Introductions
Our product alpha-Arbutin is made from bioconversion with single alpha configuration, and the purity is more than 99.5%. It can quickly penetrate into skin and inhibit the activity of tyrosinase effectively without affecting the concentration of skin cell proliferation at the same time. Alpha-arbutin blocks formation of melanin by combining with tyrosinase, which finally leads to accelerate the melanin's decomposition and discharge, thus reduces the skin pigment deposition and removes spots and freckles. As one of the most safe and effective whitening ingredients, Alpha-arbutin is very popular in foreign countries and also the most competitive skin whitening spot surfactant in the 21st century.
Arbutin can be divided into two types according to the different structures: Alpha-arbutin and beta-arbutin. Both of them can achieve the affection of skin lighting by inhibiting the activity of tyrosinase. However, relevant studies show that after smearing on the skin, beta-arbutin can explode hydroquinone which is suspected to be carcinogenic.
Beta-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.
