The infraorbital rim or infraorbital margin is a border of the undereye area. Retruded infraorbital rims could be detected by dark circles under the eyes. Forward-projecting infraorbital rims are aesthetic as will as high infraorbital rims.
Infraorbital rim retrusion could be masked by makeup. This is used by females to improve their appearance.
Caucasians have relatively retruded infraorbital rims compared to other races.
