Fortunately, the spots can be retouched in Photoshop relatively easily. Techwalla has a post that breaks out the steps required for three different techniques. I'm going to engage in some cut and paste of the method I used on the sample image included in this post after looking at the before and after images.

Step by Step Technique
I used the steps outlined on Techwalla. Below is my abstract of their steps (I am embedding it here, in case the Techwalla link changes).
- Open image in Photoshop
- Create a new, blank layer by clicking the Create a New Layer icon in the Layers panel on bottom right of Photoshop UI
- Select the Brush tool -- keyboard shortcut B -- and then select Window and Brush -- keyboard shortcut F5 -- from the main menu to open the Brush panel.
- Choose Smoothing and a Soft Round Brush from the Brush panel. Close the panel. The size of the brush can be adjusted as needed.
- Set Opacity and Flow. Setting the opacity at 20% - 40% and the flow around 50% is a good starting place. You will likely need to adjust this throughout the editing process.
- With the Brush tool selected, hold the Alt key and left-click on an area of the picture near the shiny area you want to correct. Choose a non-shiny area where the skin tone looks the way you want.
- Paint with the brush on the area you want to correct. Re-select skin tone as you move to a new area of shine. Adjust the size of the brush, Opacity and Flow as necessary.
- When you are happy with the results, select Layer and then Merge Visible to merge the layers. Select the Spot Healing Brush Tool -- keyboard shortcut J -- and carefully remove any distracting imperfections. Size your brush a little larger than the spot you want to heal and select Content-Aware as the Type. Left-click the spot to heal it. Repeat as necessary.
