I would suggest to reduce the bump value for the lips. On the "SkinModifier" panel in SkinVue8 under bump values is a pull down menu. Select Lips and enter a lower value. The default value seems to be a bit high in most cases.

You will have to adjust these according to your taste, the bump maps that come with your texture and the lighting as well as depending on the distance to camera.
The modifier panels are very powerful and give you a great deal of control over the skin look.
