Help with pale skin with PBR Skin Shader

evacyn

I'm trying to convert some of my characters with pale skin to the PBR Skin Shader and I can't even get close to how it looks in Iray. It seems like the Transluency Color just makes everyone look tanned or flat, and the closest I can get to the original skin requires me adding some pale blue to the Base Color. 

Does anyone have any good resources (video, guides) on using the PBR shader or even how to make the skins look more like the original source Iray shader settings.

Thanks!
