The bearberry extract is extracted from the dried leaves of the rhododendron plant bearberry, and the main active components are arbutin and ursolic acid. Ursolic acid not only has resistance to a variety of carcinogenic and cancer-promoting substances, but also inhibits the growth of various malignant tumor cells. Arbutin is an inhibitor of tyrosinase in human melanocytes. Arbutin can effectively inhibit the activity of biological tyrosinase in the skin, block the formation of melanin, and directly combine with tyrosinase by itself. , Accelerates the decomposition and excretion of melanin, thereby reducing skin pigmentation, removing pigmentation and freckles.
