Use of  Alpha-Arbutin 

Whitening material of Cosmetics.

Alpha-arbutin is a pure, water-soluble active ingredient that promotes skin whitening and applies to any skin. Alpha-arbutin inhibits the formation of epidermal melanin by blocking the oxidation of tyrosinase and dopa. The whitening effect is faster and more effective than the existing single component on the blemishes and the skin damage after UV irradiation Has a higher stability and efficacy.

Alpha arbutin inhibits tyrosinase activity at very low concentrations. Although the inhibitory mechanism is different from arbutin, it is almost 10 times more intense than arbutin and at higher concentrations Cell growth also has no effect. In 2002, α-arbutin has been abroad as a safe and effective skin lightening active agent to the cosmetics market. Alpha-arbutin can make the skin look more beautiful and rich, it has a marked effect on the UV scald marks, its chemical properties more stable than β-arbutin, can be more easily add a variety of whitening Skin cosmetics.
