Subsurface scattering material for the skin

Subsurface scattering is a Mental Ray material option to render materials like skin.
Materials light rays are not always reflected at the surface, but can also scatter under the surface and leave at another position which leads to a softer appearance, as light is blurred out over the surface. 

Old test render:
to track the difference and improvement:



Applying the new shader:

This is a test render that shows the changes in the material of the girl's skin,
The technique I used is subsurface scattering skin shader, connected it to my UV mapped texture.


Before (without SSS on the hands shader):


After (with SSS on the hands shader)


The picture below is a capture of the shader's graph network linked to the head texture:
