V-Shaped Face: What Actually Makes an Asian Face Look Slimmer?

Two faces can measure almost the same across the cheekbones and the jaw, and one can still look noticeably slimmer.

How slim a face looks depends less on any single width than on its outline. That outline is shaped by how broad the face is at each level, how it narrows towards the chin, how long it is for its width, and how clearly the jawline is drawn. A jaw can be made narrower without the face looking slimmer. A face can look slimmer without the jaw changing at all.

What is a V-shaped face?

"V-shaped face" is not a medical term. It describes an outline: a face that is fuller at the cheeks and narrows smoothly through the jaw to the chin.

The closest clinical description comes from the Asian Facial Aesthetics Expert Consensus Group, a panel of clinicians who treat Asian patients. In 2016, it described the oval face as a smooth, egg-shaped curve running from the forehead through the temples, around the cheeks, past the angle of the jaw and along the jawline to the chin, "without indentations or projections in the line". It named an oval face with a neat V-shaped jawline as a current ideal for the female Asian face, and noted that beauty is influenced by customs, traditions and trends.

Two things follow from that. The definition is about how smoothly a line runs. It says nothing about how narrow any part of the face should be. And it records a cultural preference as clinicians saw it in 2016. It is not a description of anatomy, and it is not a standard that any face has to meet.

"Asian" is not one face either. The panel's own definition covered East and Southeast Asia and left out the Indian subcontinent. Most of the studies cited in this article measured Chinese, Korean or Taiwanese faces; where a study did not, the article says so. In Singapore, where Chinese, Malay, Indian, Eurasian and many other faces are seen side by side, no single outline describes an Asian face.

What makes a face look slimmer?

A face tends to look slimmer when its outline narrows smoothly from the cheekbones towards the chin, in proportion to the length of the face, along a clearly drawn jawline. How wide the face is matters, but it is only part of the picture.

Asian Facial Architecture™ reads this through four properties of the outline. They are a clinical way of organising what the eye sees, not a validated scientific classification:

• Width: how broad the face is, and where: at the temples, the cheekbones or the angles of the jaw
• Taper: how the outline narrows from the cheekbones towards the chin
• Length: how tall the face is for its width, including the height and shape of the chin
• Definition: how clearly the jawline reads as a line, which depends on the soft tissue over it and changes with age

Most of the studies reviewed for this article measured attractiveness rather than how slim a face looks. One exception comes from research on perceived weight. Coetzee and colleagues found that two proportions were related to body weight: face width relative to face height, and cheekbone width relative to jaw width. Observers used these proportions when judging how heavy a face looked. The faces in that study were Caucasian and African, so it does not show how Asian faces are read. It does show that people judge the weight of a face partly from its proportions.

Attractiveness research adds a second point. In a study of photographs of 450 young Han Chinese women rated for attractiveness, higher ratings went with narrower cheekbone and jaw width, but with greater width at the temples. It measured attractiveness, not slimness, and only in that population. Even so, the faces rated most attractive were not simply narrower everywhere.

Slimness is read in the outline, not measured across it.

Wide, square, round, short, heavy or undefined: six different concerns

When people say their face looks wide, they are often describing something more specific. Six appearances are commonly described this way. In a mirror they can look alike. They differ in what the eye is actually picking up, and several of them are not about width at all.

The table explains those differences. It is not a self-test. Many faces combine two or three of these, and the same appearance can have more than one cause beneath it. Telling them apart in a particular face takes an examination.

Only some of these are mainly a matter of facial width. In the others, a narrower jaw may leave the feature you actually notice unchanged.

Where the width seems to come from the cheekbones, High Cheekbones vs Wide Cheekbones explains why the part of the cheekbone that looks prominent is not always the part that makes a face wide. How facial width is measured, and why photographs change it, is covered in Why Does My Face Look Wide?. How the support along the jawline loosens with age has its own timeline.

Does a longer or more projected chin make a face look slimmer?

It can change how the width above it is read. A longer chin is not automatically a slimmer face.

