I played around with the subsurface scatterer DT3DskinShader from miguel santiago. his very cool site can be found at www.digiteck3d.com the shader is awsome and for me the first time I use SSS. the skin I tried to create does not look very natural by now (too much wet spec maybe) because the interface contains of over 50 tweakers and as you guessed - it takes time to find out what everyone of it does (dokumentation is included). I post a shot from the topView. have fun!
