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.
- PIH results from abnormal skin pigmentation following an inflammatory response.
- Periorbital syringomas present a unique challenge for laser treatment due to potential pigmentary changes.
