Mechanism of action

Eflornithine is an irreversible inhibitor of ornithine decarboxylase (ODC), the rate-limiting enzyme in polyamine biosynthesis. Polyamines are essential for cell proliferation and differentiation, including in hair follicles. By depleting polyamines in hair follicle cells, eflornithine reduces the rate of hair growth and can decrease hair density and thickness in unwanted facial hair.
