No one may have noticed that Guo Biting and Guo Caijie actually share the same face...

Treasures, look who this is?

A little impressed? Can't remember? So who is this?

Doesn't it feel more like that!

But! None of them are Shuangzi!

The first two are Japanese actress Mirei Kiritani and Kim Jiyuan Liz, a member of the Korean girl group Ive.

Admire the beauty of beautiful women again

Sure enough, good-looking people easily share the same set of beauty genes.

The sheep also took a special look, Liz is not yet 20 years old, about the same age as when Shuangzi first debuted. The same overflowing aura was revealed at the same age of about 20.

However, one of these two is a Kpop girl group style, and the other is a campus youth white flower, with similar styles but some differences.

So here's the problem

Is it possible that Liz looks more like Shuangzi as he grows?

Or, is it possible that she will grow more and more Shuangzi's charm in the future, and then become popular all the way?

After all, Shuang's face is still quite popular in South Korea, and a side photo of Liz that is very similar to her was sealed as a first love face by the Korean Internet.

The sheep studied it carefully, maybe it was really possible (provided that Liz welded his bangs to the brain)!

I believe you have also found that Liz and Shuang are like the lower half of the face

Some treasures may wonder: Why did the sheep say that if she could weld her bangs to death, she might get closer and closer to Shuangzi as she grows?

Isn't the human mandible developing all the time?

It stands to reason that the longer it is, the more likely it is that it will not look like it...

This involves the development and maturity of the jaw. Hold your horses! And listen to the sheep slowly

Face height: the key to sharing beauty genes

First, Liz and Shuangzi revealed the same aura at the same age, as well as similar overall facial movements (especially facial height).

Can you still tell the difference between cool and liz

This means that, at least at the age of 20, the jaw development status is similar (that is, we often say it looks alike).

The development process of the mandible: longitudinal growth extension followed by shortening resorption

Secondly, on the basis of the same natural growth state, the proportion of facial development is similar.

This ratio refers to the ratio from the base point to the angle of the surface and the height of the face, which shows a very high degree of similarity.

Rear height/front height→ face height angle (face type)

This is also why the sheep will say that as long as Liz welds his bangs, he can get closer and closer to Shuangzi as long as he is.

Because at similar ages, not only the absolute value of facial development (front height) is similar, but also the relative value of developmental trend (proportion of facial development) is highly similar.

Even if Shuang has adjusted a lot on the face later, the development ratio shown by the growth trend has not deviated too much from the initial value, so it still has reference significance

The face height mentioned by the sheep just now is a key factor in measuring the maturity of facial development, and the proportion of facial development trends related to face height is the size of the face height angle.

Here, face height is an indicator that indicates the developmental maturity of a person's jaw, and the face height angle can subdivide the facial maturity again on the basis of the face height indicating the developmental maturity of the jaw, and then help us make a general judgment on our own style direction.

The size of the face height allows us to judge at first glance whether a person's style is mature or juvenile, while the size of the face height angle allows us to dig deeper into a person's underlying style.

A bit of a roundabout, isn't it?

Sheep simplification, face height is an absolute value that can be measured directly, and face height angle is an angle, which is a ratio related to face height.

Left: face height, right: face height angle (face type)

The combination of these two factors can explain why some people obviously look mature, but it is not contrary to dress up at a young age.

Left: mature and sharp, right: mature and delicate

The same face height, adjusted face height angle, different styles are presented

Next, let's talk about how to measure the height and height angle of the face, how to use it, and where to use it...

The sheep have been simplified to the greatest extent, and the pack will be eaten with confidence.

First of all, what is the height of the face?

The same word-making structure as height, as the name suggests, is the height of the face.

Let's start with the picture above

Attention!

Next, you need to mobilize some spatial imagination and measure the height with the sheep.

When measuring height, you must stand straight on the flat ground, and the measured data is the most authentic and effective.

