I agree. First of all, strictly speaking while they are both Adobe products, Lightroom is not actually Photoshop; it's a stand-alone application which incorporates Adobe Camera Raw (with many enhancements), a module also shared by Photoshop. The main advantages to Lightroom are that it does non-destructive editing (the edit's aren't applied to the image, but saved in a file and applied on export) and that it allows for selective enhancements.That said, My suggestion would be to open the original file in Lightroom and use the selective enhancement brush with an exposure adjustment to reduce the brightness of the background, and then do a second adjustment to increase (carefully and gently - increasing exposure increases digital noise) the exposure on the face.
