Alpha-arbutin is the most purified form of arbutin, a glucoside derived from hydroquinone naturally present in the leaves of bearberry, blueberry, and cranberry. It is recognized in scientific literature as one of the most studied forms among actives associated with complexion evenness in cosmetics. Available data link alpha-arbutin to regulation of melanogenesis via its documented action on tyrosinase, an enzyme involved in melanin synthesis. Its profile is documented as more studied than beta-arbutin on this mechanism. It is associated, according to available scientific data, with a selective action on hyperactive melanocytes involved in the appearance of pigmentation irregularities, without affecting the skin's natural pigmentation, making it suitable for all phototypes. Clinical studies report visible reduction of pigmentation irregularities and improvement in the appearance of complexion evenness after several weeks of regular use, with a documented good tolerance profile.
In summary, a well-studied active ingredient associated with visible reduction of pigmentation irregularities and visible complexion evenness.
