Natural Alpha Arbutin Powder 99.5% of Blueberries Extract for Skin Lightening

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.
