This study investigated the cosmetic effects of enzymatic hydrolytes of an aquatic by-product, fish skin. The skins of olive flounder Paralichthys olivaceus (PO) and Alaska pollock Gadus chalcogrammus (AP) were hydrolyzed using pepsin, Alcalase, and Protemax. Three enzymatic hydrolytes were obtained and the inhibitory effects of these hydrolytes on the aging-related enzymes tyrosinase, elastase, and collagenase were determined. The results indicated that the pepsin hydrolytes of PO and PA had stronger activities than the other hydrolytes. PO and PA also significantly reduced the intracellular reactive oxygen species levels in and improved the viability of H₂O₂-treated Vero cells; decreased nitric oxide production by and increased the cell viability of lipopolysaccharide-treated RAW 264.7 cells; and reduced intracellular reactive oxygen species levels and improved the viability of ultraviolet B irradiated HaCaT cells and human dermal fibroblasts. Furthermore, PO and PA remarkably reduced the intra- and extracellular melanin contents of alpha-melanocyte-stimulating hormone-stimulated B16F10 cells. These results demonstrate that PO and PA have potential for use in the cosmetic industry.
