This study aimed to evaluate the effect of the fractional Radiofrequency microneedle treatment for facial atrophic acne scars.
A group of 52 patients were recruited for the study. Goodman & Baron's acne scar grading system was used for assessment at their first visit and the end of 3 months after the last treatment session.
The results displayed that 73.1% of patients have the improvement of the Goodman scar level after four times of treatment. The Goodman and Baron scar point mean was reduced from 16 ± 7.6 to 5.6 ± 5.0 (p < 0.01). Post-inflammatory hyperpigmentation was experienced in 5 patients (9.6%).
The microneedle fractional Radiofrequency is an effective treatment method of facial atrophic acne scars, with minor side effects and a short downtime.
本研究旨在评估微针射频治疗对面部萎缩性痤疮瘢痕的疗效。
招募了一组52名患者进行该研究。在首次就诊时以及最后一次治疗疗程结束后3个月时，使用古德曼和巴伦痤疮瘢痕分级系统进行评估。
结果显示，73.1%的患者在接受4次治疗后古德曼瘢痕等级有所改善。古德曼和巴伦瘢痕评分均值从16±7.6降至5.6±5.0（p<0.01）。5名患者（9.6%）出现了炎症后色素沉着。
微针射频是治疗面部萎缩性痤疮瘢痕的一种有效方法，副作用小，停工期短。
