Found on both sides of the mouth for some of us, cheek dimples are considered attractive and ‘genetically dominant’. Around 37 percent of the population are having cheek dimples (in a study of 2300 people).
Cheek dimples are caused by a change in a particular facial muscle called zygomaticus major. Genetics too play an important part for a face to have dimples, which can develop over a lifetime and also disappear.
Cheek dimples are associated with beauty and some cultures consider it a sign of good luck. They also help us communicate better and recognize the intensity of facial gestures in a person.
Some people also opt for surgery to get these cheek bends, something called dimpleplasty.
