Extract
The author should be congratulated on both the design and content of this excellent study.1 The focus on the regenerative nature of microfocused ultrasound (MFU) is timely. Hausch and Dobke’s recent paper2 showed that a survey of 12 plastic surgeons rated regenerative medicine as the top-ranked category of interest of both patients and aesthetic physicians. Although aesthetic medical device-based procedures in general seem to follow trends and may fall out of favor, the MFU procedure has proved to have retained value since its introduction almost a decade ago. Although the duration of clinical effects has not been studied beyond 6 months,3 my patients have commented that they see results at the 5-year mark or beyond.
The limitations of botulinum toxin and fillers are well noted. As a practitioner’s patient population ages, he or she may note that “filler fatigue” is a common occurrence. A patient treated some years ago with 2 syringes of filler now notes that she needs 4 syringes per session to achieve the same effect. Dissatisfaction in the filler and toxin patient population is not uncommon, as many expect visible and lasting effects from a treatment for at least a year.
