Cell migration assay reveals that RP can increase cell migration rate, helping to repair skin damage and restore cell viability. Immunofluorescence assay demonstrates that RP can reduce collagen degradation in skin cells by UVB radiation and reduce apoptosis of skin cells. The aim of this study is to investigate the effect of RP on UVB (Ultraviolet radiation B) induced photoaging and its potential mechanism. Retinyl palmitate (RP) is a vitamin A derivative that has been widely used in anti-aging and skin treatment. 4School of Biomedical and Pharmaceutical Sciences, Guangdong University of Technology, Guangzhou, Guangdong, China.3University of Chinese Academy of Sciences, Beijing, China.2HBN Research Institute and Biological Laboratory, Shenzhen Hujia Technology Co., Ltd., Shenzhen, Guangdong, China.1State Key Laboratory Basis of Xinjiang Indigenous Medicinal Plants Resource Utilization, CAS Key Laboratory of Chemistry of Plant Resources in Arid Regions, Xinjiang Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, Urumqi, Xing Jiang, China.Peng Shu 1,2,3 Menggeng Li 2 Nan Zhao 2 Yuan Wang 2 Lanyue Zhang 4* Zhiyun Du 1,3,4*
