Because some people are simply not happy with the way they look! There are two major reasons why people go for plastic surgeries. Some do it to look more attractive while others go for it to make sure they don't end up with scars after an accident. The second reason is most applicable if the injury is on the facial area because no one wants to have a scared face. Additionally, some individuals prefer having professional plastic surgeons work on their faces to reduce the severity of their scars. The second reason has to do with people's discomfort about their looks. Though surgery can be a very expensive option for altering ones looks, it remains the most effective procedure to achieve that, which has helped increase the popularity of plastic surgery.
