A method of forming a cosmetic product by back injection molding is disclosed. The method includes providing a pan having at least one removable wall therein. Each removable wall forms at least two compartments in the pan, with each compartment having apertures therein. The method also includes injecting a first liquid cosmetic through a first of the apertures; injecting a second liquid cosmetic through a second of the apertures, in which the first and second liquid cosmetics may be the same or different; setting the first and second liquid cosmetics without compaction; and removing the at least one removable wall. The present invention also includes pans having breakaway or removable spacer walls, and pans having frame-like structures with open bottom panels. The present invention further includes methods and devices for setting and forming the surfaces of the resulting cosmetics.
