@ ChromeStar You noted correctly and I made a point to mention that the scaling and radius value had a direct correlation with each other, the higher the scaling, the lower each RBG radius should be to maintain some measure of acceptable SSS without causing major blooming in unexpected areas.  It struck me odd that the values published from the original scientific paper were 100 times higher than the ones mentioned in the Poser manual.  Just the same, if you strike a balance between Subsurface and Subsurface Radius then you shouldn't need to be overconcerned about the glow effect because it won't occur under most conditions.

Now, those self-collision graying that you sometimes see at joint bends may be an occlusion issue rather than SSS.  I found myself with a similar issue in a render I was working on, the lighting was perfect but the elbow bend lacked the shadowing that I was expecting.  I had to introduce an Ambient Occlusion node into the skin material shader to solve that problem but it was frustrating trying to track down the solution.
