If you ask me the less you to do your body the better. We are all beautiful like we are. However if it will make you feel better or you are doing it for special reasons as long as is not too extreme is ok. In order not to look fake the goal is that nobody should notice that you did something.
it wont make you plastic.. if having surgery will make you feel better about yourself and your self steem will grow.. go ahead and do it! dont let anyone stop you
like sofia said, plastic surgery is about you! so if you choose to do it in order to feel better about yourself there is no reason for you to feel fake
