Background:
Neck rejuvenation has consistently become a popular cosmetic procedure. While various treatment modalities have been used, a novel fractional thermomechanical skin rejuvenation system was recently developed to create dermal coagulation through direct heat transfer with subsequent neocollagenesis.
Objective:
A prospective clinical trial evaluated the efficacy and safety of a thermomechanical fractional injury device (Tixel 2, Novoxel, Netanya, Israel) for neck rhytides.
Materials And Methods:
Subjects with moderate to severe neck rhytides were enrolled for 4 monthly treatments.
Results:
Twenty-six subjects were enrolled and completed all study visits. The mean age was 58.4 years, and 100.0% were women. Fitzpatrick skin types I to IV were included. For Fitzpatrick Wrinkle Classification System (FWCS), the mean baseline score was 6.3. As per investigator, there was a mean 1.5-grade improvement in FWCS at 1-month follow-up ( p < .00001) and 1.4-grade improvement in FWCS at 3-month follow-up ( p < .00001). For physician Global Aesthetic Improvement Scale, all subjects (100%) had improvement at both 1- and 3-month follow-up visits. There were no severe adverse events, and subjects experienced minimal pain.
Conclusion:
A novel thermomechanical fractional injury device is effective and safe for the treatment of neck rhytides.
