Using the healing/clone brush, with an added unwrinkle ---
Adding the adjustment layer hue and saturation to color tone the skin...
1. Load your picture and 2. add a blank layer. 3. Check the appropriate layers use box in the Options Bar, Menu: Windows > Options
Photoshop --Sample: Current & Below
Photoshop Elements: Sample all layers
4. Use the clone tool or the Healing tool (In this sample I used the clone tool) to paint on the blank layer with the clone or healing tool (if you aren't seeing changes you may have not selected the "Current & Below" or "Sample all layers" box or the blank layer...)
Before you select the Hue and Saturation adjustment layer use the "Quick Selection tool": in Photoshop it's the W key
In Photoshop Elements you can use the "Selection Brush" or the "Magic Selection Brush" The F key
Use the selection tool to select the face (skin) so that when you then select the Hue and Saturation adjustment layer it'll only work on the skin
This is what it looks like in Photoshop
This is what it looks like in Photoshop Elements
What you need to watch here is if you need to do more retouching, click on the eye for the Hue and Saturation in the layers palette to turn it off...
Do your cloning or healing and when you are done, you can turn it back on... other wise the skin tone won't match...
Remember if you need to reduce a red tone, in the hue and saturation palette, just use the red channel
If you need to build a skin tone palette
go to Adobe's Kuler web site
The color tools are free...
Okay, have fun!
