Allicin inhibits intracellular ROS generation and oxidative stress in UVB-induced keratinocytes. A HaCaT cells were stained with DCFH-DA, and the representative images were shown (200 ×). B Quantitative analysis of the relative DCFH-DA fluorescence intensity of HaCaT cells. The cell lysate of HaCaT cells was used to measure the oxidative stress markers for C MDA, D SOD, E CAT and F GSH-Px. Data are presented as mean ± SD in triplicates and analyzed using one-way ANOVA, and LSD was used for the post-hoc test. Scale 50 µm. ***P < 0.001 vs. control group; ###P < 0.001 vs. UVB group
