Product Name: alpha arbutin
alpha arbutin source: alpha-Arbutin
is a synthetic compound derived from natural plant sources. It is a
water-soluble, white powder that remains stable in a pH range between
3.5 to 6.5.
alpha arbutin introduction: Alpha-Arbutin is a pure, water soluble. biosynthetic active ingredient. AlphaArbutin blocks epidermal melanin synthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa. Arbutin appears to have fewer side effects than hydroquinone of similar concentrations - presumably due to the more gradual release. It is the more effective, faster and safer approach to promoting skin - brightening and an even skin tone on all skin types.
