Official Title: An In Vivo Model for Postinflammatory Hyperpigmentation: Part II
Brief Summary: Post-inflammatory hyperpigmentation (PIH) is an acquired hypermelanosis that occurs after cutaneous inflammation or injury that frequently affects darker skinned populations. Previously, a model of 35% TCA-induced PIH was validated against acne induced PIH, which has value in product testing for the treatment of PIH. In this second phase of the study, the investigators would like to determine if a lower concentration of TCA-induced PIH is comparable to acne-induced PIH.
