Arbutin is a glucosulated hydroquinone, extracted from the bearberry plant. Hydroquinone has been
commercially available since the 1960s as an agent in skin lightening products.1 Arbutin is naturally found
in wheat, pear skins, and the leaves of blueberries and cranberries, and it is metabolized by the body to
produce hydroquinone with most of the product excreted in urine. Topical application of arbutin inhibits the
production of melanin with minimal systemic absorption.
