From a personal point of view, I feel that a reason to why teenagers are so obsessed with their looks is caused by the media. Teenagers often see celebrities, or their 'idols', on television, magazines, the papers, and so on. Being their idols, teenagers would want to be like them in how they look and what they wear as portrayed in the media . Hence they would turn to plastic surgery to have even the slightest detail of their face to be similar to their idol.
Another reason is peer pressure. Friends in the same clique would always influence each other. As the saying goes "to follow the crowd" is always a safe thing to do especially to someone who lacks confidence. Or sometimes a slight remark about his looks might cause that person to go under the knife, on impulse. However plastic surgery is not a 100% success. Hence going under the knife might even make you look worse. Moreover, plastic surgery is very expensive.
Being concern about your looks is a normal thing but do not let that concern turn to obsession. I feel that teenagers should not go for plastic surgery. Even after surgery, how can they be truly beautiful, how can they be truly satisfied. After all, beauty is in the eye of the beholder.
