First, a little historical context from celebrity facialist Cecilia Wong: “Jade rollers date back thousands of years,” she explained via email. “The Chinese empresses and emperors were first to use it for smoothing out fine lines and wrinkles and to promote a brighter complexion.” And why jade over other stones? “In Chinese culture, jade is referred to as the ‘stone of heaven’ or ‘the emperor’s stone’ and is a symbol of purity, health, and spirituality. Only the emperors and empresses could afford to use it. Jade is believed to have healing properties, as it expels toxins, heals stressed organs, revitalizes the qi in the body, and slows down prematurely aging skin cells.” All of this, plus it looks super chic on my vanity.
