First of all, I will disagree with the others and say your touchup looks fine. Most people will not even notice because they did not have the "before" pointed out to them, like those on this thread did.
Secondly, I don't know why the complicated suggestions, when all you have to do is use the Clone Tool, set to Lighten, and set the Opacity at whatever suits you best.
You can always use the Blur Tool after to improve the cloning effects.
Playboy centrefolds have had major touchups for years, and nobody complained.
