What Causes Dimples: Exploring The Science Behind This Cute Trait

Dimples are small natural indentations that can occur on various parts of the body, most commonly on the cheeks and chin. They often become more prominent when a person smiles and are indicated by a slight inward curve in the skin.

How are Dimples Formed on the Cheek?

Dimples that appear on the cheeks when we smile are formed actually due to variations in the zygomaticus major muscle. This muscle, which is crucial for facial expressions, normally runs from your cheekbone to the corner of your mouth. But if you have dimples, it may act a bit differently.

In individuals blessed with dimples, this muscle splits into two bundles. One bundle connects to the corner of your mouth as usual, while the other attaches below it and is attached to the skin above. This unique arrangement causes the skin to dip when this muscle contracts during a smile, giving rise to those adorable dimples.

You can have dimples either on one or both cheeks. And yes, they are often passed down through families. Roughly 20-37% of us have cheek dimples, but this figure can vary depending on where you live. Let’s now explore the different types of dimples that grace our faces.

Different Types of Dimples

There’s more to dimples than meets the eye. Here are three main types:

1. Cheek Dimples: Undoubtedly, these are the most common type and form on your cheeks due to muscle variations. People often find them attractive and they can make smiles more captivating!
2. Chin Dimples: Also known as cleft chins, these dimples are due to a gap in the lower jawbone during development, leading to a noticeable cleft.
3. Sacral Dimples: Located near your lower back, these dimples are usually harmless but may need medical attention if they’re associated with other symptoms.

While cheek dimples steal most of the limelight, chin and sacral dimples are seen less often.

Dimples have a unique place in various cultures, often associated with beauty, luck, or youthfulness. Their relative rarity enhances their desirability, making them a sought-after trait in some societies. Whether on the cheek or chin, dimples are formed through unique muscle structures and genetic factors, making them an intriguing feature that varies widely among individuals.

What is the Genetic Basis for Dimples?

Dimples often leave many people intrigued by their appearance. There are certain genetic factors contribute to their formation. In the past, it was widely held that dimples on the face were governed by a single dominant gene.

However, recent advancements in genetic studies suggest that this belief is far from accurate. According to research, there are at least nine distinct genetic variants that might play a role in the occurrence of dimples. This indicates that the genetics of dimples is not as straightforward as Mendelian inheritance would suggest, and they are often referred to as an “irregular dominant trait”. This means that even siblings may present different dimple patterns or lack them entirely.

The physical basis for dimples lies in the structure of the zygomaticus major muscle, which tends to split into two separate strands in those with dimples. When we smile, the muscle contracts causing a visible indentation or ‘dimple’ in the skin.

Family studies further indicate that the inheritance of dimples follows an autosomal dominant pattern, which means they frequently appear in successive generations within families. However, scientists are still striving to understand the exact mechanisms behind their inheritance.

Why are Dimples Considered Attractive?

Turning our attention towards societal perceptions, it’s no surprise that dimples are considered highly attractive. They are synonymous with youthfulness and a certain captivating charm, which can amplify facial expressions and add allure to an individual’s smile.

Perceptions around dimples vary considerably across cultures. In certain societies, they are admired as symbols of good luck or beauty, enhancing their desirability among people. Their rarity adds to their appeal, rendering a person’s smile more distinctive and thereby memorable.

Moreover, societal perceptions have often linked the presence of dimples with positive traits, adding a touch of allure to their bearers. So, whether you’re one of the lucky individuals with dimples or simply an admirer of these charming indentations, remember that every smile is special in its unique way.

Are there any Dimple-related Complications? How can They be Managed?

Dimples have an undeniable charm and some people even undergo surgical procedures to have these dimples on their face. However, just like any surgical intervention, dimple creation, or dimpleplasty, also comes with its share of complications.

Dimpleplasty is generally safe and straightforward. However, inherent risks such as bleeding, infection and scarring must not be overlooked. Similarly, scarring is a possible outcome but usually minimal; most patients witness little to no scarring after a month.

It is important to recognise these complications to aid in their effective management. Anyone experiencing negative side effects should consult their surgeon immediately. Maintaining good oral hygiene and taking prescribed antibiotics can help prevent infections. Applying ice packs can reduce mild swelling and discomfort after surgery.

Can Dimples Go Away?

Now, you may wonder why dimples occur on your face or whether they can disappear over time. For some individuals, dimples may appear more prominent in their early years and fade as they age. This happens when one loses skin laxity or undergoes significant weight loss as they get older. However, in most cases, this genetically inherited trait does not disappear completely.

On the other hand, weight gain might make the dimples appear more prominent due to excess facial fat. So, while your smile dimples may change over time – become less visible or more pronounced based on various factors – they rarely vanish completely.

Medical and Surgical Options for Dimples

When it comes to dimples on the face, there are both surgical and non-surgical options available for people who seek to create or remove them.

Surgical Option

Dimple Creation Surgery (Dimpleplasty):

• This procedure is generally performed under local anaesthesia and lasts around 30 to 45 minutes. It involves a small incision inside the mouth and the creation of a scar that imitates the natural appearance of dimples.
• Although it primarily aims at creating dimples, this technique can also be employed for the removal or alteration of existing dimples by adjusting the depth and position of the incision and sutures.
• Even though it is generally considered safe, complications can arise, including infections, abscess formation, and scarring. In rare instances, patients may experience substantial swelling or painful complications.
• Proper post-operative care plays a crucial role in minimising risks. This includes maintaining oral hygiene and possibly using antibiotics.

Non-Surgical Option

Dermal Fillers:

• While not a direct method for removing dimples, fillers can alter facial contours and may reduce the visibility of dimples by adding volume to the surrounding tissue. However, this method is temporary and requires constant maintenance.

Individuals contemplating these options should consult with qualified cosmetic surgeons to discuss their goals, understand the benefits of the procedure, and become aware of possible complications. Stay informed and choose wisely!

Top 5 Health Conditions That May Exclude You From Undergoing Dimpleplasty

1. Chronic Illnesses: Individuals with serious medical conditions, such as diabetes, heart disease, or autoimmune disorders, may face higher risks during surgery and complications during recovery. These conditions can complicate the healing process.
2. Blood Disorders: Patients with bleeding disorders or those taking anticoagulant medications may have an increased risk of excessive bleeding during or after the procedure. This can lead to complications that may require additional medical intervention.
3. Infections: Active infections, particularly in the area where the surgery will be performed, can pose significant risks. Surgery should be postponed until any infections are treated and resolved.
4. Smoking: Smokers are generally advised against undergoing cosmetic surgeries, including dimpleplasty, as smoking can impair blood flow and healing, increasing the risk of complications such as infections and scarring.
5. Mental Health Considerations: Emotional stability and realistic expectations are crucial. Individuals with significant mental health issues or unrealistic expectations about the outcomes of the surgery may not be suitable candidates.

While there are no absolute contraindications for dimpleplasty, a thorough consultation with a qualified surgeon is essential to determine suitability for the procedure.
