Abstract

BACKGROUND Patients commonly complain about the appearance of acne scars. While various lasers and energy-based devices can offer clinical improvement, many of them are limited in treating patients with skin of color. Concerns exist regarding efficacy and safety, including risks of scarring, prolonged dyspigmentation, necrosis, and burns. OBJECTIVE To examine the utility of a 755-nm picosecond laser with fractionated lens array in improving the clinical appearance of acne scars in patients with Fitzpatrick skin types V and VI. MATERIALS AND METHODS A prospective clinical study investigated this laser using up to 5 monthly treatments. RESULTS Twenty-four subjects were enrolled, while 17 subjects completed a 3-month follow-up. The mean age was 33.9 years, and 95.8% of the subjects were women. Fitzpatrick skin types V and VI were represented. Assessments compared baseline to 3-month follow-up. Two of the 3 blinded reviewers agreed on identifying pretreatment and post-treatment photographs for 82.4% of the cases. For physician Global Aesthetic Improvement Scale, 100% of the subjects had clinical improvement. Overall, 94.1% of subjects were satisfied with their treatment. No serious or unanticipated adverse events occurred. CONCLUSION A 755-nm picosecond laser with fractionated lens array can safely and effectively improve acne scars in patients with Fitzpatrick skin types V and VI.

采用衍射透镜阵列的 755 nm 皮秒激光治疗 Fitzpatrick V 型和 VI 型皮肤的痤疮疤痕。

背景：患者通常会抱怨痤疮疤痕的外观。虽然各种激光和能量设备可以改善临床症状，但其中许多设备在治疗有色皮肤患者时效果有限。目的研究 755 nm 皮秒激光器与分型透镜阵列在改善菲茨帕特里克皮肤 V 型和 VI 型患者痤疮疤痕临床外观方面的效用。材料和方法前瞻性临床研究调查了这种激光器，最多每月治疗 5 次。受试者的平均年龄为 33.9 岁，95.8% 为女性。菲茨帕特里克皮肤类型为 V 型和 VI 型。评估比较了基线和 3 个月的随访。在 3 位盲审者中，有两位对 82.4% 病例的治疗前和治疗后照片的识别达成了一致。在医师全球美学改善量表中，100%的受试者都有临床改善。总体而言，94.1% 的受试者对治疗表示满意。结论755nm皮秒激光配合分型透镜阵列可以安全有效地改善菲茨帕特里克皮肤类型V型和VI型患者的痤疮疤痕。
