Where’s the Corrugator Supercilii muscle located?

It’s located in the forehead between each eyebrow. It sits between part of the Occipitofrontalis and the Orbicularis Oculi muscles (to which it blends it’s fibers partially). It starts in the bone at the supraciliary arch and it’s fibers travel laterally and upwards to the supraorbital margin, and hook into the skin to play a role in traction of that part of skin. This explains the actions of the muscle, pulling the eyebrows downward and to the center (medially).
