Ever wonder why some people have those little divots in their cheeks while the rest of us just have... flat skin? It’s a bit weird if you think about it. We’ve turned what is technically a facial deformity into one of the most sought-after beauty traits on the planet. Honestly, people spend thousands of dollars on "dimpleplasty" just to get that specific look. But what do dimples mean from a biological or even a cultural perspective?
Most people think it’s just a "cute" trait. It’s more than that. It’s a fascinating glitch in human anatomy involving a muscle with a very long name: the zygomaticus major. Usually, this muscle is a single band of tissue that runs from your cheekbone down to the corner of your mouth. It helps you smile. But in folks with dimples, that muscle is actually split into two.
The Anatomy of a "Glitch"
Scientists call it a bifid zygomaticus major muscle. Basically, it’s a double-ended muscle. One part attaches at the corner of the mouth, and the other part hitches a ride on the skin above it. When you smile, that extra attachment pulls the skin inward. That’s why dimples usually vanish when your face is at rest. They are dynamic. They move.
Is it a "defect"? Technically, yeah. But it’s the kind of defect people actually want, like being born with naturally violet eyes or a photographic memory. It’s a hereditary trait, though the genetics are actually more complicated than your high school biology teacher probably told you. We used to think it was a simple dominant trait. You know, Mom has them, Dad doesn’t, so you have a 50/50 shot.
Real life isn’t that tidy.
Geneticists now realize dimples are likely an irregular dominant trait. This means even if you have the "dimple gene," you might not actually show them. It’s called variable penetrance. Biology is messy like that. Some kids are born with deep indentations that fade as they lose their "baby fat" and their facial muscles lengthen. Others don't see them appear until they hit puberty and their bone structure shifts.
Culture, Luck, and the "Angel's Touch"
Depending on where you are in the world, what dimples mean changes drastically. In many Asian cultures, particularly in China and India, dimples are seen as a sign of good fortune and fertility. There’s this old folk belief that a dimple is where an angel touched a baby’s face before they were born.
It’s not just superstition, though. There is a psychological element to why we love them. Dimples make a face look younger. Because they are associated with babies—who often have them due to excess subcutaneous fat—seeing dimples on an adult triggers a "baby-face" response in our brains. It makes the person look approachable, trustworthy, and less aggressive.
Think about celebrities like Jennifer Garner or Harry Styles. Their dimples aren't just features; they’re part of their personal brand. They radiate a certain kind of warmth. Research in evolutionary psychology suggests these facial markers might have evolved to make our smiles more visible. If you’re a primitive human trying to show a neighbor that you’re friendly and not about to hit them with a rock, a dimple acts like a neon sign for your smile. It exaggerates the expression. It communicates "I’m happy" from further away.
Different Types You Might See
Not all dimples live on the cheeks. You’ve probably seen the "chin dimple," also known as a cleft chin. This is a totally different beast. While cheek dimples are about muscles, a cleft chin is about bone. It happens when the two halves of the lower jawbone don't quite fuse together during fetal development. It leaves a gap, and the skin sinks into it.

Then there are the "Dimples of Venus." Those are the two little indentations on the lower back, right above the buttocks. These aren't caused by muscles or bones, but by a short ligament stretching between the skin and the spine. In the fitness world, these are often seen as a sign of low body fat and good circulation, though mostly, they’re just down to your skeletal structure.
The Rise of Dimpleplasty
Because of the "cuteness factor," the medical world has seen a massive spike in dimple creation surgeries. It’s a relatively quick procedure—about 30 minutes. A surgeon makes a tiny incision inside the mouth, removes a bit of fat and muscle, and then uses a dissolvable suture to tether the skin to the underlying muscle.
But here is the catch: surgical dimples are permanent.
Remember how I said natural dimples usually show up only when you smile? Well, if the surgery isn't done perfectly, those "man-made" dimples stay there even when you’re crying or stone-faced. It can look a bit "uncanny valley" if the tension isn't exactly right. It just goes to show how precise the natural "glitch" in our anatomy really is.
What Should You Actually Do With This Info?
If you’ve got them, embrace them. They are a unique genetic quirk that literally changes how people perceive your personality. If you don't have them, don't sweat it. Most of the world doesn't.
If you are a parent and your kid has them, keep in mind they might disappear. As the facial structure matures and the fat pads in the cheeks (called buccal fat) thin out, the skin can lose that tethering point. On the flip side, some people develop "weathered" dimples or deep expression lines as they age that look like dimples but are actually just the result of skin elasticity changes.
Practical Takeaways:
- Check your lineage: If you're curious about your future kids, look at both sets of grandparents. Since the trait has variable penetrance, it can skip a generation.
- Don't fake it with makeup: You’ll see "dimple hacks" on TikTok using eyeshadow. They almost always look like dirt on your face in person because dimples are 3D shadows, not 2D pigment.
- Skin Health Matters: If you have natural dimples, the skin in those divots can be more prone to trapping oils or sweat. Make sure your skincare routine involves getting "into" the dimple to prevent localized breakouts.
- Consult a pro: If you are genuinely considering dimpleplasty, ensure the surgeon shows you "static" versus "dynamic" results. You want a dimple that appears when you laugh, not one that looks like a permanent hole in your face.
At the end of the day, dimples are just a beautiful accident. They don't mean you're destined for wealth or that you're "better" than anyone else—biologically, they just mean your zygomaticus major decided to take a detour. But in a world of symmetrical faces, having a little anatomical "error" is a pretty cool way to stand out.
