OK, here are my tests what I did was follow a tutorial offered by face_off (creator of the real skin shading product), when I started I convinced myself of not to just copy the steps but go slow and understand what I was doing to be able to adapt the shading to my needs, the most complex part of the tutorial (and the most important) is the subsurface scatering (sss), to achieve this face_off uses some complex formulas based on the position of the main light  in the scene and this do allmost necesary the use of his product    , so I decided to try to achieve it by myself in the most easy way, maybe the efect is not that perfect and I think it can be improved a little more but I am happy with it.

Beautiful work.
