Arbutin is a tyrosinase inhibitor that blocks the compounded of dopa and dopa quinone, then it can inhibit the production of melanin. In the 1990s, arbutin was first promoted by Shisedo Cosmetics Co., Ltd. as a cosmetic whitening agent. It is another whitening agent after γ-cysteine and kojic acid. At present, the skin whitening and skin care market in developed countries has been almost monopolized by arbutin

Usually arbutin is  as a white needle-like shell or powder in the whole grass of the rhododendron plant, the leaves of the huckleberry, and many other plants

Alpha arbutin powder application & Function

Arbutin inhibits the production of melanin by inhibiting the activity of tyrosinase in the body, reduces skin pigmentation deposition, removes color spots and freckles, and has bactericidal and anti-inflammatory effects.  Arbutin helps eliminate the formation of dark and age spots and is a great natural alternative to hydroquinone for all.  Because of the possible side effects of hydroquinone, many people are looking for a safer alternative.  

Arbutin powder is used to promote lightening and evenness of skin.  Suitable for all skin types.
