ABSTRACT: Collagen (JC) was extracted from jellyfish ( Rhopilema esculentum ) and hydrolyzed to prepare collagen hydrolysate (JCH). The protective effects of JC and JCH against UV‐induced damages to mice skin were evaluated and compared in this article. JC and JCH could alleviate the UV‐induced abnormal changes of antioxidative indicators, including the superoxide dismutase (SOD), glutathione peroxidase (GSH‐Px), and catalase (CAT) activities and the contents of glutathione (GSH) and malondiaidehyde (MDA). JC and JCH could protect skin lipid and collagen from the UV radiation damages. Furthermore, the changes of total ceramide and glycosaminoglycan in skin were recovered significantly by JC and JCH. The action mechanisms mainly involved the antioxidative properties and the repairing to endogenous collagen synthesis of JC and JCH in vivo . JCH with the lower molecular weight showed much higher effects than JC. The results indicated that JCH was a novel antiphotoaging agent from natural resources.
