Eggs have played a storied role in Asian beauty practices since the first millennium. In 600 B.C. China, Zhang Lihua, a concubine recognized for her legendary beauty, was said to have whipped up a facial cream composed of egg white and powered vermilion. And during the last century of the Korean Joseon Dynasty, a guidebook for women called Gyuhap chongseo recorded a beauty regime of mixing eggs in liquor to be applied on the face for glossy jade-like skin.
