How to improve asymmetrical face (uneven facial size)

Under normal circumstances, facial asymmetry (uneven face size) can be caused by genetic factors, habitual one-sided chewing, prolonged improper sleeping posture, trauma, mumps, and other reasons. It is recommended to visit a reputable hospital and, under the guidance of a qualified physician, improve the condition through treatments such as facial contouring surgery, botulinum toxin type A injections, liposuction, or medication. Specific analysis is as follows:

1. Genetics

The structure of facial bones and distribution of muscles are influenced by genetics, which may lead to congenital facial asymmetry. Maintaining good daily habits and avoiding exaggerated facial expressions is important. Under medical supervision, facial contouring surgery can be performed to adjust facial bone structure or use fillers to improve symmetry. The typical reference cost for facial contouring surgery ranges from 20,000 to 100,000 RMB per session. Improvement is generally noticeable within 2–3 weeks after surgery, but potential side effects may include infection and bleeding.

2. Habitual One-Sided Chewing

Consistently using one side of the teeth to chew food over a long period may lead to facial asymmetry. It is essential to chew food evenly on both sides and undergo regular dental check-ups to promptly address dental issues. Botulinum toxin type A injections may also be used under a doctor's advice. This treatment works by injecting botulinum toxin to induce masseter muscle atrophy, thereby slimming the face. The typical reference cost for botulinum toxin type A injections ranges from 2,000 to 12,000 RMB per injection. Results usually become visible 1–3 weeks after injection, but possible side effects include facial stiffness, unnatural expressions, and pain at the injection site.

3. Prolonged Improper Sleeping Posture

Continuously sleeping on the same side may also contribute to facial asymmetry. Adjusting sleeping posture to avoid prolonged lateral positioning and using pillows with appropriate height and firmness is recommended. Liposuction may also be considered under medical guidance. This procedure uses negative pressure suction combined with physical and chemical methods such as ultrasound and high-frequency electric fields to remove localized subcutaneous fat deposits, helping to correct facial asymmetry. The typical reference cost for liposuction ranges from 20,000 to 50,000 RMB per session. Improvement is usually seen within 1–2 weeks post-surgery, but possible complications include hematoma and worsening facial asymmetry.

4. Trauma

Injuries from traffic accidents, falls, or sports-related incidents may cause facial trauma, resulting in uneven facial size. Symptoms may include fractures or soft tissue damage. Follow medical advice to use medications such as ibuprofen sustained-release capsules, cefradine capsules, or safflower oil for treatment.

5. Mumps

Mumps is typically caused by viral or bacterial infection of the parotid glands. Continuous inflammation and irritation of facial tissues by bacteria can lead to swelling and uneven facial appearance, often accompanied by symptoms such as fever and loss of appetite. Follow medical instructions to treat with medications such as ribavirin granules, pudiqing anti-inflammatory oral liquid, or compound honeysuckle granules.

To prevent and improve facial asymmetry, it is important to maintain healthy lifestyle habits, chew food evenly on both sides, adjust sleeping posture, avoid injuries, and maintain good oral hygiene.
