摘要
背景：黄褐斑是一种慢性复发性皮肤疾病：黄褐斑是一种慢性、复发性皮肤疾病，传统疗法（如氢醌和激光疗法）主要针对表皮成分，而对真皮层的治疗效果有限：评估皮下注射聚d,l乳酸（PDLLA）治疗中度黄褐斑的有效性和安全性：三名菲茨帕特里克皮肤类型 III 型和 IV 型的女性患者（年龄范围：45-59 岁）接受了三次 PDLLA 注射治疗，每次间隔 3 周。治疗结果采用黄褐斑面积和严重程度指数（MASI）进行评估，并在 12 周的随访中进行患者满意度评分：结果：所有患者的黄褐斑面积和严重程度指数（MASI）都有明显改善（减少范围：3.60-6.30 分）。暂时性副作用包括轻度水肿和瘀伤，均在 72 小时内缓解：PDLLA皮下注射在黄褐斑治疗中显示出良好的效果，这可能是由于它对胶原蛋白生成和真皮重塑具有生物刺激作用。还需要进一步研究，包括组织病理学分析，以确认其长期疗效和安全性，并了解其潜在机制。
Efficacy of Subdermal Poly-d,l-Lactic Acid Injections for the Treatment of Melasma.
Background: Melasma is a chronic, recurrent skin disorder with limited long-term treatment success using conventional therapies like hydroquinone and laser treatments, which primarily target epidermal components while leaving dermal aspects untreated.
Objective: To evaluate the efficacy and safety of poly-d,l lactic acid (PDLLA) subdermal injections for treating moderate melasma.
Methods: Three female patients (age range: 45-59 years) with Fitzpatrick skin types III and IV received three PDLLA injection sessions at 3-week intervals. Treatment outcomes were assessed using the Melasma Area and Severity Index (MASI) and patient satisfaction scores at 12-week follow-up.
Results: All patients showed significant MASI score improvements (reduction range: 3.60-6.30 points). Patient satisfaction ratings ranged from 3 to 4 out of 4. Temporary side effects included mild edema and bruising, resolving within 72 h.
Conclusions: PDLLA subdermal injections showed promising results in melasma treatment, potentially due to its biostimulatory effects on collagen production and dermal remodeling. Further research, including histopathological analysis, is needed to confirm long-term efficacy and safety, and understand underlying mechanisms.
