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.
Arbutin synthesized by our company owns high purity and
excellent quality. Almost no hydroquinone can be
examined. It is the only arbutin product that can meet
this high standard.
