A dimple (also known as a gelasin[1]) is a small natural indentation in the flesh on a part of the human body, most notably in the cheek or on the chin.[2]

Characteristics[edit]

Dimples may appear and disappear over an extended period.[3] Most cultures consider dimples as a sign of attractiveness and veracity.[citation needed] Dimples may be genetically inherited and have been called a simple dominant trait.[4]

Physiology[edit]

Dimples are a facial muscle deformity.[5] Dimples may be caused by variations in the structure of the facial muscle known as zygomaticus major. Specifically, the presence of a double or bifid zygomaticus major muscle may explain the formation of cheek dimples.[4] This bifid variation of the muscle originates as a single structure from the zygomatic bone. As it travels anteriorly, it then divides with a superior bundle that inserts in the typical position above the corner of the mouth. An inferior bundle inserts below the corner of the mouth.
