There are two distrinct types of sss - 1) lighting coming from the back of the object (relative to the camera) and coming out the front (basically a form of translucence), and 2) lighting coming from the front of the object (relative to the camera) and bouncing back to the camera from somewhere else on the surface (see above example). For example, human skin can be make mroe realistic with sss (both front and back facing). See attached link for how to fake front-facing sss.
