Arbutin plant extract is both an ether and a glycoside; a glycosylated ben-zoquinone extracted from bearberry plant in the genus Arctostaphylos. It inhibits tyrosinase and thus prevents the formation of melanin. Arbutin is therefore used as a skin-lightening agent.
It is a naturally occuring derivative of hydroqui'none found in the leaves of cranberry, bearberry, and blueberry shrubs, most types of pears, and many other plants. Arbutin may inhibit melanogenesis by affecting tyrosinase activity.
