A face mold is a fandom term that describes the particular cranial and facial characteristics of a doll. Variations in eye color, hair color and style, and skin tone result in several different unique dolls in the 18" dolls. There are eight different molds that have been released, only six of which are currently in use. The first mold used is referred to as the Classic Mold, and subsequent molds are generally referred to by the first doll to use the mold.
