Insights on an in vivo model for postinflammatory hyperpigmentation.
The British journal of dermatology
Postinflammatory hyperpigmentation (PIH) can occur following a multitude of inflammatory skin conditions including acne vulgaris. It is more common in darker Fitzpatrick phototypes and represents a common skin complaint in dermatology offices. Despite its common occurrence, treatment options for PIH remain limited. Isedeh et al. published a validated in vivo model for PIH in which 35% trichloroacetic acid (TCA) solution was used to simulate truncal acne-induced PIH. This article is protected by copyright.