We don't have a ground plane, but we have a facial datum, which is the orbital ear plane (FH).

The plane formed by the upper edge of the bilateral external auditory canal and the point of the inferior orbital border is the plane formed by connecting the pieces below the orbit of both eyes to the upper side of the ear holes

In addition to this datum, we will continue to remember three points, namely the nasal root point (N), the anterior nasal spine point (ANS) and the submental point (Me).

At these three points, an extension parallel to the plane of the orbital ear is made, and the vertical distance between the parallel lines is measured, and the proportion of each part of the height can be analyzed.

The vertical distance between the dotted lines is the "face height" of each part

In human terms, with the "facial ground plane" of the orbital ear plane, other points can "stand" on this plane to measure the height.

The deeper meaning of the face height lies in exploring the underlying logic of the facial style from a deeper perspective, learning how to determine the final personal aesthetic direction through the judgment of the maturity of the maxillofacial surface through the absolute value of the surface roughness.

What exactly does face height affect?

Among so many ratios, S-Go/N-Me is the related concept of the face height angle we want to use.

When this ratio is too low, it can correspond to the high angle surface type, and if it is too high, it can correspond to the low angle surface type.

This ratio is the gold standard for evaluating facial growth patterns, and the normal value is about 62%.

In general, a tall face often gives a more mature visual experience, because having a higher face height means having a more mature maxillofacial surface.

In terms of visual perception, most of the time the height of the face will be simply and crudely summarized as "face length"

However, if a tall person is paired with a longer mandibular riser, the posterior height/front height ratio (S-Go/N-Me) can be shortened.

Balance the sense of maturity brought by high surface height, reduce the overall face age, and bring a sense of atmospheric stretch.

High face high with low angle surface type

It is the high tolerance rate brought by the low-angle bone shape that makes the shape more possible

The same goes for low surface height.

If the lower face height is paired with a shorter mandibular branch, it will hide some mature, even shrewd air under the appearance of a seemingly young and juvenile.

Left: face height indicator, right: rear height/front height-face height angle indicator

Typical small faces are low and high

Like Zhang Shaohan is a typical low-plane high, but because the mandibular ramus is shorter, the proportion of posterior anterior height is less than 62%, and the maturity of the high-angle bone type is quite obvious at a young age.

Everyone found that the absolute value of face height can only make a superficial judgment on a person's first impression, while the face height angle can dig deep into the underlying logic of a person's facial style.

This is also why the face with more mature skeletal characteristics shows the characteristics of a younger age on the whole, but the obviously juvenile face reveals a mature atmosphere.

Thanks to the high coordination ratio of the back front, Guo Biting's mature temperament is always fresh and energetic

Although the concept of face height has not been talked about for a long time, everyone has actually been using this concept in daily life.

For example, when you meet a new person, the first thing you say is usually to ask "where are you from", even if you don't ask how much, you will guess the geographical affiliation of the other party.

In fact, this is the application of face height in life, and to a certain extent, it can also explain the regional stereotypes of everyone's appearance characteristics.

In the study of "Anthropometric Methods", the facial features of northern and southern people are comprehensively compared.

First of all, from the absolute value, the head circumference of the Han people in the north and south is similar (it also shows that the skull base of people of the same race is actually similar).

However, the northern Han head, forehead, and lower jaw are a little wider, the face height is higher, the facial features are larger, the nose is more straight, the distance between the five features is larger, and the head above the ear holes is a little longer.

Southern Han have longer heads, wider faces, but wider and longer noses (although the northern nose is straight, but on average it is not as long as in the south), and the lips are thicker.

Left: Average face of northern women, right: average face of southern women

Secondly, from the perspective of relative value ratio, the ratio of face width to head width of the northern Han ethnic group is small, the width of the lips is thin, and the ratio of ear length to width is similar to the north and south.

When these small differences form a macroscopic whole, they form the impression in everyone's mind about the inherent physical characteristics of people in the north and south.

