Alpha Arbutin Powder for Skin Whitening
Alpha-Arbutin (4- Hydroxyphenyl-±-D-glucopyranoside) is a pure, water soluble, biosynthetic active ingredient. Alpha-Arbutin blocks epidermal melanin synthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa. Arbutin appears to have fewer side effects than hydroquinone at 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. Alpha-Arbutin also minimizes liver spots and meets all the requirements of a modern skin-brightening and skin depigmentation product.
