Protective Effects of a Mixture of Propolis and Petasites japonicus Against UVB-Induced Photoaging Through Suppression of Oxidative Stress and MAPK/AP-1 Signaling
Ultraviolet B (UVB)-induced photoaging is associated with oxidative stress, inflammation, and extracellular matrix (ECM) degradation. This study investigated the protective effects of a mixture of propolis and Petasites japonicus (PPJM) against UVB-induced photoaging in SKH-1 hairless mice. HPLC analysis identified bak...
