Alpha-Arbutin Powder (Alpha Arbutin powder, α-Arbutin)

Alpha-Arbutin is a naturally occurring derivative of hydroquinone, found in various plants such as bearberry, blueberry, and cranberry. It is a stable form of arbutin that is known for its skin-brightening properties. Alpha-Arbutin works by inhibiting the enzyme tyrosinase, which is involved in the production of melanin, thereby reducing hyperpigmentation and promoting an even skin tone.

It is a more stable and less toxic alternative to hydroquinone in skin lightening applications. The molecule consists of a hydroquinone moiety linked to a glucose unit. It works by inhibiting the enzyme tyrosinase, which is involved in the synthesis of melanin (the pigment responsible for skin coloration). By reducing tyrosinase activity, it can prevent the formation of excessive melanin, thus having a skin lightening or depigmentation effect.

In Cosmetics: It is commonly used in facial creams, serums, lotions, and masks. The concentration of alpha-arbutin in these products can range from 0.5% to 2% depending on the formulation and the intended effect.

In Pharmaceuticals: It may be used in topical medications for the treatment of skin pigmentation disorders such as melasma and post-inflammatory hyperpigmentation.
