Inhibitory effects of the new material obtained from Areca catechu seed (CC-516) according to a special process, and its applicability to the skin as a cosmetic raw material in terms of its efficacy were presented. Areca catechu extract out of 150 medicinal plants, exhibited high inhibitory effect on the porcine pancreatic elastase (IC_{50} : 40.8{mu}g/ml). It also had an inhibitory effect on the human leukocyte elastase (IC_{50} : 48.1mug/ml), hyaluronidase (IC_{50} : 416{mu}g/ml), antioxidative activity (IC_{50} : 45.4mug/ml) and free radical scavenging activity (SC_{50} : 10.2{mu}g/ml). The cream contained 3％ of CC-516 improved skin hydration above 16.5％. Especially, the skin elasticity increases more than 35% and skin wrinkles decreased more than 23％.
