Abstract

Background: Fractional technology overcomes several problems of ablative lasers such as a high incidence rate of post- inflammatory hyperpigmentation (PIH). A new technology fractional radiofrequency, which induces deep dermal heating and leaves the epidermal less affected results in less adverse effect in Chinese. Objective: To evaluate the efficacy, safety and tolerance of fractional bipolar radiofrequency (RF) in the treatment of acne scars in Asian people with the strategy of high energy. Methods: Twenty-six healthy Asian patients with acne scars received four monthly high energy (85–95mj/pin) treatments with a fractional bipolar RF device. Improvement and tolerance were evaluated at each treatment and a 4-week and 12-week follow-up visit. Results: Twenty-three patients completed the study. Acne score showed a significantly decrease at 4-week and 12-week follow-up visits. Patients’ evaluation of global improvement and satisfaction increased at the 12-week visit compared with baseline. Side effects were limited to transient pain, erythema, dryness and low risk of PIH. Conclusion: Treatment with high energy of fractional bipolar RF is safe and effective for acne scars in Asian people. Common side effects such as PIH, eschars are less than fractional lasers.
