I don't know how this model looks but SSS will work properly on capped (solid) geometry only.

Ok
so I re-wrote the way I was doing things.  As one shader to do everything I wanted was not going to happen.
I am trying for this attempt to keep as true to the Dataset and parameters the Digital Human league have set out here:http://gl.ict.usc.edu/Research/DigitalEmily2/

So I made 4 passes  ( Difusse SSS, Single Scatter, Primary Spec, Secondary Spec)

This is only being lit up by the HDR no other lights.
I used a Max's standard Phong shader for the Spec didnt really see any other way to get around this, but the results seem to be pretty on par with theirs, even though its not completely physically plausible.  If corona has a way to turn its shader into phong that would be a great help.
I will do a Hires version later but I am very pleased with this version

I am not sure if it will help, but as the legacy Ashikhmin Shirley BRDF is not a microfacet BRDF (Anisotropic Phong?) you might try that as an alternative.
The legacy BRDF can be activated from the advanced options in the material settings by selecting the A7 legacy mode.

As I understand The Digital Human League project is trying to acheive robust physically accurate results with micro displacement/bump which is why to avoid a microfacet BRDF model.
Don't hold me to it, sure there are points that I am missing lol, but it would seem the best approach for Corona guys joining the project, it is a really interesting subject.

Actually it kinda is (-ish)

The legacy BRDF can be activated from the advanced options in the material settings and activating the A7 legacy mode.
This is no longer possible in latest daily/upcoming stable builds
Rendering is magic.

Ah, ok. I don't want to spread false information and it is good to check/confirm as I learn! Appreciate it!

I went back on this one.
To take through some post adjustment and a better composite with the background.

Plus a few close ups

here is a HDRI, with back plate Test

the interesting thing here is I used spherical enviroment HDRI, but then flatten it with ptgui- demo version.  If you know any other way to get a back plate from the spherical enviroment , please let me know
