Why do some people get dimples?
Human BiologyFacial Anatomy
Quick Answer
Dimples usually happen because a facial muscle is slightly shorter or divided in a way that tugs on the skin. That creates a small indentation when smiling.
The Full Story
Cheek dimples are a normal anatomical variation, often linked to the structure of the zygomaticus major muscle. In many people, the muscle or its attachment pulls the skin inward when they smile. Dimples can run in families, but their inheritance is not as simple as a single dominant gene in all cases. They are harmless and may become more or less noticeable with age or changes in facial fat.
