The Effectiveness of Microneedle Bipolar Fractional Radiofrequency in Treating Neck Wrinkles

ABSTRACT Introduction Wrinkles, particularly in the neck area, are a prominent sign of aging. In recent years, there has been an increasing demand for neck wrinkle treatment. Previous studies have demonstrated that microneedle bipolar fractional radiofrequency is effective for facial wrinkles, with minimal side effects. This has led to interest in utilizing microneedle bipolar fractional radiofrequency for treating neck wrinkles as a potentially effective and safer option. Objective To evaluate the effectiveness and safety of microneedle bipolar fractional radiofrequency in the treatment of neck wrinkles. Methods This pilot study involved 25 subjects with neck wrinkles, classified at level II‐III on the Fitzpatrick wrinkle assessment scale, with scores of 4 or higher. Each participant received two treatments of microneedle bipolar fractional radiofrequency, spaced 12 weeks apart. The primary outcome measures included physician‐assessed photographic comparisons and evaluations using the Global Aesthetic Improvement Scale (GAIS). Secondary outcomes included patient satisfaction and the occurrence of side effects. Satisfaction was measured via a questionnaire at 12 and 24 weeks post‐treatment, with any adverse effects also being documented. Results The study involved 25 participants, comprising 23 females and 2 males. After the first treatment (12 weeks post‐treatment), photographic evaluations and GAIS scores showed that 19 participants (76%) experienced mild improvement, while 6 participants (24%) exhibited significant improvement. Following the second treatment (24 weeks post‐treatment), 13 participants (52%) showed mild improvement, 11 participants (44%) demonstrated significant improvement, and 1 participant (4%) reported marked improvement. Participant satisfaction was notably high, with an average score of 8.64 ± 0.76 out of 10 at 12 weeks, rising to 9.08 ± 0.76 at 24 weeks. Reported side effects included transient erythema in 96% of participants (resolving within 24–48 h), pruritus in 28% (resolving within 1–3 days), and small scabs in 40% (resolving within 3–5 days). No serious adverse effects, such as hyperpigmentation, folliculitis, or scarring, were observed. Conclusion Microneedle bipolar fractional radiofrequency is a highly effective and safe treatment for neck wrinkles.
