Here is the before photo:
Here is my first 'after' photo: I did a bit of a crop and adjusted white balance in Lightroom. In Photoshop, I used the clone tool to get rid of some of the more noticeable blemishes.
Then I used quite a few actions from http://www.mcpactions.com/
I used the 'Magic Skin' action to even out the skin tone. I then used the 'Eye Doctor' to enhance the eyes just a tad bit. I added a vignette using MCP Burnt Edges. I then used MCP Touch of Light to add just a bit of brightening to the skin, just a little bit.
MCP has some GREAT free actions (click the link, really go ahead), I suggest you download them and try them out a bit. That's how I got started and then moved on to some more advanced editing after purchasing a few of her sets.
Same edit (but additional crop and angle) but then used Lightroom preset 'Aged Photo' and made a few adjustments.
