Recent elucidation of regulatory mechanisms of eu- and pheomelanogenesis has led us towards an exciting new era of melanogenesis control. I will chiefly address our progress on inhibitory control of melanogenesis from the macromolecular level to human skin colour. In the past, the exploration and search for skin depigmenting agents has been focussed on and initiated from substances which can suppress isolated tyrosinase in vitro. Now, as I have classified below, many new melanogenic inhibitors have been discovered which, in spite of their non-suppressive effect on isolated naked tyrosinase, suppress melanin formation in the living pigment cell in vitro as well as in the natural world. I will also discuss a recently found unique disorder: unilateral suppression of mixed melanogenesis.
