Suppressing Specularity on Face

[Shawshank]

Hmmmm. I think you're going to be a bit stuck. As soon as the image has blown out - i.e. too much specularity on the face - you cant fix it. The pixels have gone to white and you've lost the information on the skin tone, shape etc. The only way to really fix this is to reshoot with lights that are dimmer/further away from your model. If that isn't possible i'd suggest playing around with the levels... But its not really going to help much.

EDIT: sorry just re-read your post. I have a better idea of what you're trying to achieve now. I would suggest the following: (There's no one-click solution to this problem but here's a quick work-around)

*select a large area of 'clean' skin that's not too dark.
*Copy it onto a new layer (ctrl J/ Apple J)
*bring it over the top of your specularity area.
*click the layer mask button (down the bottom of layers palette)
*invert the mask (ctrl i)
*with a white soft edged brush paint to reveal the 'clean' skin
*adjust the levels & saturation to blend the skin into surrounding areas.

Thanks for the tip! That worked every well. I don't have too much specularity on the face which is good. I just wanted to get rid of the remaining small areas so I can let my specular map do the work in Maya. Thanks again for the help!

sometimes to get only grayscale details/remove small hue variations I use the 'High Pass' filter combined with hue http://library.creativecow.net/articles/polevoy_george/texture_tiling.php but it might not work for lightness
