Ok, so here is what I learnt.. just to show I am actually interested in learning this stuff. OK so a blender node is used to blend two textures together and a transparency map is used to hide bits of one texture that you don't want to see. 

So as I understand it, with the transparency map I am hiding the skin parts of the texture so that what I do only effects the silk bit? 

Now I have seen how to make lips shiny but that effects the whole area. I just took the advice and I changed the node from the blender node and added a anistropic one, but again this has changed the color of the torso if you notice in the picture.
