Effects of l‐AHG on cell viability in various melanin‐producing cells. (A) The chemical structures of 3,6‐anhydro‐l‐galactose (l‐AHG). Effects of l‐AHG on cell viability in various melanocytes, including HEMs (B), melan‐a cells (C), and B16F10 cells (D). Cell viability was measured by the MTT assay as described in the Materials and Methods. The results are expressed as the relative percentage of the untreated group. All data (n = 3) represent the mean values ± SD. Means with letters (a‐c) in a graph are significantly different from each other at P < .05. HEMs, human epidermal melanocytes; SD, standard deviation
