Spectrophotometric recordings of the effect of different concentrations of -arbutin on the diphenolase activity of tyrosinase, using L-dopa as substrate. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. The stability of the MBTH-quinone adducts and the rapidity of the kinetic assays makes this a suitable method for determining the monophenolase and diphenolase activities of tyrosinase [40,41,44,45] (S1A Fig).
