Postacne scarring is an unfortunate and frequent complication of acne, with varied morphological forms and associated significant psychological distress to patients.
To evaluate the efficacy and safety of plasma gel injection alone and in combination with microneedling in treatment of atrophic postacne scars.
Sixty patients with atrophic postacne scars were enrolled in this single blinded randomized controlled study. The patients were divided into three groups with 20 patients being treated with intradermal injection of plasma gel, 20 patients treated with dermaroller, and 20 patients subjected to combined plasma gel and dermaroller. Patients received four sessions at monthly intervals and were evaluated by clinical, histopathological, and immunohistochemical analysis.
There was statistically significant improvement in postacne scars after treatment in all studied groups with variable degrees; the combined technique showed the best clinical improvement in postacne scars. There was an increase in newly formed collagen and elastic fibers with more organized and condensed bundles after the end of treatment.
Plasma gel showed a remarkable improvement for most patients after one session, providing a quick and easy solution for acne scars. The combination of dermaroller and plasma gel potentiated its effect with more improvement in scars.
痤疮后瘢痕是痤疮的一种不幸且常见的并发症,其形态多样,给患者带来明显的心理困扰。
评估单独使用和联合使用等离子体凝胶注射与微针治疗萎缩性痤疮后瘢痕的疗效和安全性。
本单盲随机对照研究纳入了 60 例萎缩性痤疮后瘢痕患者。患者被分为三组,每组 20 例,分别接受真皮内注射等离子体凝胶、微针滚轮和等离子体凝胶联合微针滚轮治疗。患者每月接受 4 次治疗,并通过临床、组织病理学和免疫组织化学分析进行评估。
所有研究组在治疗后痤疮后瘢痕均有统计学意义的改善,改善程度不同;联合技术在改善痤疮后瘢痕方面显示出最佳的临床效果。治疗结束后,新形成的胶原和弹性纤维增加,纤维束更加规则和密集。
单次等离子体凝胶治疗后,大多数患者的痤疮后瘢痕得到显著改善,为治疗痤疮提供了一种快速简便的方法。微针滚轮联合等离子体凝胶治疗可增强其疗效,进一步改善瘢痕。
