Abstract: Vitiligo is a common depigmentation disorder,and its treatment remains a challenge.Placenta preparations contain proteins/peptides with molecular weight greater than 3000 and sphingolipids,which can induce melanogenesis through p38 MAPK and promote proliferation and difierentiation of melanoblasts.It has been demonstrated that placenta preparations are a safe and effective treatment with few adverse reactions for vitiligo,especially for childhood vitiligo affecting the scalp.
