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. Keywords NIMNRF . Neck rejuvenation
Introduction Skin aging presents coarse rhytides, sallowness, roughness, loss of burnish and resiliency, abnormal pigmentation, and telangiectasias. Histology characterizes mainly atrophic or hyperplastic epidermis, in dermis fragmented collagen and dysfunctional glycosaminoglycans and proteoglycans [1–4]. Genetics, dysregulation of the extrinsic and environment such as ultraviolet irradiation, air pollution, toxic detergent, and improper use of cosmetics may be related to skin aging [5, 6]. Regardless of age and skin type, the demand for

esthetic nonsurgical treatment to keep skin rejuvenation is increasing. Esthetic improvement of aging neck becomes one of the most challenging aspects. Pharmacotherapy and intensepulsed light (IPL) therapies are commonly applied for skin rejuvenation treating without scarring, whereas insufficient for tightening skin. Several other nonsurgery methods have been recommended, such as deep chemical peeling, ablative or nonablative laser resurfacing, radiofrequency (RF), intense focused ultrasound, and botul
