Photodynamic therapy (PDT) has been considered a safe and efficacious treatment for actinic keratoses (AKs) of the scalp and face. The procedure involves exposing a patient to a blue light source 1-4 hours after application of photosensitizing aminolevulinic acid (ALA) at a dose of 10 J/cm2 for up to 1000 seconds.(1,2) We suggest that amount of exposure time and area of exposure should be stratified according to baseline photodamage.
光动力疗法（PDT）被认为是治疗头皮和面部光化性角化病（AKs）的一种安全有效的方法。该程序包括在以10 J/cm²的剂量应用光敏氨基乙酰丙酸（ALA）后1至4小时，将患者暴露于蓝光光源下长达1000秒。（1,2）我们建议，暴露时间和暴露面积应根据基线光损伤情况进行分层。
