Abstract：
UNASSIGNED: Atrophic scarring is a severe form-disfiguring sequela of acne, which can lead to negative effect on patients\' life. Fractional microplasma radiofrequency (RF) has emerged as a promising modality, leveraging dermal fibroblast remodeling to enhance aesthetic results for scars and hyperpigmentation. This study evaluates the efficacy and safety of high-power fractional microplasma RF for atrophic acne scars, considering patient tolerance to procedural discomfort.
UNASSIGNED: In this prospective study, 95 Chinese patients with atrophic facial acne scars underwent three sessions of fractional microplasma RF treatment, with assessments at 1, 3, and 6 months post-treatment. Patients were categorized based on treatment power: Group A (50-70 W) and Group B (70-85 W). Efficacy was determined by three independent dermatologists using digital photographs and Echelle d\'Evaluation Clinique des Cicatrices d\'Acné (ECCA) scores, and patient-reported outcomes gauged satisfaction levels.
UNASSIGNED: Eighty-six patients completed the study. Significant improvements were observed, with a reduction in ECCA scores from 107.21 to 42.27 (P<0.05), demonstrating notable scar amelioration across both groups, albeit with a superior outcome in Group B. All patients experienced transient side effects such as pain, erythema, and edema, deemed tolerable with no long-term adverse effects reported. The treatment was well-received, with high satisfaction rates, underscoring its efficacy and acceptable safety profile.
UNASSIGNED: Fractional microplasma RF therapy, particularly at higher power settings, is an effective and safe option for treating atrophic acne scars, offering significant aesthetic improvement with manageable discomfort. This modality presents a valuable addition to acne scar management strategies, especially for patients with darker skin tones seeking minimal downtime and reduced risk of hyperpigmentation.

摘要：
■萎缩性疤痕是一种严重的粉刺后遗症，这会对患者的生活产生负面影响。分数微等离子体射频（RF）已成为一种有前途的方式，利用真皮成纤维细胞重塑来增强疤痕和色素沉着过度的美学效果。这项研究评估了高功率分数微等离子体射频治疗萎缩性痤疮疤痕的疗效和安全性，考虑患者对程序不适的耐受性。
■在这项前瞻性研究中，95例面部萎缩性痤疮疤痕的中国患者接受了三次分级微等离子体射频治疗，在治疗后1、3和6个月进行评估。根据治疗功率对患者进行分类：A组（50-70W）和B组（70-85W）。疗效由三位独立的皮肤科医生使用数码照片和Echelled'CicatriceCiniqued'Acné(ECCA)评分确定,和患者报告的结果衡量的满意度水平。
■86名患者完成了研究。观察到显著的改善，ECCA评分从107.21降至42.27（P<0.05），这两组都显示出明显的疤痕改善，尽管B组的结果更好。所有患者都经历了短暂的副作用，如疼痛，红斑,水肿,认为可以耐受，没有长期不良反应报告。治疗效果很好,满意度很高，强调其疗效和可接受的安全性。
■部分微等离子体射频治疗，特别是在更高的功率设置下，是治疗萎缩性痤疮疤痕的有效和安全的选择，提供显著的美学改善与可控的不适。这种方式为痤疮疤痕管理策略提供了有价值的补充，特别是对于寻求最短停机时间和减少过度色素沉着风险的较深肤色的患者。
