Abstract：
Radiofrequency microneedle (RFM) is relatively safe to use for all skin types but there is still possibility of adverse events. Tram-track scarring or uniform papular eruptions is a rarely reported adverse event, but it is challenging to manage. We report a case of successful treatment of tram track scarring post RFM using a combination of light emitting diodes 640 nm and a salicylic acid peel and home treatment with a combination of azelaic acid and retinoic acid. There is still no standard therapy to treat this case. The results of clinical observations showed the lesions completely recovered in 6 months.
摘要：
射频微针（RFM）对于所有皮肤类型都相对安全，但仍有可能发生不良事件。电车道疤痕或均匀的丘疹是很少报告的不良事件。但是管理起来很有挑战性。我们报告了使用640nm发光二极管和水杨酸皮的组合以及使用壬二酸和视黄酸的组合进行家庭治疗，成功治疗了RFM后电车轨道疤痕的案例。目前还没有标准的治疗方法来治疗这种情况。临床观察结果显示病灶在6个月内完全恢复。
