The ferroptosis signalling pathway is comprehensive, and in addition to the classical disorders of iron metabolism, the glutathionecysteamineglutathione system and polyunsaturated fatty acid metabolism, an increasing number of signalling pathways, such as nicotinamide adenine dinucleotide phosphate/ferroptosis-inhibitory protein 1 and tetrahydrobiopterin/GPT cycloheximide 1/dihydrofolate reductase, have been identified 51
Additionally, UVB causes a significant decrease in intracellular glutathione (GSH) levels and the expression of glutathione peroxidase 4 (GPX4), which fuels photoaging and contributes to keratinocyte death through ferroptosis [20, 230,231,232]
