I've been thinking about doing this since I originally read this thread and finally got around to it. This is my level of post processing of the photos that I take. I like to show as much as I can when I participate in the editing challenges, but this is the steps I have done in my own images. This is basically just revealing the existing layers I have in Photoshop. Nothing is too dramatic (in my mind anyway) and hopefully it is things that are done that you would've just thought the final photo was a really nice photo of a pretty girl (in these cases). Please excuse dodgy hand writing.
And the final image

I apply sharpening to these images after this but haven't added that specifically. In the case on the Maddie one I also adjusted black levels when I came back to Lightroom to get details back into the eye lashes. Also you will see I dual processed the raw file. I made a copy of it. Processed it until I was happy with skin tones. Then on the second processed it purely looking at the make up. This one was much more saturated and made the skin look orange. I then used layers to blend them together. This is a process I saw Julia Kuzmenko McKim do with her raw files. She tries to work with them as much as possible as there is more colour detail in the raw file.
I am still very much a learner with this type of retouching. Still so much more to learn, not only about how to use Photoshop, but what to work on.
