Some are caused by sleeping posture, for example, people who like to sleep to the left will have smaller cheeks on the left than on the right. If you change your posture from time to time, sometimes you sleep on the left and sometimes you sleep on the right, so that one side of your face will not be oppressed often. If you persist, you can improve the asymmetry of your face.

However, self-correction is a difficult and long process. If the facial asymmetry is very obvious, it can be corrected by plastic surgery such as orthodontics and injection of face-lifting needles.

Extended data:

There are many reasons for facial asymmetry, such as development, trauma, pathology, behavior habits and so on. The reason for this is the following：

First, facial asymmetry caused by congenital developmental problems

Asymmetric deformity of physiological development refers to the phenomenon that one side of the face is stunted during development, the other side is full, and the face is asymmetrical after adulthood.

Because this type is hereditary, there is usually no need for plastic surgery. There are also some congenital diseases; For example, hemifacial short syndrome will lead to severe hypoplasia of one side of the face, accompanied by auricle deformity, which requires corresponding plastic surgery.

Second, traumatic facial asymmetry.

If our face is hit by external force, severe trauma may lead to necrosis or scar formation of subcutaneous adipose tissue of facial skin. When we can't perform reduction treatment after facial fracture, facial asymmetry will be caused after wound healing.

Third, pathological facial asymmetry.

There are many pathological reasons. For example, without plastic surgery after facial tumor resection, facial asymmetry may be caused by various tissue defects or organ displacement.

Fourth, facial asymmetry caused by behavioral habits.

In addition to the above reasons, facial asymmetry is also closely related to the usual living habits. For example, if you chew food with only one tooth, the masseter muscles on this side of your face will be more developed, resulting in facial asymmetry. Life is far more than this example, just like breathing, mouth shape, and even bad standing and sleeping posture will affect your face shape.
