I get that glossiness in some textures at times.  The first thing to do is to be sure you have the bump maps on, a little irregularity always helps.  But, the real trick here is to select all of the skin areas (the ones you don't want shiny, that is) and scroll all the way down to the bottom of the surfaces tab.  Change the "lighting model" to "Skin"  (the default is "Plastic").

I find that clears it right up.
