Chris made the excellent suggestion to use a frequency separation approach to perform basic retouching, as well as adding texture (ie, only to the high frequency components of the image).
In
a thread just a few days ago, you asked the same question as you are asking in the current thread, namely, how to achieve what you called a "polished" or "glossy" look. To elaborate on what I said in that thread, I followed the procedure I outlined in my response in that thread to illustrate how this goes.
First, as I suggested in that thread, one first develops a mask to apply effects (brightening and reduction of saturation) to the highlights area. For the image I chose to use as an example, I was able to get most of the way with just a straight luminance mask, but had to do a bit of burning and dodging to clean up the mask.
Next, I used it on a levels and a vibrance/saturation adjustment layer to brighten and decrease the saturation slightly in the highlights area. A before-after comparison is shown in the animated GIF below.
Also, note that if you are going to get into frequency separation techniques (as per Chris's suggestion), then you should just apply the masked adjustment layers only to the low frequency part of the image. I did not mention this option in that post because, at that time, I didn't think you would be using a frequency separation approach, so a direct approach was easier to explain.
HTH,