The chin is where the outline of the face ends. Its height, its width and how far it projects all affect how the face narrows towards it. Some of this is geometry. Two common measures of facial width compare it with facial height, so the same width over a taller face measures as relatively narrower. A narrower chin brings the two sides of the outline closer together at the bottom, and a broad chin keeps them further apart. Whether either change looks slimmer in a particular face is a matter of clinical judgement. None of the studies cited here tested it.

The 2016 consensus panel also described adding projection to features along the centre of the face, the chin among them, as creating "a visual illusion of 'narrowing'" across the whole face. That is expert opinion drawn from clinical practice, not a measured result.

A chin can also be made too long or too prominent for the face around it. A change that looks right from the front may not look right from the side, where chin and jaw read as a single line.

Can botulinum toxin to the jaw make a face V-shaped?

It can reduce width that comes from the masseter, the main chewing muscle at the corner of the jaw. It cannot create a V-shape in a face whose width comes from somewhere else.

When botulinum toxin is injected into the masseter, its primary target is the muscle itself. Its facial-slimming effect comes primarily from reducing muscle bulk. It does not address the width of the cheekbones, the length of the face or fullness elsewhere in the face.

So a face can still look wide after jaw-slimming treatment. The width may be mainly bone. The widest point may be the cheekbones. Or the appearance may be round, short or heavy rather than muscular. How much the masseter contributes is a diagnostic question, and it is best answered before treatment.

Can a jaw be made too narrow?

It can be narrowed beyond what suits the face. The evidence here is limited to one preference study, one clinical observation and expert opinion. None of it comes from studies of treatment outcomes.

In the preference study, Wu and colleagues took a photograph of one Taiwanese woman, standardised its proportions and changed only the width of the jaw on screen, from 65 to 90 per cent of the width across the cheekbones. Among 203 Taiwanese raters, the 75 per cent version scored highest and the 70 per cent version second. The most tapered version was not the most preferred. One altered photograph cannot set a target for anyone. It does show that more taper was not always rated better.

Kim and colleagues, reporting more than a thousand masseter treatments in Asian patients, noted that thinning the masseter can make the cheekbones and the angles of the jaw look relatively more prominent. A jaw reduced beneath wide cheekbones may therefore make the face look more angular at the cheek rather than slimmer. That second step is clinical reasoning, not a measured finding.

Age changes the balance too. The 2016 consensus panel noted that in older patients, with age-related volume loss and reduced skin elasticity, reducing the masseter can worsen facial appearance, with hollowing and jowl formation. This is expert opinion, not a measured outcome.

The aim is a lower face in proportion to the face above it. That is rarely the narrowest one possible.

Is a V-shaped face right for every face?

No. A V-shape is one outline among many that can be balanced and attractive. Whether it suits a particular face depends on the rest of that face: how wide the cheekbones are, how long the face is, the shape of the chin. In some faces, a broad chin or a defined jaw angle is part of what makes the face balanced.

Chin shape also differs between the sexes on average. In a CT study of 275 Korean patients, most women had a pointed chin and most men a round or square one. That describes the shape of bone in one sample. It is not a guide to what any face should look like.

The Asian Facial Architecture™ perspective

Asian Facial Architecture™, Dr. Gan Lee Ping's framework for reading each face against its own structure, begins a request for a slimmer face with the whole outline. Where is the face widest? How does it narrow towards the chin? How long is it, and how clearly is the jawline drawn? Only then comes the next question: which structures are responsible?

That order matters because treatments act on structures. Reducing a muscle, adding projection, treating soft tissue and reshaping bone are different interventions for different causes. One local treatment can be the whole answer for one face and the wrong one for another. Sometimes no treatment is the right answer.

The treatment should follow the architecture, not the trend.

Preference studies and measurements describe faces in a sample. They cannot set the right outline for an individual face, for the same reasons that the golden ratio cannot.

Before Choosing a Face-Slimming Treatment in Singapore

In Asian Facial Architecture™, the first question is not "How do I make this face narrower?" It is "What is the eye reading as width?"

An in-person assessment answers that by looking at the face from the front and in profile, at rest and in motion. It then works through what is creating the impression, what could reasonably change, and what is better left as it is.

Sometimes the most useful finding is that nothing needs to change.
