Every face is a little uneven. Medical Director Dr Sin Yong explains which asymmetries can be balanced without surgery, which need a specialist, and which need a doctor today.
WhatsApp to Enquire →Key facts ↓An asymmetrical face is normal to a degree: nearly everyone has one side slightly different. Noticeable asymmetry comes from bone and bite, a larger chewing muscle on one side, uneven volume loss, skin changes or nerve weakness. Soft-tissue differences can often be balanced without surgery, using side-specific muscle-relaxing injections, filler or lifting. Bone differences need an orthodontic or surgical opinion, and a sudden droop needs urgent care.
Yes. Every face is asymmetrical to some degree. One eye usually sits a little higher, one cheek is slightly fuller, the nose leans a fraction to one side and the jaw is a little longer on one side than the other. Studies of facial measurements find some asymmetry in nearly everyone, and most of it goes unnoticed by other people. Slight asymmetry is part of what makes a face look natural.
Two things make people more aware of it today. The first is the camera. A mirror shows your face reversed, which is the version you know; a photograph shows it the right way round, so small differences suddenly look wrong. Front cameras held close to the face also distort features, enlarging whatever is nearest the lens. The second is change. Asymmetry that develops or increases over months or years, rather than one you have always had, often has a cause that can be identified and, in many cases, balanced.
This guide explains the common causes of an asymmetrical face, what can be done without surgery, what needs a specialist, and which changes should be checked by a doctor straight away.
Asymmetry can come from any layer of the face, and often from more than one. Working out which layer is responsible decides whether it can be balanced, and how.
| Layer | Common causes | What you may notice | Usual approach |
|---|---|---|---|
| Bone and jaw | Uneven growth of the jaw or chin, a deviated chin, previous injury | Chin off-centre, one side of the jaw longer, tilted smile line | Camouflage with filler in mild cases; jaw surgery assessment for marked skeletal asymmetry |
| Teeth and bite | Crossbite, missing teeth, uneven wear, one-sided chewing | One cheek or jaw looks fuller; jaw clicks or aches | Dental or orthodontic assessment |
| Muscle | A larger masseter on the side you chew or clench on; uneven muscle pull around the brows or mouth | Wider jaw angle on one side; one brow higher; uneven smile | Muscle-relaxing injections placed by side |
| Fat and volume | Uneven fat loss with age, weight change, previous filler | One cheek flatter, one temple more hollow, one fold deeper | Small, side-specific volume replacement |
| Skin and laxity | Sun damage on the driving side, sleeping on one side | More lines or looser skin on one side | Skin quality and lifting treatment |
| Nerve | Previous Bell’s palsy or nerve injury | Weaker movement on one side, uneven blink or smile | Medical review; selective injections can balance the stronger side |
Habits matter more than people expect. Chewing mostly on one side builds that masseter; sleeping on the same side every night creases and flattens the same cheek over the years; and in Singapore, the right side of a driver’s face gets more sun through the car window, which shows as more pigment and more lines on that side.
Non-surgical balancing works on soft tissue: muscle, fat and skin. It does not move bone. The principle is to treat each side for what it needs, which often means different amounts, or treatment on one side only. These are the options used at IN Eternity Clinic.
Previous filler is a common, overlooked cause. Product that has drifted, or that was placed equally on two sides that were never equal, can make asymmetry worse. If that is the case, the first step is often filler correction rather than adding more. The wider question of what shapes the lower face is covered on jawline and face shape.
“No face is symmetrical, and the aim is never a mirror image. The aim is to find the one difference that draws the eye, and balance that.”
Facial exercises are widely promoted for asymmetry, but there is little good evidence that they change face shape. They may make you more aware of habits, such as chewing on one side, and evenly distributed chewing does help reduce one-sided masseter growth over time. Sleeping on your back, rather than on the same side each night, may reduce new creasing on one side. These are reasonable habits; they will not correct a skeletal difference.
Marked skeletal asymmetry, such as a chin that sits clearly off the midline because the lower jaw has grown unevenly, is assessed by an orthodontist and an oral and maxillofacial specialist. Jaw surgery combined with orthodontics is the treatment that actually moves bone. Filler can only camouflage a mild difference, and too much product to disguise a large one tends to look heavy.
General clinical observations used at consultation; they describe what is checked, not any individual result.
Long-standing asymmetry is usually harmless. A new or changing asymmetry can be a sign of a medical problem and should be checked before any cosmetic treatment.
Where any of these apply, the first step is a diagnosis. A cosmetic plan can follow once the cause is known.
At IN Eternity Clinic, Medical Director Dr Sin Yong starts by finding which layers are responsible for the difference you notice, and whether any of it needs a dental, orthodontic or medical opinion first. If soft-tissue balancing suits, treatment is planned side by side and usually staged, with a review a few weeks later before anything is added. The goal is a face that looks balanced in conversation and in photographs, not a mirror image.
Cost depends on which treatments are used, how many areas are involved and whether treatment is staged. It is set out after assessment. The consultation fee is S$120, waived with any medical treatment.

Yes. Nearly everyone has some facial asymmetry, and slight differences look natural. It is worth an assessment if the difference is new, increasing, or bothers you, or if it comes with weakness, numbness or swelling.
A mirror shows your face reversed, which is the version you are used to, while a photo shows it the right way round. Front cameras held close also enlarge the nearest features. Both make small, normal differences look bigger.
Soft-tissue differences can often be balanced: muscle-relaxing injections for a larger masseter or a higher brow, small amounts of filler for uneven volume, and lifting for one-sided laxity. Each side is treated for what it needs. Bone differences need an orthodontic or surgical opinion.
If the difference comes from one masseter being larger, yes, often. A higher dose on the larger side lets both sides settle towards a similar width over several weeks. If the difference is in the bone, injections will not change it.
Filler can balance uneven volume, such as one flatter cheek or one hollow temple, and can visually centre a slightly deviated chin. It is placed in small amounts by side. Large skeletal differences are better assessed for surgery, because too much filler looks heavy.
There is little evidence that face exercises change face shape. Chewing evenly on both sides and not sleeping on the same side every night are sensible habits, but they will not correct a bone difference.
A sudden droop of one side of the face, especially with slurred speech or limb weakness, can be a stroke: call 995. Sudden weakness of one side of the face over hours, with difficulty closing the eye, should be seen by a doctor promptly.
