Paint With Light II helps bring out detail without burning like PWL I. I did not post an action but all you do is make a Ctrl+Shift+N/Softlight mode and "fill with grey". Paint with black or white brush.

If you read the beginning of the above post, notice that PWLII was orginally used to fix Lens Flare on this picture.
