We've heard of different masks that work wonders for the face, from ingredients in our kitchen to mask masks with weird ingredients like bull semen, fish eggs or even bird glaze. Even the latter is a favorite of Victoria Beckham, who is known for taking great care of her skin and body.

When Victoria visited Japan she was amazed at the beauty and cleanliness of the skin of Japanese women and learned that treating birdwatching is their secret. Beckham has not been wearing this mask since. Not only she, but her husband David is also a fan of this mask.

The bird's glaze mask, precisely the whistle, collected from the Japanese islands of Kyushu, is considered one of the most effective skin care products. According to people who have used it, the mask leaves its face shiny and serves as an exfoliant.

Dried under UV light, bird excrement is mixed with rice bran and water in the spa and applied to the face. This mask works because of an enzyme that penetrates the dead skin of the face. It also acts as an exfoliant by removing dead cells, leaving the face fresh. The price of this treatment in New York varies, but averages to 135 pounds.
