Arbutin is a white powder, a hydroquinone derivative glucoside found in many plants. Like hydroquinone, it also effectively inhibits the formation of melanin and prohibits hyper-pigmentation caused by sun exposure and ultraviolet radiation.

Research on tyrosinase, the key enzyme causing melanin formation, indicates that arbutin can effectively prohibit melanin formation by blocking on the activity of tyrosinase without affecting cell proliferation. Incorporated in skin care applications, it acts as a skin-whitening agent preventing liver spots and freckles, treating sunburn, and controlling melanin production.

Arbutin is added to advanced cosmetics and sun care products whose function is lightening skin, sunscreen, and dispelling freckles. Usually, it is used in 0.5% ~ 3.0% concentrations.
