Abstract
Large-scale long-term retrospective study of noninsulated microneedle radiofrequency treatment on neck rejuvenation is lacking. We conducted a 3-year retrospective observation of subjects treated with noninsulated microneedle radiofrequency (NIMNRF) for neck rejuvenation in Chinese subjects. Of all subjects, 28 subjects (28.6%) received only 1 session of treatment. About 50% subjects achieved ≥ 50% improvement, and average improvements were 37.0% at 3 months follow-up (M3) and 41.6% at 6 months follow-up (M6). Seventy subjects (71.4%) accepted 3 sessions of treatments. The neck aging scores were 3.57 ± 1.28 at baseline, and significantly decreased to 1.10 ± 0.84 at M3 (p < 0.05), 1.04 ± 0.86 (p < 0.05) at M6, separately. The average improvements were 73.3% at M3 and 75.1% at M6. It showed a trend of better efficacy with the increasing number of sessions (p < 0.05). Among of 6 subjects who was followed up for 1 year, 5 subjects who received 3 sessions of treatment achieved about 70% improvement after final session, and another 1 subject who received 1 session remained the improvement up to 40%. The results demonstrate NIMNRF treatment has significant and long-lasting effect on neck laxity and wrinkle reduction with minimal discomfort and downtime.
