So, nice soft dry human skin has this 'glow' to it that LuxRender (and LuxCore and Reality, both being based on LuxRender) do really well, and even Iray is pretty good at it, which is good, especially if you are rendering nice soft dry human skin. It's more than just specular shine or sub-surface scattering, it has to do with how the top several layers of skin reflect and spread light between them... and it's just so pretty.
The thing is, it's tough to get it looking good in Cycles, for reasons I don't understand (but believe me I've tried). I've given up trying to build a real-world (energy conserving) shader network that duplicates the effect in Cycles, I just can't get it... I'm not smart enough. On the other hand, I can cheat with the best of them.
This node network is based on the Red as Sin shader network, with an Add Shader Node layering a soft glow of extra shine on the parts the light hits most directly. It works pretty well, good enough that I figured I'd share it here.
