Indeed!  I know a few ladies who could 'Drink Men or aliens under the table... ;-)
Well, for one thing, the ingredients used in those 'Alien spirits' are for the
most part "indigenous" to their planets.  So, human anatomy is not used
to absorbing them.  Which could account for the "Stronger effect"

Ah!  The Blue hue of the skin is simply a filter in C4D, you could accomplish
the same effect in Poser.  You first need to desaturate the texture you want
to use, then simply multiply it by whatever hue you which...

So, no need for complicated nodes here.  You just need to find the proper
rgb colors to multiply your Greyscale texture.   Also, i use a bit of 'Translucence'
on the skin(very low setting).  I would plug that node to the Greyscale map also.

Do not forget that your light setup will affect the final look of your skin.
I never have more then 3 lites in any scene.  2 have shadows, the third is
just a 'Fill Light'...

Hope this info helps you!
