摘　　要：Maqui berries are wildly grown or cultivated in the Patagonian region in Chile. The berries contain large amounts of anthocyanins, especially delphinidin glycosides, which are strong anti-oxidants. We previously reported that standardized maqui berry extract, which contained lots of anthocyanins, has ameliorative effects against dry eyes and visible light-induced photoreceptor cell damage. However, the influence of maqui berry extract on the human skin has not been evaluated even though many skin troubles are related to active oxygen species.
