The rest of the experimental conditions were [E]0 = 80 nM and [L-dopa]0 = 0.5 mM. In vitro studies of human melanocytes exposed to arbutin at concentrations below 300 g/mL reported decreased tyrosinase activity and melanin content with little evidence of cytotoxicity. Subsequently, the same authors show that -arbutin does not inhibit the growth of cultured human melanoma cells, HMV-II, but it does inhibit melanin synthesis, meaning that the use -arbutin in cosmetics is effective and safe for treating hyperpigmentation disorders [30]. $20.00 (10% off) -Arbutin is produced by chemical synthesis.
