摘要

PURPOSE: A composition for prophylaxis and treatment of skin aging containing a procyanidin oligomer separated from Ulmus macrocarpa, Ulmus pumila, Ulmus davidiana or the like is provided which is safe when applied to the skin, promotes activation of collagen metabolism, improves skin winkles, enhances skin elasticity and inhibits formation of skin wrinkles. CONSTITUTION: This prophylactic and therapeutic composition for skin aging contains 0.001 to 10% by weight of a procyanidin oligomer having an average polymerization degree of 4.5 to 6.0 and 0.001 to 5% by weight of an active oxygen-producing inhibitor, polyethoxylation retinamide derivatives or a mixture thereof, based on the total weight of the composition. The procyanidin oligomer comprises 3 to 12 monomers containing flavan-2-ol as a basic skeleton.
