Why Do People Have Dimples? The Reason Some Smiles Are So Darn Cute, Explained


I think we can all agree that dimples are pretty adorable — or at least, desirable. They’re associated with a particular type of female beauty epitomized by people like Jennifer Garner, Ariana Grande, and Miranda Kerr: a sweet, childlike appeal with an air of innocence. We associate dimples with cuteness and babies — an association that child star Shirley Temple and her cute cheek indentations used to make serious bank in the 1930s. (She even starred as a character called “Dimples” in 1936.) But behind these adorable little dents are actually numerous theories as to why some people have dimples — and the science is surprisingly divided.



First off, there are actually two kinds of facial dimples: chin and cheek dimples. As the proud owner of a chin dimple, I can back up the fact that chin dimples are caused by an underlying cleft in the bone of the chin. (The cleft in my skull is so pronounced you can fit an entire thumb in it. Good party trick.) Slightly less happily, the current popular theory among scientists is that cleft chins are actually a result of a hiccup in fetal development, where the left and right sides of the chin haven’t fused together properly in the womb. So Henry Cavill, Jude Law, and Ben Affleck might make the hot lists, but their sultry chin dimples come down to a development problem. Erm. Sexy?



But cheek dimples are a little more complicated. If you’ve been lusting over dimples, doing that thing where you try to deepen your own with a pencil, or have just been staring at Miranda Kerr wondering what the fuss is all about, here’s the skinny on dimples.



Why Do Some People Have Dimples?



It’s generally agreed that dimples are genetic — but there’s an argument about the details. For a long time, dimples were considered a “dominant” genetic trait: if both your parents had them, you’d always develop some cuteness of your own.



Now, however, some scientists are arguing that they’re actually irregular dominant traits — so having two parents with dimples doesn’t appear to guarantee you’ll have them 100 percent of the time. And one specialist, Professor John McDonald, thinks there isn’t enough research to classify dimples as a dominant trait at all. It’s all a bit of a puzzle.



There are also two different theories about what actually causes dimples in the first place. One is that it’s a product of shorter muscles around the mouth, but the more popular theory is that it’s a defect in the facial muscle going by the frankly brilliant name of zygomaticus major. It’s a large muscle in the side of your face, and the dimples are believed to be caused by a divide in the muscle, which is normally all in one piece. The double or bifid zygomaticus means a small dent forms whenever you smile.
