Patent ID: 8426383

Claim:
A composition for external use on skin, which comprises 15 to 70 wt. % of low-molecular weight hyaluronic acids, 15 to 60 wt % of high-molecular weight hyaluronic acids, and 15 to 60 wt % of polysaccharides extracted from root bark of Ulmus davidiana , as active ingredients, wherein the weight is based on the total weight of the composition, wherein the high-molecular weight hyaluronic acids have an average molecular weight of 500,000 Da to 3,000,000 Da, and the low-molecular weight hyaluronic acids have an average molecular weight of 500 Da to 50,00 Da, and wherein skin treated with the composition demonstrates an increased skin elasticity-enhancing effect as compared to skin treated with a composition including only one of low-molecular weight hyaluronic acids, high-molecular weight hyaluronic acids, or polysaccharides extracted from root bark of Ulmus davidiana.
