The Face Powder Hag (or Oshiroibaba) is a demon from Japanese mythology. She tries to trick pretty young girls into using her special white face powder, claiming it will make them more beautiful.
Oshiroibaba (or The Face Powder Hag) is an old woman who walks through the snow wearing an oversized hat, leaning on a cane and carrying a vial of white powder. Her wrinkled face is caked in layers of white makeup.
She appears on cold nights, asking pretty young girls if they would like to try some of her special face powder. She says that if they use it to powder their faces, it will make them more beautiful.
However, as soon as the white powder touches their faces, the girls experience a horrible burning sensation. Their skin starts peeling and their flesh starts to rot and fall from their faces, leaving nothing but a hideous skull. Oshiroibaba steals the flesh and uses it for her own purposes.
