Arbutin is the active substance originated from natural plant which can whiten and lighten skin.
It 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.
It is one of the safest and most efficient whitening materials that are popular at present.
It is also the most competitive whitening activity in the 21st century.
