The methods of removing lacrimal passage include injection of hyaluronic acid, autologous fat filling and swelling filling of lacrimal passage. These three methods are all safe and effective methods to improve lacrimal duct. Each way has its own advantages and disadvantages, and beauty seekers can choose the way that suits them according to their own situation.

Hyaluronic acid filling lacrimal groove: quick effect, less trauma and short recovery period. But with the maintenance of time, the effect is not permanent.

Autologous fat fills the lacrimal ditch: it is taken from itself and will not cause rejection and allergy. But there is a question of survival rate. Therefore, some beauty seekers may fill it once or more.

However, it is prone to infection and other problems, so filling lacrimal passage with swelling method will have higher technical requirements for doctors.
