Graphical representation of the LineweaverBurk equation showing the inhibition of the diphenolase activity of tyrosinase in the presence of -arbutin 3 mM. Alpha-Arbutin is a glycosylated hydroquinone that was first discovered in bearberry (Arctostapylos uva-ursi) and then in the leaves of lingonberry, Chinese pear, creeping saxifrage, strawberry tree, marjoram, evergreen. The enzyme catalyzes two types of reaction: (a) the ortho-hydroxylation of monophenols, rendering into o-diphenols (monophenolase activity), and (b) the oxidation of o-diphenols to o-quinones (diphenolase activity). You should apply sunscreen on top of it because it can make you more sensitive to the sun. This is dangerous since you never known how heating another product with arbutin changes the chemical composition. Structurally it is an -glicoside. This quantity is given by the equation R = [D]ss / [M]ss [41,43], where [D]ss and [M]ss are the concentrations of o-diphenol and monophenol respectively in the steady state with [M]ss [M]0.
