Having originally studied mathematics, Bouyain later shifted her attention to cinematography. After studying the topic, at the Louis Lumière School of Cinematography, she went on to work as a camerawomen for several films, and eventually directed several of her own.
She wrote her book Metisse façon after researching her African heritage in Burkina Faso. She learned of the history of Upper Volta (as Burkina Faso was known in colonial times) and of children who were born to African women and French soldiers only to be forced to leave their mothers to live in orphanages. The characters in Metisse façon are based on these children.
