Gold, a material regarded as a valuable asset, has been a secret ingredient in keeping the skin smooth and young since ancient times. Historians asserted that the skincare routine of the Egyptian queen Cleopatra is to use a golden facial mask every night before she sleeps. In ancient Rome, people would use cream that is made of gold as a cure for skin conditions. The Empress Dowager Cixi would use a gold facial roller for massaging and rejuvenating her skin for the purpose of extending her youth. Even the Compendium of Materia Medica has recorded that using gold as a medication can stimulate blood circulation and help skin conditions such as scars and inflammations.
