EXACTLY !!!
Like Hawk, I can guarantee you that something like 90% of the effect was due to good, carefully thought-out and well-controlled studio lighting, with only a small fraction of the effect done in PP.
The photographer positioned a couple of studio strobes well in back of the subject to give the near rim-light effect. He then used a lighting modifier (probably a snoot, not a grid) on the strobe(s), and then used flags to further prevent inadvertent light spill. In addition, the shot was probably taken in a studio painted entirely black, or with black drapes to further soak up accidental spill light. Also, suitable makeup was used to control the nearly grazing incidence reflections from the subject's skin.
It really isn't that complicated to set up a shot like this -- one just has to be methodical.
