Upon discovery of this mask, Byrdie Editorial Director Faith Xue's world was rocked. (You can read all about her Italian beauty experience.) The clay is sourced from Umbria, Italy (otherwise known as the "Green Heart of Italy"), and incredibly mineral-rich, which is how it so thoroughly cleanses and purifies the skin. Sandalwood oil, chamomile flower, and lavender water are also included to calm and soothe your complexion. Just trust us when we say it's so good.
