Thanks for all the great comments (complements). I will sort my thoughts out and post an explanation (tutorial) of this effect. In response to a comment by Opera. This is not a post effect. It's a bump/displacement map I created in PS.
It's still a work in progress though. There are a number of things to work out. i.e. Goose bumps do not appear every where. The effect is not as strong on all parts of the body, etc.

Next I'd like to tackle "peach fuzz". It's an important element for female figures and children.
Also: The redness is very slight on my monitor. I use a Mac and have a ViewSonic UltraBright A90f+ monitor. I keep everything adjusted for print, as in printing press.
