摘要氨基酮戊酸光动力疗法（ALA-PDT）是一种安全、有效的痤疮物理治疗方法，已广泛应用于临床。为进一步规范ALA-PDT在痤疮治疗中的临床应用，本共识在2011版《5-氨基酮戊酸光动力疗法治疗寻常痤疮的共识》基础上，围绕其作用机制、患者选择、治疗参数、操作流程以及治疗反应的处理等多方面进行规范，从临床角度提供ALA-PDT治疗痤疮的操作管理及参数建议。

abstractsAminolevulinic acid-based photodynamic therapy (ALA-PDT) is a safe and effective physical therapy for acne, and has been widely used in clinical practice. In order to further standardize the clinical application of ALA-PDT in the treatment of acne vulgaris, this consensus summarizes its mechanisms of action, and standardizes the patient selection criteria, treatment parameters, operating process and management of adverse reactions based on the 2011 version of consensus on ALA-PDT for treatment of acne vulgaris. This consensus also provides suggestions on ALA-PDT operation protocols and parameters for the treatment of acne from a clinical perspective, aiming to provide principles and guidance for clinical application of ALA-PDT in acne treatment.
