Abstract

BACKGROUND: Radiofrequency microneedling (RFMN) and nonablative fractional 1,550-nm erbium:glass lasers (NAFLs) have been reported to be used with success in neck rejuvenation. There are no head-to-head trials to compare these modalities.

OBJECTIVE: The purpose of the study was to compare the efficacy and safety of radiofrequency microneedling and nonablative fractional 1,550-nm erbium:glass lasers for the rejuvenation of the neck.

METHODS: This was a single-center, randomized, investigator-blinded clinical trial. A total of 21 subjects were randomized into 2 groups, NAFL and RFMN; subjects received 3 treatments 4 weeks apart and were followed up 12 weeks after last treatment.

RESULTS: Subjects in NAFL and RFMN groups showed 42.1% and 8.6% improvement in the Fitzpatrick-Goldman Wrinkling Score, respectively, 41.3% and 16.3% improvement in the elastosis score, respectively. Subjects in the NAFL 1,550-nm erbium:glass group showed significantly better blinded investigator Fitzpatrick-Goldman Wrinkling and Elastosis scores; subjects in the RFMN groups showed a more significant reduction in the Horizontal Neck Wrinkle Severity Score. There was a trend for higher patient satisfaction with the NAFL.

CONCLUSION: This study showed that both treatments resulted in significant improvement in wrinkling and elastosis scores; the NAFL treatment was associated with significantly better blinded investigator Fitzpatrick-Goldman Wrinkling and Elastosis scores and better subject satisfaction.
