The road to crafting a top notch skin shader is hard. For a long time, I tried with Poser 12 not to make the characters look like mannequins, with shiny skin like a sweaty sumo. On male and older female characters, it's easier to trick with bump and normal maps. The skin may be blotchy and more wrinkled. With young people (and those young at heart?) it is difficult to get a grip on this waxy, slightly translucent surface.
