Hair Aging Care Through Joint Research with RIKEN and Other Institutions

「当社は今後も北海道大学との共同研究を通じて、細胞レベルから肌や毛髪の機能にアプローチする化粧品技術の創出に取り組んでまいります。」

「Through joint research with Hokkaido University, Ajuban Cosme Japan Co., Ltd. identified a new useful raw material that promotes the repair of mitochondrial DNA damage associated with aging and presented the findings at the 145th Annual Meeting of the Pharmaceutical Society of Japan in Fukuoka, held from 27 to 29 March 2025 at the Fukuoka International Congress Center. The findings may lead to the control of skin aging at the cellular level, and the Company will proceed with developing aging-care cosmetics and scalp-care products containing the raw material.」

「At the 27th Annual Meeting of the Japanese Society of Clinical Hair Research held in November 2022, under the title “The Potential of New Hair-Growth Ingredients from the Perspective of Regenerative Medicine Researchers,” Takashi Tsuji of the Organogenesis Research Team at RIKEN's Center for Biosystems Dynamics Research reported evidence on a new hair-growth ingredient discovered through joint research, while Akio Sato of Tokyo Memorial Clinic reported the results of a clinical study of a hair-growth product containing the new ingredient.」

「The Company presented research findings on sphingolipids, one of several hair-growth-promoting ingredients discovered by the joint research team of the Group and RIKEN, at the 296th Tokai Regional Meeting of the Japanese Dermatological Association held in June 2021. In addition, after six years of joint research, it began selling the NUOSS men's hair-growth-care series, developed by focusing exclusively on what is necessary to establish a foundation for men's hair-growth care through an in-depth understanding of men's hair and life cycles, via its brand website and other channels on 5 October 2021.」

「Hair-care product sales continued to perform well and exceeded the previous fiscal year's level, even though one year had passed since the launch of KASUI, introduced in the previous fiscal year. As a result, sales for the cumulative first three quarters of the current fiscal year were ¥2,326 million, up 10.5% year on year.」

「Hair-care product sales exceeded the previous fiscal year's level, partly because KASUI, launched in the previous fiscal year, continued to perform well.」

「Hair-care product sales exceeded the previous fiscal year's level, partly because KASUI, launched in the previous fiscal year, performed well. As a result, sales for the first quarter of the current fiscal year were ¥742 million, up 26.5% year on year. KASUI KASUI is a new hair-care brand for which the Company identified functional ingredients through joint research with RIKEN and subsequently developed its own formulation.」

「The Company announced at an academic conference hosted by JSCHR (the Japanese Society of Clinical Hair Research) in November 2020 that the functional peptide discovered by the joint research team of the Company and RIKEN has hair-growth-promoting effects. It has also filed a patent application.」

「In October last year, we launched KASUI as a new haircare brand and Jalire as a system treatment.」

「Through joint basic research with RIKEN, the Company identified functional ingredients related to hair and the scalp. It then developed the proprietary-formulation new hair-care brand KASUI and the system treatment Jalire, which uses internal hair repair to bring hair closer to a more manageable condition, and was conducting promotional activities ahead of their launch on 1 October.」

「The Company had been promoting joint research, but it ended the research at the end of March of that year after achieving certain results. Going forward, it will apply the results obtained through the joint research to aging care for hair and the scalp, as well as to the development of new functional cosmetics for life and health care to support fulfilling lives in a super-aged society.」
