Property	Same as arbutin, alpha-arbutin can effectively inhibits formation of melanin, splash and fleck can be got ride of. Inhibitory effect on tyrosinase of alpha-arbutin is better than arbutin, and dosage of alpha-arbutin is less.
Safety property	Detailed safety data for alpha-arbutin is not obtained yet, and has being studied by us and other scientific research institutions at present.
