Many thanks for links and for your nice words, THX1138. In fact I've already knew Steven Stahlberg's tutorial, and I tried to apply his method for my model before, but I wasn't able to get proper results. Because that I start searching on Maya's documentation a way to use MR. I think it was better this way, now I have some knowledge in MR, PFX, Maya render...
SSS is a relatively easy shader to use, I read an excelent tutorial yesterday (on www.highend3d.com) and learn all the basic things I have to know by now.

Since some people here are posting their rig systems, here goes mine. First, we have Michelle's skeleton. She's controled by a mix of IK and FX, and much patience...

Here is the real skin of Michelle, some poly surfaces that act as wrap deformers. I still have to do one for control hair.

And here some blendshapes to help us with bad deformations. If time wasn't a problem, I should have done much more.
