This is an Adobe Premiere Elements "Tips and Tricks" that could be used with any of the versions.
Try using the Drop Shadow effect instead of one of the blur effects on a title that overlays a still or video. On the title you would use one of the shape tools to cover an area of skin. You could draw more than one shape on a title to cover more than one area, but it may be better to use a separate title for each area.
For the Drop Shadow effect, check the box for "Shadow Only." Next use the eyedropper to sample an area of "good" skin color. Presto! Well, maybe not. You can adjust the distance and direction properties to fine tune where the shadow is located, and use the softness and opacity properties to adjust the amount of cover-up.
What I like is that the color is keyframeable, as well as those other properties, and they are all under one effect. You can apply layers [of makeup] by using the effect more than once on a title. You will have to uncheck the "Shadow Only" checkbox for other Drop Shadow effects that come after the first one.
If keyframming isn't necessary, you could do something similar in the title designer by changing the color properties of the shape. For the Gradiant option use "Ghost," and check the Shadow option.
One more thing you may want to do is add a keyboard shortcut for Clip > Enable. That way you can easily toggle between the "before" and "after."
Until later.
