Protective effects of HFPS against UVB-induced HDF cell damage: (A) protective effects of HFPS against UVB-induced HDF cell damage; and (B) intracellular ROS scavenging effect of HFPS in UVB-irradiated HDF cells. Cell viability was measured by MTT assay and intracellular ROS level was measured by DCF-DA assay. The data are expressed as the means ± SE (n = 3). * p < 0.05, ** p < 0.01 as compared to UVB-exposed group and ## p < 0.01 as compared to control group.
