use a reflector
This is the same technique as loop lighting, but the light source is usually set up at that 45 degree angle from the subject. You move the light further to the side of the subject until the opposite side of the face (the side in the shadows) has a small triangle of light on the cheek just below the eye. You should also set the height of the light a foot or two above eye level. If you’re using a single light source, you can use a reflector to create this lighting setup.
