The cost of surgery is not the main thing, but the safety and rationality of surgery are the main things. Surgery is best performed in a regular cosmetic hospital. Don't go to a beauty salon for the sake of cheapness, especially an informal beauty salon that doesn't belong to a medical institution, which is prone to problems. Moreover, doctors who play hyaluronic acid without formal training are prone to nasal skin necrosis, even nasal dorsal skin necrosis, and even arterial embolism, which can also lead to blindness, hemiplegia and even death.
