Step World Co., Ltd., a Tokyo (Shibuya-ku) based company that develops and sells beauty and health products, has launched a new addition to its URUHIME MOMOKO skincare line. From September 10, 2026 (Thursday), URUHIME MOMOKO COMPLETE SERUM is available at Watsons Taiwan, one of Taiwan's largest drugstore chains, and on momo shopping site, one of Taiwan's largest online shopping platforms.
An Exosome-Focused Serum
URUHIME MOMOKO COMPLETE SERUM is the newest model in the URUHIME MOMOKO beauty serum series, built around exosomes, an ingredient category drawing attention in next-generation skincare. The formula features plant-derived Lycium Chinense Callus Culture Extract, fullerene, and niacinamide as key moisturizing ingredients, aiming to address skin concerns and needs that change with age and life stage.
Since it's a product used daily, the formula is also designed to be free of seven common irritants: mineral oil, alcohol, silicone, UV absorbers, fragrance, coloring agents, and petroleum-based surfactants.
A Trusted Brand in Taiwan
URUHIME MOMOKO already enjoys strong brand recognition and support in the Taiwan market. At Watsons, one of Asia's largest drugstore chains, the brand has built a track record of results, including the WATSONS 2023 Health and Beauty Award (Best Sales Award) for its URUHIME MOMOKO supplement, and the WATSONS 2025 Health and Beauty Award (Best Seller Award) for its URUHIME MOMOKO S1 Serum. With URUHIME MOMOKO COMPLETE SERUM now joining the lineup, the brand can respond more broadly to skin concerns and needs that shift with age and life stage, for existing customers and new customers alike.
Under the brand concept of achieving "beautiful skin without trying too hard," URUHIME MOMOKO plans to keep expanding its product lineup so customers can choose what suits them, while growing its distribution across markets worldwide.
