Zenex Organic Arbutin/β Arbutin/α Arbutin Powder Powder Pack of 100 Gram

Arbutin, chemical name 4-hydroxyphenyl-D-glucopyranoside, it is an ingredient extracted from the Bearberryleaves of the BearberryBRhododendron family plant Ursolin. It can inhibit the activity of tyrosinase in the body, prevent the generation of melanin, reduce skin pigment deposition, remove pigmentation and freckles, and also have bactericidal and anti-inflammatory effects. It is mainly used in cosmetics.

The main factor determining the depth of skin color is the content and distribution of melanin in the skin, which is produced within the melanocytes in the basal layer of the skin epidermis. The initial raw material for melanin formation, tyrosine, undergoes a series of complex biochemical reactions under the action of tyrosinase, ultimately forming melanin. It transfers from the basal layer to the outer layer of the epidermis through synapses, coloring the skin and forming pigmentation spots.

In the process of melanin formation, as the main rate limiting enzyme, the activity of tyrosinase determines the amount of melanin formation. Tyrosinase has tyrosine hydroxylase activity (catalyzing tyrosine → dopa) and dopa oxidase activity (catalyzing dopa → dopaquinone), and is a key factor in the synthesis of melanin by melanocytes.