Li Zi's ancestral home is Guangdong (south), Wang Zuxian's ancestral home is Anhui (central), and Lin Qingxia's ancestral home is Shandong (north)

The study of "Anthropometric Methods" studies the differences in the faces of different regional races from the regional level, and also gives us some inspiration: can the face age and even style be adjusted by changing the face height angle?

How to adjust the face height ratio to change the face age?

This question is an in-depth interpretation of how to determine the aesthetic direction of personality through maxillofacial maturity.

However, before answering this question, we must first return to the concept of face height that we talked about at the beginning: at the root of the nose (N), the anterior nasal spine point (ANS) and the submental point (Me) are made as extension lines parallel to the plane of the orbital ears, and then the vertical distance between the parallel lines is measured, and the proportion of each part of the surface height can be analyzed.

In general, the plane of the orbital ear does not change.

The plane formed by the upper edge of the bilateral external auditory canal and the point of the inferior orbital border

That is to say, if we want to adjust the face height ratio to achieve the effect of changing the face age, we only need to work on the back front height ratio (that is, the size of the face height angle).

Like Guo Caijie and Guo Biting, the absolute value of the face height of these two is actually similar, so looking at the front face alone is a mature style.

Solid line: orbital ear plane, arrow: absolute value of face height

However, because the height of the mandibular branch is different (a key influencing factor), in order to widen the distance in appearance, Guo Caijie's shape needs to highlight the maturity of the high-angle bone shape by emphasizing the presence of the mandibular branch;

Guo Biting's styling is to cover the long jaw branch by wearing her hair, retaining and enlarging the high part to weaken the sense of low-angle bone.

Only in this way, during the confrontation in the play, can the tension between the shrewd and self-interested rich second generation and the stubborn noble girl be amplified.

So, if you want to look more mature, you need to reduce the rear front height ratio, that is, either shorten the back height or increase the front height.

In addition to makeup and styling changes, the method of directly shortening the back height mainly focuses on the reduction of the mandibular ramus and the reduction of the soft tissues associated with the lower jaw.

The length of the mandibular ramus is shortened

Left: Low angle type, right: High angle type

In human terms, either osteotomy shortens the mandibular ramus, so that the posterior height is completely shortened;

Either through injections or photoelectric items to tighten the soft tissues of the lower jaw, enhance the light and shadow contrast of the lower jaw, and achieve the effect of visually shortening the back height.

Correspondingly, the method of increasing the anterior height is also divided into lengthening the bone and lengthening the soft tissue.

They are the maxillary LeFort type I osteotomy (a procedure that is generally used when bone correction of the maxillofacial area is required), and the prosthesis or injection to extend the chin can also achieve an increase in the anterior height.

Similarly, if you want to look younger, you need to increase the back front height ratio, that is, increase the back height, or shorten the front height.

The adjustment scheme in these two directions is also similar to the above, except that in the adjustment of increasing the back height, prosthesis implantation or injection can also be performed to extend the back height.

The same height of the face is combined with different heights of the mandibular branch, and the size of the high angle of the face is increased to amplify the calm character

All of the above methods can achieve the adjustment of one's own age.

But in the end, the aesthetics of appearance are rich and diverse, and they are constantly changing. There are similarities in aesthetics between different regions and races, but there are also many differences.

In terms of the aesthetic feeling of the face shape, the high-angle face shape makes people feel temperamental and more free. The low-angle shape has a more youthful and soft feeling, and is sunnier and more affinity.

Kunling: high surface + low angle surface type, Zhang Shaohan: low surface high + high angle surface type

Aesthetics should not be limited by a single factor, for each of us who pursues beauty, what can be done is to maximize their other advantages on the existing basis.

The concept of face height and face height angle is to help us continue to subdivide aesthetic styles on the basis of existing knowledge, so that individual aesthetics are more operable and easy to operate.
