Well there's nothing really bad about that because it's really an easy and quick way to automatically smooth up rough texture. But if you look at the picture properly, it's loosing quite a lot of important detail on the image. Normal noise reduction software does this by actually blurring the image using extra-fine 'Gaussian' blur filter and there's usually a setting where you can adjust how fine you want the blurring to be. For instance, the more you adjust it to blur, the more noise-less the image would be. Now the good thing about doing this is that you'll get an image resulting almost 100% noise free, but you're loosing the sharpness of the image and also you're blurring the focus of the image resulting a 'soft-focused' image.
*This error happened a lot to teenagers who love editing their photos to remove digital camera noises and also to get rid of pimples or spots on the face before uploading them to Facebook. Hahaha... XD
Adobe Photoshop has really created what human should be happy and proud of, the .ATN (Action file). This intelligent software has the ability to record a series of editing process and save it later on as a .ATN file. It can later on be uploaded to the internet for sharing and also it's file size is really small that none of them I find is more than 100kb. Well still, that doesn't mean downloading the .ATN file does all the refining job for you. Some of the .ATN file require basic Adobe Photoshop knowledge to be able to use them. Here are some examples of what I did with the action files I've downloaded to manually refine the image.
