Order lines and mouth lines can be realized by hyaluronic acid filling, autologous fat filling and line carving. The metabolic period of hyaluronic acid filling is generally 6-8 months, which needs multiple injections to maintain.

According to the doctor's technical level, there are 1-2 years, 3-4 years and 5-4 years.
