Skin photoaging,a phenomenon of premature skin aging due to prolonged exposure to ultraviolet(UV)radiation,manifests as wrinkles,loss of skin elasticity,pigmentation disor-ders,and age spots.Non-coding RNAs(ncRNAs),including microRNAs(miRNAs),long non-coding RNAs(lncRNAs),and circular RNAs(circRNAs),play a crucial role in regulating gene expression and the development of skin photoaging.This review summarizes the molecular mecha-nisms of specific ncRNAs(such as miR-34a,miR-134,miR-1246,lncRNA H19-miR-296-5p-IGF2,lncRNA PVT1-miR-551b-3p-AQP3,lncRNAMeg3-miR-93-5p-epiregulin,circ-COL3A1-859267 and circ-0011129)in skin photoaging.Additionally,the review discusses the potential application of ncRNA-based therapies in photoaging,as well as the current challenges and future research directions.
