Sometimes this is caused by the light setup, sometimes it's caused by the texture.  If you want to make the skin look a little shinier, just go into the material room/lab and increase the specular color value a teensy bit.  Don't forget to write down the new value when you find one you like and apply it to all the material zones you want affected.
