glutathione reduces melanocyte production The critical role of redox homeostasis towards oxidation in ermanin-induced melanogenesis How do Melanocytes Make Melanin?:

In fact, the loss of FH has been previously associated with the increased production of reactive oxygen species (ROS) 9 , and the accumulation of fumarate in FH-deficient cancer cell lines leads to the formation of an adduct between fumarate and glutathione (GSH), which depletes intracellular NADPH and enhances oxidative stress 10
