PF ameliorates H₂O₂-induced apoptosis in melanocytes. Melanocytes were treated with PF for 24 h (A) or 48h (B) and then treated with H₂O₂ for another 24 h. The cell apoptosis was analyzed by the flow cytometry and each figure shown was representative image from three independent experiments, the percentages of cells apoptosis were shown as the right bar graphs and the data were presented as the mean ± standard deviation across three independent experiments. ***P < 0.001. ns, not significant; H₂O₂, hydrogen peroxide; PF, Paeoniflorin; h, hours; M, mol/L.
