When you get that glare on a person's face, it's really only part of the face that reflects the light back to the camera. The girl on the bottom right, for example, the light on her forehead moves when she changes her pose. In the first pic on the left, the light is square on with her forehead, and then only on her left cheek (our right). When she tilts her head in the next pic, the light on her forehead moves, and now you've got the glare on both cheeks. Compare that to the woman next to her, virtually no glare there. It's all about the reflective quality of her facial skin.
People use different methods to clean that up. I'm not familiar with PSE, but what I would do is create a second layer. I would clone the skin from other parts of the forehead onto the second layer, and then when I was done and happy with my cloning, I would reduce the opacity until I felt it looks natural. I rarely reduce it less than 80% on a job like this.
As for feathering, instead of pointing the main light directly at the subject, you'd point it slightly in front of her so she's get a feathered version of the light instead of the full intense light. You may need to adjust the light settings or your camera settings, but this will reduce some of the reflection.
