A Korean plastic surgeon broke down Jin's face measurements online and confirmed that he has the golden ratio. This ratio simply means that "Jin's face consists of 4 equal parts from hairline to eyebrow, from eyebrow to tip of his nose, from the tip of his nose to his jawline. The distance between his nose tip and jawline consists of two equal parts from the nose tip to the centre of his lips and the centre of his lips to the jawline that matches the golden ratio." Makes his nickname of "Worldwide Handsome" that much more fitting.
