Dark spots form when melanin production becomes uneven or excessive in certain areas (a process called hyperpigmentation)

[72] reported that ferroptosis occurs in a mouse model of APAP-induced acute liver failure, showing elevated lipid peroxides derived from n -6 PUFAs

biochemically, there is intracellular glutathione (GSH) depletion and decreased activity of glutathione peroxidase 4 (GPX4), lipid peroxides cannot be metabolized by the GPX4-catalyzed reduction reaction, and Fe 2+ oxidizes lipids in a Fenton-like manner, resulting in a large amount of ROS, which promotes ferroptosis 3,6
