in Lifting and Tightening the Lower Face and Upper Neck.

BACKGROUND:Micro-focused ultrasound with visualization (MFU-V) delivers energy to specific soft tissue layers beneath the epidermis with the ability to lift and tighten the lower face and neck.  Objective: To determine the efficacy of microfocused ultrasound with visualization (MFU-V) using a standard treatment line protocol versus a customized treatment line protocol based on the patient's unique anatomy targeting the superficial muscular aponeurotic system and fibrous septae for lifting and tightening of the lower face and neck. METHODS:This was a single-center, prospective, randomized, investigator-blinded clinical trial. 51 subjects were randomized to receive a single treatment of MFU-V targeting the lower face and neck using either a standard or custom treatment protocol.   Results: Subjects in both standard and custom treatment groups noted a greater than one-point improvement in jawline laxity. Three-dimensional photography measurements also demonstrated lifting of the lower face and neck in both treatment groups. CONCLUSION:Custom and standard treatment MFU-V protocols produce a safe and effective treatment for tightening and lifting the lower face and neck. Custom treatment protocols aid in maximizing results for patients with variations in the anatomy of the lower face and neck.  J Drugs Dermatol. 2024;23(4):7647.     doi:10.36849/JDD.7647.
