1. 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. 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 is not pouch, but it will make pouch more obvious.

2. Because of the contrast between the lacrimal groove depression and the surrounding skin, the plastic treatment of lacrimal groove pattern makes the lower eyelid tissue look bloated and protruding, which is easy to be considered as pouch, but it is actually just the illusion of deepening lacrimal groove. Once you have dark circles, you will look very tired and seem to wake up.
