Echinacoside Alleviates UVB Irradiation-Mediated Skin Damage via Inhibition of Oxidative Stress, DNA Damage, and Apoptosis

Figure 6

Echinacoside suppressed intracellular ROS generation. (a) Cells were pretreated with echinacoside (25, 50, and 100 μM) before exposure to UVB (300 mJ/cm²) irradiation. And 24 h later with UVB irradiation, DCFHDA (10 μM) was introduced into the cells, and fluorescence was measured by flow cytometry. (b) DCFH-DA fluorescence was measured by confocal microscopy. Data are presented as means ± SD (). ^## versus control group, versus UVB group.
