The technique in the link is somewhat flawed in that it also softens the eyes. Compare the eyes in the before and after photo.
The technique I use is a combination of the healing tools in Photoshop and a duplicate layer to which one applies Gaussian blur, then uses the Black Mask technique that I've discussed in several tutorials to paint away the problem areas. If you use a very soft brush and low opacity you can paint till you get it just right. And its non-destructive. You can then sharpen the eyes with the same technique. Or even faster, using the History brush technique.
Here are some examples with Holley Dorrough. The first is the sharp original vesion and the second is the softened version
And here is a side by side of Jill Day using a more agressive use of the technique:
Please note the eyes in each photo.
If you go really agressive, then you can get the porcelain skin effect, but it often doesn't look real.
