Want to look as lovely as the ethereal Japanese geisha? The secret may be to smear bird excrement on your face. The geisha facial involves treating the face with uguisu no fun, or powdered nightingale droppings — a secret ingredient of traditional kabuki actors and the geisha. The nightingale droppings are said to "brighten, heal and retexturize the skin due to their natural enzymes and guanine, which imparts a pearly luster to the skin." The treatment is offered for $180 at the Shizuka Day Spa in New York City for an hour-long session. And not to worry — as the Shizuka Day Spa reports, the droppings are sanitized by ultraviolet light before application.
