A nose is simplified to a dot or line in the middle of the face because that's all the brain needs to see to register it as a nose. And adding detail to that simple nose doesn't add appeal the way detailing eyes or lips does, because most people usually don't have their attention drawn to someone's nose the same way they pay attention to "pretty eyes" or "sexy lips".
