It works through two mechanisms: inhibiting the enzyme tyrosinase (which is essential for melanin synthesis) and shifting the melanin production pathway from eumelanin (darker pigment) to pheomelanin (lighter pigment)
This demethylation leads to destabilization of the mRNA, resulting in reduced CHAC1 protein levels and inhibition of ferroptosis
