What constitutes “bad” plastic surgery?

If you’re expecting a total transformation, you might be considering a wrong procedure. Plastic surgery is not for everybody. And it’s absolutely not for people who are obsessed about looking perfect. There is no such thing. Sadly, there are people who risk losing their own identities just to be able to achieve something which doesn’t even exist. However, plastic surgery can improve your life significantly if your reasons and timing are correct. You have to consider a lot of factors before deciding to undergo plastic surgery.
Unfortunately, the number of people who are getting obsessed in achieving “perfection” is constantly growing. This is most apparent in celebrities who we notice have suddenly transformed. Maybe it’s the society’s pressure on them to look gorgeous and perfect when under the spotlight, but it’s not unusual anymore that an actress has fake breasts. There are also other ordinary people who became instant celebrities because of their stories of undergoing plastic surgery. There are even reality TV shows that feature women who join to undergo plastic surgeries. But how bad does a plastic surgery has to be for it to be able to consider a failure?
Naturally, death is the ultimate indication of a failed procedure. Other obvious indications are when you’re left with constant pain or even paralysis, or when suddenly your new nose falls off. But sometimes, one look at someone and we know that something is wrong with him or her, but we just can’t quite put our finger on it. How do we determine a certain procedure is a failure for that person?
