The so-called seagull line refers to the relationship between the tip of the nose and the wings of the nose when looking at the nose from the front, that is, the line formed by the tip of the nose and the upper edges of the nostrils on both sides. The ideal position of the tip of the nose is slightly lower than the wings of the nose. The line is like a seagull spreading its wings, hence the name seagull line.

A nose with a seagull line looks delicate and beautiful, but for many people, the columella is retracted, causing the nose wing and the lobule under the nose tip to form an equilateral triangle shape, and the seagull line becomes a horizon line.

The seagull line that everyone likes will appear only when the columella is slightly lateral to the nose a few millimeters, and the lobules under the nose tip are relatively full.
