What Makes Dimples: The Science Behind the Smile
Dimples are formed due to a combination of anatomical and genetic factors. At the core of what makes dimples is the structure of the facial muscles, particularly the zygomaticus major muscle. This muscle, which is responsible for lifting the corners of your mouth when you smile, can sometimes split into two parts in individuals with dimples. This split creates a slight indentation in the skin above the muscle, which becomes visible when the muscle contracts during a smile. The skin overlying the split muscle is thinner and more tightly connected to the underlying tissue, making the indentation more pronounced. This anatomical variation is what makes dimples appear as charming craters on the cheeks. Interestingly, not all dimples are permanent. Some people have “dynamic dimples,” which only appear when they smile or laugh, while others have “static dimples,” which are visible even when their face is at rest. Another factor that contributes to what makes dimples is the role of collagen. Collagen, a protein found in the skin, provides structural support and elasticity. In individuals with dimples, the distribution and density of collagen fibers may differ slightly, contributing to the formation of these indentations. This interplay of muscle structure and skin elasticity is a fascinating example of how the human body’s anatomy can create unique features like dimples.
Is Having Dimples Determined by Your Genes?
When it comes to what makes dimples, genetics play a significant role. Dimples are often considered a dominant genetic trait, meaning that if one or both of your parents have dimples, you’re more likely to inherit them. However, the inheritance pattern of dimples isn’t as straightforward as it might seem. While some studies suggest that dimples are passed down through dominant genes, others indicate that they may result from a combination of genetic and environmental factors.

What Role Do Dominant and Recessive Genes Play in Dimple Formation?
Dominant genes are those that express their traits even if only one parent passes them down, while recessive genes require both parents to contribute the same trait for it to be expressed. In the case of dimples, the gene responsible for this feature is thought to be dominant. This means that if one parent has dimples, there’s a higher chance their child will have them too. However, because genetics can be unpredictable, not all children of parents with dimples will inherit this trait.
Can Environmental Factors Influence Dimple Development?
While genetics largely determine what makes dimples, environmental factors may also play a role. For instance, changes in muscle structure or skin elasticity due to aging, weight fluctuations, or even injuries can influence whether dimples appear or disappear over time. Additionally, some researchers believe that hormonal changes during puberty or pregnancy might temporarily enhance the appearance of dimples in certain individuals.
What Are the Different Types of Dimples?
Dimples come in various forms, and what makes dimples unique is their diversity. The two primary types of dimples are cheek dimples and chin dimples, each with its own characteristics and causes.
What Are Cheek Dimples and How Are They Formed?
Cheek dimples are the most common type and are typically located on the apples of the cheeks. They occur due to a variation in the zygomaticus major muscle, as mentioned earlier. Cheek dimples can be either dynamic or static, depending on whether they appear only during facial expressions or are visible at all times.
What Causes Chin Dimples and How Do They Differ?
Chin dimples, also known as cleft chins, are caused by a slightly different anatomical variation. They result from an incomplete fusion of the jawbone during fetal development. Unlike cheek dimples, chin dimples are almost always static and remain visible regardless of facial expressions.
Why Are Dimples Considered Attractive?
Dimples have long been associated with beauty and charm, but what makes dimples so appealing? One reason is their rarity. Not everyone has dimples, which makes them a distinctive and eye-catching feature. Additionally, dimples are often linked to positive emotions like happiness and friendliness, as they become more prominent when someone smiles or laughs. From a cultural perspective, dimples are often seen as a sign of youthfulness and vitality. In many societies, they are considered a desirable trait that enhances facial symmetry and overall attractiveness. Celebrities with dimples, such as Jennifer Garner and Chris Pratt, have further popularized this feature in media and pop culture.

Can Dimples Change Over Time?
As we age, our bodies undergo numerous changes, and dimples are no exception. What makes dimples appear or disappear over time is often related to changes in skin elasticity and muscle structure. For instance, as collagen production decreases with age, the skin may lose some of its tightness, causing dimples to become less pronounced.
What Factors Contribute to the Disappearance of Dimples?
Several factors can influence whether dimples fade or disappear entirely. These include:
- Loss of skin elasticity due to aging
- Weight gain or loss, which can alter facial fat distribution
- Hormonal changes during different life stages
Can Lifestyle Choices Affect Dimple Visibility?
Yes, lifestyle choices such as smoking, excessive sun exposure, and poor skincare can accelerate the aging process, potentially affecting the appearance of dimples. On the other hand, maintaining a healthy lifestyle and skincare routine can help preserve their visibility.
How Are Dimples Portrayed in Culture and Media?
Throughout history, dimples have been celebrated in art, literature, and media. What makes dimples particularly fascinating is their ability to convey emotion and personality. In many cultures, dimples are seen as a sign of good fortune, fertility, or a magnetic personality. In modern media, dimples are often used to enhance a character’s charm or likability. For example, actors with dimples are frequently cast in roles that require a warm and approachable demeanor. This cultural significance has helped cement dimples as a timeless symbol of beauty and charisma.
Can Dimples Be Created Artificially?
For those who weren’t born with dimples, modern cosmetic procedures offer a way to achieve this charming feature. What makes dimples artificially possible is a minor surgical procedure known as dimpleplasty. During this procedure, a small incision is made inside the cheek, and a small amount of tissue is removed to create a permanent dimple.
What Are the Risks and Benefits of Dimpleplasty?
While dimpleplasty is generally considered safe, it does come with risks such as infection, scarring, or asymmetry. However, for many individuals, the benefits of achieving their desired look outweigh the potential downsides.
Are There Non-Surgical Ways to Create Dimples?
For those hesitant about surgery, non-surgical options like makeup techniques or facial exercises are available. While these methods can temporarily mimic the appearance of dimples, they don’t provide the same permanent results as dimpleplasty.
