The liquid that leaves the nozzle is not simply water with a fragrance. It is a precisely balanced mixture of solvents, polymers, and plasticizers, and the way that mixture interacts with the surface of the face, as well as with the environmental conditions of the room, is the entire technical story. This is the starting point for understanding the category.
