Reaction stages when a psoralen molecule binds to DNA. The result is that the psoralen is permanently bound to the DNA via a cyclobutane ring. The cell is altered and thus damaged, and triggers the process of programmed cell death. Credit: ACS/Janina Diekmann More The term “PUVA’ stands for ‘psoralen’ and ‘UV-A radiation.’ Psoralens are
