Photoshop users only need apply. The link jumps to a simple to follow step-by-step tutorial on tutorialblog on how to remove those embarrasing blemishes and make skin in photos look better.
ps - the steps are easily reproducible in GIMP, methinks (so don't feel left out GIMP users).
pps - the rest of the blog is also worth checking out. There are many other tutorials, some on Photoshop but other tutorials are also available on photography, website design and photo effects. Worth a read, but here's hoping more content will be available soon.
