Uva Ursi Leaf Extract /Arbutin
Glucosylatedhydroquinone, derived from the leaves of fruits such as bearberry, pear and cranberry. See Alpha Arbutin.
A natural skin lightening/whitening agent. It works by slowly releasing hydroquinone through hydrolysis, which in turn blocks Tyrosinase activity and reduces the skin’s melanin (pigmentation) production. In cosmetics, this ingredient appears in two different forms: Alpha-Arbutin or Beta-Arbutin. Due to patenting concerns, most skin care products contain plant extracts that contain Arbutin (e.g. bearberry, pear, blueberry), rather than pure Arbutin. Used in a variety of cosmetics, particularly ones aimed at lightening the skin such as lotions, crèmes, serums, cleansers, and spot treatments.
