“…The demand for noninvasive esthetic procedures for skin tightening has increased. Technologies other than microfocused ultrasound, calcium hydroxyapatite, and botulinum toxins, such as radiofrequency (RF) [6][7][8][9][10], high-intensity focused ultrasound (HIFU) [11,12], laser [13], and pressure energy devices, which have been discussed in previous studies, improve the aesthetic appearance and self-confidence of patients. Nevertheless, while there have been studies combining microfocused ultrasound and calcium hydroxyapatite to treat abdominal skin laxity, there has never been any research combining microfocused ultrasound, calcium hydroxyapatite, and botulinum toxin to treat abdominal skin laxity.…”

Background: After significant weight loss, the abdominal skin can become permanently stretched, resulting in stretch marks, laxity, and thinning of the dermis. For many patients, surgical methods such as abdominoplasty are too risky due to the potential for complications, the lengthy recovery period, and the high cost. Objective: The purpose of this pilot study was to use microfocused ultrasound, calcium hydroxyapatite, and Incobotulinum toxin A to improve the appearance of patients who were suffering from abdominal skin laxity after heavy weight loss. The combination of these treatments can provide comprehensive results with minimal downtime and lower risk compared to traditional surgical procedures. Methods: Our team treated four female Chinese patients with microfocused ultrasound, diluted calcium hydroxylapatite, and Incobotulinum toxin A with different combinations, respectively. The first and second cases were only treated with 810 shots of microfocused ultrasound. The third case received 850 shots of microfocused ultrasound plus 5 mL of diluted calcium hydroxylapatite and 50 units of Incobotulinum toxin A on the left abdominal skin, and the fourth case was treated with 900 shots of microfocused ultrasound plus 5 mL of diluted calcium hydroxylapatite and 10 units of Incobotulinum toxin A on the left abdominal skin. All four patients received a single treatment session. Clinical photographs were taken before each treatment, and two individual blinded investigators were asked to assess photographs taken after 4 weeks and compare them with the pretreatment photos. Results: All four cases showed an overall clinical improvement, with the third and fourth cases demonstrating more significant skin tightening based on photographic analysis. The data indicate that the inclusion of calcium hydroxylapatite and Incobotulinum toxin A in microfocused ultrasound treatment yields superior results for abdominal rejuvenation. Conclusions: Abdominal skin laxity can be treated with a triple therapy combining microfocused ultrasound, diluted calcium hydroxylapatite, and Incobotulinum toxin A.

“…Each of the five equally sized portions of the NLF received an energy density of 8 J/ cm 2 . 30 The energy density in the upper portion of the NLF next to the alar cartilage was doubled to 16 J/cm 2 . 31 Since it has been demonstrated that the Levator labii superior and zygomaticus muscles are involved in the formation of NLF prominence with ageing, these muscles also received 8 J of energy.…”

Introduction: Biomechanical qualities of the skin tissue change following numerous pathological and natural (ageing) conditions. The best skin treatments are those resulting in a positive outcome with the fewest adverse effects. In this study, high-frequency ultrasonography (US), which provides a quantifiable scale, was utilized to evaluate the impact of a 2-W laser on characteristics of nasolabial fold (NLF) including depth and area, epidermis and dermis thicknesses, and Young’s modulus (YM). Methods: Nine female subjects (54.09±0.09 years old) with Fitzpatrick skin types III-IV and five young control participants (26±1.28 years old) for providing the control data were included in this study. Laser therapy was applied twice weekly for seven consecutive sessions. A class IV laser with 810-nm and 980-nm wavelengths, 2-W power, and 25-Hz frequency was applied twice a week for seven consecutive sessions. The energy administered had a density of 8 J/cm2 . An evaluation using high-frequency ultrasound (40 MHz) was accomplished before and 48 hours after the final treatment session. The Face-Q questionnaire was used to assess the patient’s perspective on this procedure. Results: For each US parameter, the intraclass correlation coefficient was high (ICC>0.9). After the laser treatment, NLF depth, area, epidermis, dermis, YM, and Face-Q significantly improved compared to baseline (P<0.05). Conclusion: For the assessment of skin tissue, high-frequency US is a reliable technique. The 2-W laser is a safe, effective, and non-invasive procedure for enhancing skin features.
