Arbutin

What is it?

Arbutin is a naturally occurring glycoside (a glycosylated form of hydroquinone), most often derived from bearberry and related plants, used in skincare as a tyrosinase-inhibiting brightening ingredient.

What does it do?

Comparative laboratory studies found arbutin inhibits human tyrosinase, but relatively weakly -- with a half-maximal inhibitory concentration in the millimolar range -- making it markedly less potent in vitro than newer agents like 4-n-butylresorcinol, though it remains a widely used, gentler option in brightening formulations.
