Protective effects of a novel FS-Collagen hydrolysates against UV- and d-galactose-induced skin aging

Abstract

AbstractThe oral consumption of collagen hydrolysates derived from various animal tissues has been demonstrated to have beneficial effects on skin health, particularly in combating the signs of aging. Here in this study, a novel animal-derived FS-Collagen hydrolysates were developed and its effects against skin aging was analyzed in a new mice skin aging model established through a combination of UV irradiation and d-galactose induction. 8 Weeks of oral FS-Collagen administration demonstrated significant protective effects against skin aging in mice, evidenced by the preservation of the skin’s macroscopic appearance, the restoration of skin composition and structure, an enhancement in antioxidant capacity and the inhibition of inflammation. Additionally, FS-Collagen safeguards skin barrier integrity and cellular connections, particularly by maintaining the expression levels of Dsg1 and Jam-A. In summary, the FS-Collagen exhibits positive effects in countering skin aging and holds promise as an alternative functional nutrition supplement for anti-skin aging care.
