The tear trough is a dimpled groove that appears on the lower eyelid and occurs in many people at birth, and is more noticeable in people with thin skin around the eyes. The most effective ways to remove the tear trough include collagen injection, autologous fat filling and orbital septum release. 1. Collagen injection: collagen injection is suitable for people who have tear troughs but no bags under the eyes, and a small amount of injection can also improve dark circles while filling the hollows. 2. Autologous fat filling: Since autologous fat is from own tissue, the compatibility of tissue is better and the effect is more lasting. 3. Orbital septum release: Orbital septum release is suitable for patients with both eye bags and tear troughs, removing the tear troughs while also removing the loose skin of the lower eyelids. For patients who want to remove the tear trough, it is recommended to go to regular hospitals in time and standardize the treatment under the guidance of professional doctors.
