Treatment of Epilation-Related Postinflammatory Hyperpigmentation Using a 1,927-nm Thulium Fiber Fractional Laser

Abstract

Postinflammatory hyperpigmentation (PIH) is a common problem after cosmetic procedures and successful treatment of PIH remains challenging. We report the case of a 33-year-old man who presented with hyper-pigmented skin lesions on his legs that persisted for 6 months following laser hair removal. We used a 1,927-nm thulium fiber laser to treat the lesions, resulting in near complete resolution after five sessions over a 1 month interval.
