α-Arbutin is a new type of active compound for beautifying and whiting the skin.α-Arbutin can be rapidly absorbed in the skin and selectively inhibit the activity of tyrosinase, therefore obstruct the melanogenesiswithout altering the normal growth of the epidermic cell or inhibiting the expression of tyrosinase itself. Meanwhile, α-Arbutin also promotes decomposition and excretion of melanin, therefore, reduces the deposition of skin pigment and removes color spots and freckles. α-Arbutin's inhibition toward mammalian tyrosinase is 10 times more active than β-Arbutin and the involved processes neither produce hydroquinone, nor have other side effects including toxicity, irritation and sensitization of the skin. These properties result in α-Arbutin being the safest and most effective skin-whitening and spot-removing substance developd to date. α-Arbutin also helps disinfect and moisturize the skin and eliminate inflammation. It helps the wounded skin recover as well. These properties make α-Arbutin an essential cosmetic ingredient for many applications.
