GAE-mediated inhibition of melanogenesis induced by SCF in normal human epidermal melanocytes. Reconstructed epidermis were cultured with GAE and SCF (20 nM) for 14 days. Images were exhibited using a microscope a. L-values of cell pigmentation were measured using a chromameter (CR-300, Minolta) b. Data are mean ± standard deviation. ##p < 0.01 compared with the vehicle-treated group, **p < 0.01 compared with the SCF-treated group (n = 3)
