Facial asymmetry is a condition in which the two sides of the face are not symmetrical. This condition may be caused by a variety of factors, including aging, trauma, and environmental factors. Facial asymmetry can affect any part of the face from the eyes, lips, and nose, to the jaw and chin.
While some people may have more noticeable asymmetry than others, facial asymmetry is normal and it does not always indicate a serious problem. However, if you have recently noticed a marked change in the symmetry of your face, it may be a sign of an underlying medical condition.
What are the Causes of Facial Asymmetry?
We all have slight asymmetries or irregularities in our faces, but for some people, the asymmetry can be more pronounced. But what causes a person to have an asymmetrical face?
The answer varies, but it could be a combination of factors, including genetics, sun damage, smoking, dental work, and more. Let’s take a closer look at some of the most common causes of facial asymmetry.
Genetics
Having an asymmetrical face can very well be hereditary. If your parents or grandparents have prominent asymmetrical lips, chances are that you may have inherited them too. Additionally, some health conditions, such as cleft lip and palate and vascular disorders, can cause facial asymmetry.
Sun damage
UV rays from the sun can cause spots and patches on your skin. If you spend a lot of time outside—whether you’re working or playing—you’re more likely to get sun damage, which can be unevenly distributed over your face.
Smoking
Smoking is known to cause wrinkles and other visible signs of aging. But, did you know that it can also cause facial asymmetry? A 2014 study revealed that smoking is directly correlated to facial asymmetry.
Dental work
Having a tooth extracted or using dentures can be a cause of facial asymmetry. These procedures can cause a shift in the muscles you use to chew, speak, and smile, which can lead to changes in your facial symmetry.
Injuries
Facial trauma can have a lasting impact on the symmetry of your face. Being hit or punched in the face, especially if it’s on one side, can cause swelling and long-term asymmetry.
Aging
As we age, the face begins to lose its elasticity, which can cause your features to become less symmetrical. Additionally, the fat and skin layers in our faces begin to thin and loosen, which can cause the face to look more asymmetrical.
No matter the cause of asymmetry, it’s important to remember that everyone’s face is different and unique. While facial asymmetry can be a cause of insecurity, there’s no need to be ashamed of your unique features. With the help of a professional, you can explore options to reduce the appearance of facial asymmetry and feel more confident in your appearance.
Common Signs of Facial Asymmetry
Common signs of facial asymmetry include:
- Cheek Retrusion: A condition in which one cheek appears to be more sunken than the other. This can be caused by an imbalance in the facial muscles, genetics or even age.
- Eye Displacement: When the eyes appear to be misaligned or not symmetrical. This can be caused by an irregularity in the shape of the eyes or due to an imbalance in the muscles that control eye movement.
- Eyebrow Lowering: When one eyebrow appears to be lower than the other. This can be caused by genetic factors, age, or even gravity.
- Bone and Forehead Protrusion: When one side of the face appears to be more prominent than the other. This can be caused by an uneven distribution of fat or muscle on the face.
- Nasal Deviations: When the nose is crooked, have a bump, or be off center. This can be caused by structural abnormalities, genetics, or even trauma.
While facial asymmetry can sometimes be a natural occurrence, it can also be caused by underlying conditions such as Bell’s palsy or a form of facial paralysis. If you’re experiencing any of these common signs of facial asymmetry, it’s important to talk to your doctor. They can help determine the cause and provide you with appropriate treatment options.
