The filler depends on what you want. Now it is generally divided into tissue substitutes: silica gel, swelling, artificial skin grafting and autologous sources: cartilage, dermis and fat, all of which are safe. The specific style of rhinoplasty generally depends on your specific situation, not fixed, close to everyone's face and specific situation are different. If you want to go to South Korea for plastic surgery, you can, but your cost will be much higher, and the time to stay in South Korea will vary according to the way you choose, generally ranging from 7- 10 days. Now many plastic surgery platforms are doing this, so you can learn more about it. Personally, I suggest that South Korea's plastic surgery is not necessarily better than China's, not to exclude their technology, but that if there is a problem, you may not be guaranteed. After all, you can consult or find your surgeon immediately in China, but not necessarily abroad.
