Plastic surgery is risky, and once it fails, it may lead to disfigurement. One of the key reasons is that plastic surgery violates our traditional morality. But with the development of the times, cosmetic surgery is not limited to this. First of all, a person has to bear mental and physical stress because of birth defects or acquired accidents, such as burns and car accidents. Plastic surgery is necessary at this time. Secondly, for a person who is not confident about his appearance, his appearance may affect his employment and even his career. His appearance at this time will increase his confidence, that is, increase his chances of success. Moreover, everyone has a love of beauty, even if there is no physical disability, it is understandable to pursue a more perfect self. Finally, cosmetic surgery has gradually become an industry, and its prosperity and development can bring a lot of tax revenue to the country. Therefore, I think plastic surgery is desirable.
