You mean subsurface scattering?
Brazil had a standard skin shader, it was pretty useless. I think it would be better to add a standard SSS shader and manually tweak it to mimic skin, wax, or whatever you like. It will be implemented for sure.
The reason why other renderers offer a specialised skinshader is because you cant do reaslistic skin with a standard SSS material (unless you are going to model every layer separately).
