You referred to two images that have almost nothing in common. My suggestion would be to ignore the second. Start with the first example and one of your own images. Find a number of other examples that appear similar to that first example.
The first example is kind of solarized, and I would suggest looking at something older where this technique was employed. It probably influenced whoever produced this one.
Now try to find a small number of adjustments that get you somewhat close to the first without introducing undesirable side effects, such as blocked up shadows, excessive local contrast, or loss of detail. By small number I'm thinking at most 5 layers.
If you can do this, then post the results for further feedback. If you can't, pick an easier target and put this one aside to be revisited later. A good place to start might be channel mixer and curves. It's important to note that while the background is really blown out, his skin has a much lower level of contrast. Don't ruin that.
Also the second one uses at least some makeup to get that level of skin gloss and some final color correction for skin/hair in post. It has a lot of post work. If you're asking this kind of question, it's too difficult for now (not necessarily later). Focus on something you can achieve now.
