Above are samples of skin textures w/mouseovers. Under certain lighting (or weather conditions), skin should have some texture. Sometimes less, sometimes more. If you have a specific reason to add more texture to skin, or remove the skin texture or grain - for whatever reason - even if it makes sense to only you, then that's ok. However, be careful not to remove texture from skin just because it's easier to blur the skin than it is to improve skin texture. Even a grungy-looking scan can be improved by adding skin texture, as you can see from some of the samples in this gallery. Using blur filters can become a bad habit, because they're easy. For example, here is a really bad scan of Chisato Morishita, one of the most beautiful woman in the world. Her skin texture has been completely obliterated by the scanner, because the scanner thought he was doing the right thing. To many, this is ideal skin. But it doesn't make sense here, because the lighting in this picture would actually increase the appearance of skin texture. Now the skin has no texture whatosever, and the blur was used on the picture as a whole, making things even worse. The picture is almost ruined. In order to fix this scan, someone would have to use a variety of techniques to return some skin texture and fake an unblur of the whole picture, and that's not easy. After those techniques are applied to this picture, Chisato might look like this. But it could've been avoided in the first place had someone not blurred her skin when they scanned it, or when they brought it into ps after scanning. Skin texture is good, so be careful before removing it, since adding it back in is a problem.
