I think the skin shader setup is a little complicated, and there are some nodes that are not much needed.
Here’s a very basic setup (i think it’s fair enuogh though) which i use mostly. You may want to notice the sss scale which is far below yours. The best way to find the good solution is to play a little with a cube or a sphere in a dark environment with a simple light. The key is that tweaking values should go by little steps. Another hint: to figure out what color the scaterring effect will be, is to simply copy an rgb setup from any color wheel (eg. for a red scattering - r:1 g:0 b:0 etc.).
And you can also try bump instead of a displacement effect.
oops, the glossy went red, sorry for that its white or little bluish…
