The influence of the peptide VY-9 on B16F10 melanoma cell cytotoxicity (a), tyrosinase activity (b), and melanin content (c). The positive control used was arbutin (0.2 mM). The findings are presented in the form of percentage of the control, while the values represent the mean ± SD from three independent replications. For Duncan’s test, the different letters are used to denote a significant statistical difference between groups when p < 0.05.
