PIH
Also written as: PIH — post-inflammatory hyperpigmentation
Post-inflammatory hyperpigmentation; darkening of skin following inflammatory conditions, particularly common in darker-skinned children.
Full Definition
Post-inflammatory hyperpigmentation (PIH) represents increased melanin production following inflammatory skin conditions such as acne, eczema, or infections. In pediatric dermatology, PIH is particularly prevalent in children with darker skin types and can persist for months to years. The condition can be more psychologically distressing than the original inflammatory process, especially in adolescents. Medical writers must understand that PIH prevention through early treatment of inflammatory conditions is more effective than subsequent therapy, and should emphasize sun protection in management discussions.
