What Are Dimples?
How Are Dimples Formed?
Cheek dimples are formed by a genetic mutation or alternation in a facial muscle called the zygomaticus major. In people with dimples, this muscle divides into two separate bundles. The two bundles of muscles are also directly attached to the blanketing skin.
When the zygomaticus major muscle pulls upward to smile, the attached skin is also pulled. Dimples are formed because the separated muscle bundles pull in slightly different directions, causing an indentation.
