Abstract

Objective: This study aimed to investigate the effectiveness of prophylactic photobiomodulation (PBM) in reducing postinflammatory hyperpigmentation (PIH) induced by carbon dioxide (CO₂) laser resurfacing in a patient with periorbital syringomas. Background: PIH is a common condition characterized by abnormal skin pigmentation after an inflammatory process occurring in up to 20-30% of patients undergoing CO₂ laser resurfacing. Methods: The patient was treated with PBM using a pulsed home-use device at 630 nm before and after CO₂ laser treatment. The patient was asked to treat the right periorbital area before and after the CO₂ laser treatment, which was continued once a day for 2 consecutive weeks. Results: At 12 weeks, PIH was significantly reduced on the treated side compared with the contralateral untreated side (leading to persistent erythema at 6 months). Conclusions: This is the first report of prophylactic treatment of CO₂ laser-induced dyschromia using PBM.

通过预防性光生物调节减少二氧化碳激光诱发的炎症后色素沉着：病例研究。

研究目的本研究旨在探讨预防性光生物调节（PBM）在减少二氧化碳（CO2）激光换肤术诱发的眶周注射瘤患者炎症后色素沉着（PIH）方面的效果。背景：炎症后色素沉着是一种常见病，其特点是皮肤在炎症过程后出现异常色素沉着，在接受二氧化碳激光换肤治疗的患者中发病率高达 20-30%。治疗方法在 CO2 激光治疗前后，使用波长为 630 nm 的家用脉冲设备对患者进行 PBM 治疗。要求患者在 CO2 激光治疗前后对右侧眶周进行治疗，每天一次，连续两周。结果：12 周后，与未治疗的对侧相比，治疗侧的 PIH 明显减少（6 个月后出现持续性红斑）。结论：这是第一份使用 PBM 预防性治疗二氧化碳激光诱发的色素沉着的报告。
