Alpha-Arbutin is a pure, water-soluble, biosynthetic active ingredient in powder form that promotes lightening and even skin tone on all skin types. It is the epimer of arbutin, which has been found to have stronger inhibitory action than that of arbutin, Even in very low concentration, a-arbutin can inhibit the activity of tyrosinase. Alpha Arbutin's inhibitory mechanism is different from that of arbutin and its intensity is 10 times as much as that of arbutin. The a-glucosidic bond in alpha Arbutin offers higher stability and efficancy than the B form in the related Beta-Arbutin. This leads to a skin lightening active that acts faster and more efficiently than existing single components, minimizes liver spots and reduces the degree of skin tanning after UV exposure. A skin lightening study on 80 Chinese women showed that an emulsion containing 1% Alpha-Arbutin results in a faster and more pronounced skin lightening effect after 1 month when compared with other commonly used mono-substances at 1% ea.
