It's not quite as simple as that, that would only give you a soft-glow effect.
You'd either have to manually use the "Blur Tool" (looks like a drop of water on the Photoshop toolbar) and blur the parts of the face. Or, you could select the areas of the face that you want to be blurred using the lasso tool set at feathering at maybe 15 px, and then do Filter --> Blur --> Gaussian Blur, maybe 5.0 pixels.
