Summary

Photobiomodulation (PBM) effectively reduced postinflammatory hyperpigmentation (PIH) after CO2 laser treatment for periorbital syringomas. This study highlights PBM as a novel prophylactic approach for laser-induced skin dyschromia.

Area of Science:

Dermatology
Laser Therapy
Photomedicine

Background:

Postinflammatory hyperpigmentation (PIH) is a frequent complication of CO2 laser resurfacing, affecting 20-30% of patients.

Keywords:

carbon dioxide laser postinflammatory hyperpigmentation prophylactic photobiomodulation syringoma
