Beta arbutin powder is the active substance originated from natural plant which can whiten and lighten skin. Beta arbutin powder can infiltrate into the skin quickly without affecting the concentration of cell multiplication and effectively prevent activity of tyrosinase in the skin and the forming of melanin. By combined arbutin with tyrosinase, decomposition and drainage of melanin are accelerated, splash and fleck can be got ride of and no side effects are caused. Beta arbutin powder is one of the safest and most efficient whitening materials that are popular at present. Beta arbutin powder is also the most competitive whitening activity in the 21st century.

Arbutin effectively inhibits formation of melanin, splash and fleck can be got ride of and no side effects are caused. Arbutin can also moisten the skin which looks very lightening, so arbutin is used skin lightening and whitening agents in the cosmetics. Arbutin was also used as a drug.

Description:
Arbutin is a glycosylated hydroquinone extracted from bearberry plant. Arbutin acts as an inhibitor of tyrosinase, and is used as a skin-lightening agent for the prevention of melanin formation in skin conditions. It is a good functional cosmetics material.
