The commonly used materials for rhinoplasty are prosthesis and hyaluronic acid. Prostheses are divided into silicone and swelling, both of which are permanent. Generally, a complete recovery period of 1-3 months is required, and a hyaluronic acid tube takes 6- 12 months, which is not permanent and does not need a recovery period. No matter what kind of plastic surgery, the key is to choose hospitals and experts with good skills to do it.
