Researchers in related fields include Professor Hammermesh of the University of Texas at Austin. His conclusion is similar: the financial return of ordinary plastic surgery is around 5%. Considering the huge risk of surgery and the unknown long-term effect, this is really not a rational investment method. In addition, avant-garde makeup technology, good dress taste and correct posture of holding your head up and chest out can all have the same effect as cosmetic surgery without risk. More scientifically speaking, fitness and weight loss can enhance physical attractiveness and reduce future medical expenses, which is obviously the most profitable choice. There is only one exception, that is, you already have excellent appearance conditions, and you want to further enhance your competitiveness in the marriage market through plastic surgery, that is, from a beautiful woman to a beautiful woman, then plastic surgery may be a good choice. For ordinary people, plastic surgery is a low return on investment even if it is completely utilitarian. Making up and buying clothes are good substitutes, and fitness is undoubtedly the most cost-effective. Whether to choose plastic surgery is entirely out of personal interest, but plastic surgery is actually releasing another market signal-either your taste is not good enough to decorate your appearance through makeup and clothes, or you don't have enough willpower to stick to fitness, which will obviously have a negative impact on the social level. Of course, these studies are only for academic exchanges. If your girlfriend is really spoiled and wants plastic surgery one day, don't take this article to tell her that plastic surgery is either bad taste or lazy. Just tell her: "Perfect appearance will embarrass plastic surgeons". Remember, remember.
