Objectives: To show the pros and cons of microneedle RF approach for melasma based on our various types of several patients treated with microneedle RF at our facility. Introduction: The number of microneedle RF devices in Japan is recently increasing as expected for skin rejuvenation. It can be expected to have a wide variety of therapeutic effects, including improving melasma, redness, and shrinking pores by selectively using a single long pulse (CW: Continuous Wave) that causes thermal coagulation in all layers of the skin, and a multi-short pulse (PW: Pulsed Wave) that selectively causes thermal coagulation in the basement membrane and blood vessels. Materials / method: Our facility introduced pulsed oscillation microneedle RF in 2019, and as of November 2023, we have experienced a total of 54,438 cases. Among them, several noteworthy cases have been extracted for this study. Results: Details of several melasma cases based on our various clinical experiences, for example, melasma improved with microneedle RF alone, melasma improved with oral medication or Q-Switched Nd:Yag Laser Toning, and melasma worsened after microneedle RF, etc. However, there are some points that require caution when using the microneedle RF device during treatment. Conclusion: Microneedle RF has a rejuvenation effect on the skin, helps with vascular disorders, and can be used safely with patients with melasma. Patients with melasma who are worried about enlarged pores or wrinkles can be treated simultaneously with a single device. However, it is important for physicians to be aware of the caution points of microneedle RF.
