It is caused by atrophy and sagging of the soft tissue at the lower edge of the orbital septum, and some people can even extend to the cheek. Lacrimal groove refers to a concave groove that starts from the inner corner of the eye and appears on the nasal side of the lower eyelid. Because of the contrast between the lacrimal groove depression and the surrounding skin, the lower eyelid tissue looks bloated and protruding, which is easy to be considered as pouch, but it is actually only the illusion of deepening lacrimal groove.

Lacrimal groove is generally congenital, and people with thinner eye skin are often more obvious than ordinary people. But the lacrimal groove is usually not obvious when young, because young people have rich subcutaneous fat and tight skin, so there will only be a vague outline.

However, with the increase of age, the subcutaneous fat is shrinking, the skin becomes thinner and drooping due to the decrease of elasticity, the lacrimal groove inside the lower eyelid becomes obvious, and the bags under the eyes are also exposed.

The appearance of lacrimal groove is easy to make people feel haggard, and it can be eliminated by plastic surgery in the following two ways:

1, autologous fat filling.

2. Inject hyaluronic acid.
