Ultraviolet is the one of the main environmental factors promoting aging process via increased intracellular generation of reactive oxygen species (ROS) and decreased expression of endogenous antioxidant enzymes and molecules. Therefore, in this study, we tried to search for natural skin-protective antioxidant materials from marine origins (Porphyra Thalli, Laminariae japonicae thallus, Ostreae Concha, Sargassum Thallus, Undaria thallus, Haliotidis Concha, Codium thalli, Syngnathoides biaculeatus, Hippocampus, Stichopus Stichopus, Thalli, Hizikia fusiforme thalli) which exhibit free radical scavenging activity and protect against UVB-induced cytotoxicity and oxidative cell death. Free radical scavenging activity was shown in order of Undaria thallus. Sargassum Thallus, Laminariae japonicae thallus, Hippocampus, Haliotidis Concha, Ostreae Concha, Syngnathoides biacuJeatus. In another experiment, UVB-induced cytotoxicity and cell death were effectively suppressed by treatment of Sargassum Thallus, Haliotidis Concha, Codium thalli, or Hippocampus water extract. Furthermore, UVB-induced cell death was mediated by intracellular accumulation or ROS, which was significantly inhibited by treatment with aforementioned extracts. The protective effect of these marine natural products seemed to be mediated by increased expression of antioxidant enzymes such as catalase, superoxide dismutase, and heme oxygenase-1. These results suggest that Sargassum Thallus, Haliotidis Concha, Codium thalli, and Hippocampus may have preventive and protective potentials as new functional cosmetics against oxidative stress-mediated skin damages and aging with antioxidant properties.
