post processing - How do you make a skin tone metallic brown?

First of, i'd like to say that i'm partially colour blind which makes this task more difficult for me. I'm wondering if it is possible to change a person's skin tone in photoshop from something pretty common to look (in terms of color and contrast) like the image below:

Do you think this is done by using some light modifiers and then just a touch of post-processing? Or could i just take some relatively pale skin and do the same just in photoshop?

I've noticed that a similar thing happens when you raise the blacks in curves and then lower some dark colours to create some contrast. It creates a beautiful effect in terms of contrast, but the colour is still off.

Here's another example of a more usual skin tone:

Would it be possible to match skin tones in terms of color and contrast in the image 2 to look like the first image?

Thanks for your tips.

I think the metallic looks mainly comes from the dodge and burn technique. This video shows the technique well. How to Dodge & Burn in Photoshop by Elena Jasic.

I tried to achieve the similar effects of the first image you provided. The left image is before any edits, and right image is after the edits. I hope this is the effects which you are trying to achieve!

1. Lower the saturation by colors. Especially lower reds and yellows to achieve brown skin tone.

2. Adjust the curves.

3. Do the dodge and burn. Done!
