You'll notice a bad plastic surgery job specifically because it is bad. You won't notice a good plastic surgery job because it is good. The fact that you can hold up some examples of bad surgeries doesn't in any way present a defensible case that people therefore shouldn't get it.
This was exactly what I was going to post.
Frankly, if you can tell that someone has had cosmetic surgery, the surgeon is a bungler. (I except the cases where before and after pictures exist, and the reason you can tell is simply that the improvement is too marked to have been achieved any other way.)
There's some tradition in the USA of overdoing facelifts, for example, with patients looking like they've stepped into a wind tunnel. This isn't an argument for not having a facelift, it's an argument for avoiding that surgeon like the plague.
I do understand the argument about anaesthetic and surgical risks, however many aesthetic plastic surgeons are highly ethical professionals, and they don't seem to think the risks are prohibitive.
