Facial asymmetry is a common disorder. It involves a significant difference in the size and shape of one’s facial features. The most common areas affected are the jaw, the eyes, and the cheeks.
You’re either gifted or cursed regarding the asymmetrical face causes. That’s because it comes from a genetic trait pre-determined at birth. Many people born with this trait are well aware of it as children.
As you age, it may develop for various reasons. Before you decide to schedule a consultation, you may be asking yourself, “What causes facial asymmetry? Why am I experiencing this problem now?”
Keep reading to find out how to identify the most common causes of uneven facial features and how to get help.
Genetics
Facial asymmetry can have various causes, including both genetic and non-genetic factors. While it can play a role in facial development and symmetry, it is essential to note that facial asymmetry is often a complex trait influenced by multiple factors. Here are a few ways genetics can contribute to facial asymmetry:
Inherited Traits
Genetic factors can influence certain facial features, such as the jaw’s shape, the nose’s size, or eye placement. Variations in the genes responsible for facial development can lead to differences in the growth and positioning of these features.
Developmental Disorders
Some genetic disorders or syndromes can affect facial development, leading to asymmetry. For example, conditions like Treacher-Collins Syndrome can cause differences in facial structure.
Growth Pattern Genes
Genes involved in regulating bone growth and development can impact facial symmetry. Variations in these genes can lead to differences in the growth rates of facial bones, resulting in facial asymmetry.
Aging
As we age, the symmetry of the face may change. It can be the result of environmental factors, such as sun exposure or the aging process. How facial structures change over time can result in two sides of the face looking different.
For example, one side may sag more than the other. It can be due to the wear and tear on facial structures, cells, and muscles as we age.
Also, we naturally lose facial fat as we age, causing the facial structures to drop or appear thinner. All these factors combine to cause the asymmetry of the face.
Lifestyle Choice
Lifestyle choices can significantly cause facial asymmetry in adults, particularly those genetically predisposed to the condition. Sleeping on one side of the face, smoking or drinking alcohol, and having dramatic fluctuations in weight can all increase asymmetry. The gravitational pull on facial muscles causes drooping, wrinkles, and a visible lack of balance from side to side.
Poor nutrition and a lack of exercise can also take a toll, leaving the face tired and slack. Taking steps to avoid these habits and investing in skin care regimens and dental treatments can keep facial asymmetry at bay.
Trauma
Trauma as a cause of facial asymmetry can be various trauma-related factors. Physical trauma can cause bruising and swelling to one side of the face, which can cause facial asymmetry. In extreme cases, fracture and dislocation of the facial bones can cause asymmetry.
Emotional trauma can also contribute to facial asymmetry. If one side of the face experiences more tension due to an emotional experience, that side will become smaller and contribute to facial asymmetry.
Facial asymmetry due to trauma can vary in severity depending on the severity of the trauma. Treatments vary depending on the type and severity of the trauma but, in some cases, involve surgical, prosthetic, or cosmetic interventions.
Dental Issues
Dental problems, such as malocclusion (misalignment of teeth) or jaw discrepancies, can affect the overall harmony of the face. When the teeth or jaws are not properly aligned, it can lead to an asymmetrical appearance.
The misalignment can alter the jaw’s positioning and affect the symmetry of facial structures. Orthodontic treatments and corrective procedures addressing dental issues can help improve facial balance.

Stroke
A stroke is when the oxygen supply to the brain results in tissue death. When it affects one side of the brain, it can cause facial asymmetry due to an imbalance in muscular activity between the left and right sides of the face.
Facial paralysis is a common stroke symptom, as the muscles may not function. It can result in the development of a drooping lower lip, sagging mouth, or asymmetric eyebrows.
Other effects include asymmetric eye closures, facial asymmetry on eye blinking, and weakened facial expressions. It is essential to seek medical help from a trained physician if facial asymmetry occurs, as it could be a sign of a stroke.
Bell’s Palsy
This condition affects the facial nerve, leading to temporary facial asymmetry. Its main symptom is a lopsided face caused by decreased voluntary movement of the affected side of the face. The condition occurs and can last up to six weeks.
Common causes include viral or bacterial infections, as well as inflammation of the facial nerve. Rarely is it caused by a traumatic incident to the face. Treatment often includes steroids, facial exercises, botulinum toxin, and acupuncture.
Bell’s Palsy can result in significant physical and emotional effects and can be a cause of facial asymmetry. It can lead to difficulty performing oral functions like smiling, speaking, and drinking. Those with this condition must seek treatment and speak with a professional to determine the best care plan for them.
Torticollis
Torticollis is a condition wherein a person’s neck is abnormally tilted and turned to one side. Muscle problems, structural defects, or nerve damage usually cause it.
As a result, a person’s head, neck, and face may be affected. It can lead to an uneven face, visible even at rest.
Know What Asymmetrical Face Causes
In conclusion, facial asymmetry can vary significantly among all individuals and can be attributed to numerous factors such as genetics, aging, trauma, and environmental factors. Understanding what asymmetrical face causes can help patients and doctors work together to develop a personalized treatment plan for each individual for better outcomes.
