Bird Droppings...Facial? Another Bizarre Treatment

When a bird dropping unfortunately lands on your shoulder it's supposedly good luck. But, would you pay for it to be spread on your face? I came across an article on the "Nightingale Cleansing Mask which includes a powder composed of "sanitized droppings" from the bird. The treatment claims to break down dead skin cells more gently than acid peels. But, I can't help wondering if the droppings are actually more effective or if it's a novelty to get people in the spa. I guess it is made of natural ingredients but many spas offer a variety of natural options like berries and other herbs and remedies. I think I'm going to stick to my usual exfoliator.
