How to remove shinny face in photos?

I have a client who was sweating something awful in his photos and they want to me to remove the shine.  How can this be done in Photoshop or Lightroom.  

Thank you!

Photoshop, frequency separation, and a lot of work.

I have portrait pro for just that king of issue. It is far quicker than a general editing system like PS. 

In such case, every solution is easier prior to SR than any work in
post-production.

This is a frequent problem in this season but there is no other way.

Shiny areas on a subject’s face which are caused by a flash reflecting off a shiny surface or by uneven lighting. It tends to make the subject look as if they are sweating, which is not a good look. 
1. Open up the photograph with the shiny hot spots that you want to fix.
2. Select the Clone Stamp Tool (S) from the toolbox. In the Options Bar at the top of the screen, choose a large, soft-edged brush and set the Mode to Darken and lower the Opacity to about 50%.
The idea behind setting the mode to Darken is that the only pixels that will change are the ones that are lighter than our sample area. The hot spots are essentially light-colored pixels.
3. On your subject’s face, choose an area of “clean” or non-hot spot skin. This will be the reference point and Photoshop will now only change pixels that are lighter than this. Hold down the Alt (Windows) or Option (Mac) key and click to set the reference point. The cursor will change to an eye-dropper.
4. Start to paint over the hot spots with the Clone Stamp tool. The hot spots will fade but it will still look like natural skin. You’ll find that you need to resample several times in order to correctly match the skin tones. Just Alt/Option-click every time you want to resample and start to paint again.
If the effect is too much, you can also reduce down the Opacity of the Clone Stamp Tool a little further to about 45 – 40%. Be especially careful on the skin under the eyes. You don’t want to replace hot spots with dark bags! Workaround your image until you’ve removed all of the hot spots.
So with a couple of seconds of retouching with the Clone Stamp Tool and the right blending mode you can quickly and easily do a makeover and remove the sweaty, shiny look.
Hope It Will Hwlp You.......

Make sure to do this on a duplicate layer so you can adjust opacity later if needed. Also pick from an area near the same tone and lightness as you want the repaired skin to be.
