Rhinoplasty usually lasts for 6 months to 10 months, while line carving can last for about two years. Rhinoplasty filler is the key to permanent rhinoplasty. Rhinoplasty can be roughly divided into two categories, one is injection rhinoplasty and the other is surgical rhinoplasty. Hyaluronic acid is often used for injection, but injection is not suitable for all nasal types.
