Third-tier cities are not well shaped. Most people will choose to go to Beijing, Guangzhou, Shenzhen, Chengdu and other big cities with mature plastic surgery industries. The medical care and its supporting resources in big cities are definitely stronger than those in second-and third-tier cities. Similarly, excellent medical and aesthetic plastic surgery talents will also be concentrated in big cities. In the field of plastic surgery, both hospitals and doctors have much more choices than third-and fourth-tier cities. Advanced technology and equipment can also be equipped in plastic surgery hospitals in big cities for the first time. Plastic surgery in big cities can be guaranteed both in effect and safety. Choosing plastic surgery in a big city is responsible for your own safety, time and money. Therefore, cosmetic surgery in third-tier cities is unacceptable.
