The downward rotation of the nasal tip means that the nasal tip cap moves downward or is unstable. The nose of a famous Korean actor belongs to the downward rotation of the nose tip. The so-called "seagull line" refers to the relationship between the nose and the alar when looking at the nose from the front. The ideal position of the nose will be slightly lower than the alar. Lines are like seagulls spreading their wings, hence the name "seagull line".
