Open the photo below.
First we'll fix the red eyes by using the Red Eye Removal tool.
Click and drag around the red part of the eye.
Adjust the skin color/tone by using the Filter Hue/Saturation - adjusting the saturation down a bit so the face isn't so red.
Her nose is quite red so we'll use the Dodge tool to lighten it. Zoom in on the nose, and play with the settings - make the brush bigger, reduce the Exposure, and make sure it has a very soft Edge.
You can also Dodge on the teeth to make them a little brighter.
Also use the Burn tool to make her eye brows darker, stand out more.
Save as "correcting" in your Z:>GA8>Photos>Basics folder.
