Handheld microfocused ultrasound device for facial lifting: A preliminary study of ULTIGHT.

Objective: Although focused ultrasound modalities have achieved positive clinical results in noninvasive skin rejuvenation, they presented various side effects and particularly severe pain during treatment. This study introduces a microfocused ultrasound (MFU) device, ULTIGHT, to overcome the severe pain issue, providing quasi-facial lifting.

Materials And Methods: Transducer surface was imaged with a scanning electron microscope.
