SSS-based method with Nodes

This method will use material nodes and SSS (SubSurfaceScattering) to create a more realistic slightly tanned caucasian skin.

Nodes

Just enable it as a Nodes material and create two material nodes, referring the first as Node1 and the second as Node2. Skip this section if you are not a "noob".
First off, under the "Materials" section select {Add new} and under "Links and Pipeline" tab select "Nodes".Now go to the "Window Type", click, it and from the drop-down menu select "Node Editor". You should have a Node marked as Out and another as Material.Right-click on an empty space and select Add>Input>Material. Link the top-right {Color} (yellow circle), from the node you've created and link it to the bottom-left {Color} of the other Material node. Click on {Add new} in each Material node.

Node1

Select Node1

(Note: you can change the IOR to give a lighter,+, or darker,-, skin)
Front:1.15
Back:1
Go to the color picker (not Col slider), Hex:E9B08F

Node2

Select Node2

On the "Materials button"
