In the past, plastic surgery was not accepted by the public and not common. However, in the　modern society, the average age of having plastic surgery is decreasing every year. Thus, it　can be seen that this phenomenon is becoming more and more common. This research paper　aims to investigate deeply teenagers’ viewpoints on plastic surgery and explore the modern　teenagers’aesthetic. In addition, we want to let people understand the advantages and　disadvantages of plastic surgery. And we also offer some useful information to study the　effect of having plastic surgery. Through our study, we hope that not merely teenagers but　also adults can get a deeper understanding of plastic surgery and correct their aesthetic　biases.
