Ok, I've got a bit of a problem that apparently isn't going to be as easy a fix as I'd hoped.

Keep in mind I know nothing about how to use SSS beyond the vague descriptions I've read in the reference manual, and the demo thread about SSS on human figures over at RDNA.  Nevertheless, I would really like to learn how to take advantage of it.

I'm working on my first scene with SSS, using the Dublin character for V4, which comes with SSS shaders.  Trouble is, her skin looks too transluscent, and I need to know how to dial down the translucency.  Below is a shot of her face, and the shader nodes that came with the SkinHead.

The scene is indoors, namely the Dream Home Kitchen by DAZ Studio.  The lighting is my own setup, using a 4-point system with a Key, Back, and two Fill lights, and IDL.  GC is enabled in render settings with all props and figures set to 1 via the MaterialMods script.
