Duplicate layer (HF, LF and Background) Apply Gaussian Blur to LF Apply Image to HF Set HF to Linear Light Select LF and using the Lasso Tool select the subjects forehead. Apply Guassian Blur to the selected area. So I followed the steps above on a JPEG photo. However, the application of the blur caused the skin to go dark rather than softer. Any help would be appreciated!

You followed the steps ok, but blurring the LF layer (after it's initial blur) doesn't soften the image, but blends the colors and tones together. So you're getting more of an average of the tonal values, which appears to be darker. To soften the image you most likely want to work on the HF layer with tools that lighten the low values and darken the high values. If your intent was to blur the color and tonal values more to eliminate red spots and uneven complexion, then you need to feather your selection a lot more on the LF layer. Maybe use a low opacity brush to paint over areas of issue.
