Cell viability changes induced in HDF (A, C) and melanocytes (B, D) exposed to artificial blue light and EDA pre-treatment. Cells were incubated with EDA 0.1 mg/mL for 24 h and then irradiated at the indicated doses. Cell viability was evaluated by MTT assay performed 24 h after irradiation (n ≥ 3). Data were expressed as % of control cells. Data are shown as mean ± standard error of the mean (SEM). ### p < 0.001 vs control cells and * p < 0.05 vs the corresponding irradiated (Irr) cells. Scale bar: 50 µm.
