As a doctor, I will answer this question briefly. I also use these apps to talk about my simple view: everything happens for a reason. These plastic surgery applications actually developed with the Internet. Now that the Internet has entered various industries, it is essentially to improve the efficiency of the industry. Only in this case can it have more advantages than the traditional way. When these apps or websites appeared, they solved the problem of information asymmetry in the industry. They provided many popular science articles on plastic surgery, provided many beautiful cases, and shared the experience of many beauty seekers who had undergone surgery. Most of them are young users, who can learn a lot of information and experience in plastic surgery, and they can learn the basic information of doctors, surgical characteristics, cases, popular science articles and so on. It provides great convenience for the beauty. The reason why these apps have developed and have such a large number of users shows that they provide value. There are thousands of hospitals on it. Through hospital competition, the price has been reduced a lot, and a lot of profits have been given to beauty seekers, so that they can find good doctors with high cost performance without spending high fees (many young users are students or just graduated, with average economic ability). Of course, there will be many problems. Many users are price-oriented and many very good doctors are on it. Because they can't make a very low price, users don't buy it. Many young and inexperienced doctors attract a large number of users because of their very low prices, and there are also many unsatisfactory or failed situations. I have done a lot of prosthetic surgery in clinic. In fact, they have platforms for hospitals and doctors at all levels, both good and bad, just as we will encounter problems with these hospitals and doctors on the shopping platform, not on the platform, but when we receive and treat other customers offline. So my suggestion is to learn more about plastic surgery and learn how to identify excellent projects and doctors on the platform, not only on the platform, but also in other places and offline. Make a decision after comprehensive judgment, and don't blindly take price as the guide.
