Skin aging was a complex and continuous process that affected skin functions and appearance. The natural berry extract had antioxidant activity, can capture the superoxide free radicals and hydroxyl free radicals generated by ultraviolet light, so it can prevent skin aging. Several kinds of berries, including grapes, pomegranate, black currant, black chokeberry, to produce multi-berry favor drink. We used multi-berry favor drink to treated B16/F10 cells with blue light to examine melanin and antioxidant ability. Moreover, 40 adult subjects were recruited, and drink daily for 8 weeks, then examine skin condition. The multi-berry favor drink significantly decreased the melanin formation compared with the blue light group in vitro. After taking 8 weeks, the multi-berry favor drink significantly increased SOD activity, and slight increased total antioxidant capacity in human plasma. Multi-berry favor drink significantly improved the collagen, spots, melanin, wrinkles, texture and pores in the facial skin. Taking multi-berry favor drink for 8 weeks can improve the collagen, spots, melanin, wrinkles, texture and pores of the skin. In addition, multi-berry favor drink can increase the capacity of antioxidant and decrease the melanin production.
