As an external symbol of a person's behavior and cultural characteristics, face has different aesthetic connotations in different countries, different nationalities and different age levels.
In China, it has always been considered that the oval face, commonly known as "oval face" or "duck egg face", is the most ideal. Especially for women, it is more important, because only this kind of face, whether front or side, is harmonious. Besides. The mandibular angle is hidden and the contour line is smooth, which has the aesthetic advantage of curve and can fully reflect the beauty of curve.
On the other hand, as we Asians, the face is not as prominent as that of westerners, and only the five features of the oval face are the most beautiful. Even if you don't dress up, it gives people a delicate and gentle feeling. In other words, it can fully reflect the natural beauty.
At present, with the rapid development of the national economy, people's living standards are constantly improving. Pursuing and advocating beauty has become a social fashion.
Through social influence, people always change their behavior of seeking beauty according to the dominant mode in culture, and always hope that their appearance, especially their face, conforms to the currently recognized standards of handsome men and beautiful women. Therefore, the general pursuit of oval face.
Modern aesthetics holds that "harmony" is the highest form among the three elements of formal beauty.
First of all, harmony in the vertical direction is one of the regular expressions of beauty. Some people think that the heights of 1/3 in the normal plane and 1/3 in the plane should be roughly equal. Others think that the height of 1/3 below the surface should be close to the height of 1/3 inside the surface. But in any case, 1/3 under the surface must be high enough to make the expression natural. This is one of the important foundations of beauty. If the height of 1/3 under the plane is obviously smaller than the height of 1/3 in the plane, a temporary surface impression will be formed. Commonly known as "short chin" or even "no chin". The soft tissue of the chin is often compensatory protrusion, the lower lip is full, and the red lip loses its normal curve, showing a series of aging States. It is more common in patients with deep occlusion of anterior teeth and severe tooth wear, short face syndrome, congenital micrognathia, mandibular developmental disorder caused by childhood trauma, etc. The so-called short face syndrome, which mainly comes from clinical impression, is characterized by short face. It was previously thought that it could not be changed without surgical correction.
On the other hand, facial harmony also needs width coordination. The width of a beautiful person's middle face (the distance between bilateral zygomatic arches) is about 65438+ 0.3 times the width of his lower face (the distance between bilateral mandibular angles). If the width of the lower part of the face is equal to or greater than the width of the middle part of the face, the width is not adjusted. Seen from the front, the bilateral mandibular angle is excessively abduction, the masticatory muscles are hypertrophy and swelling, and the front teeth are too deep and too tight, which gives people a sense of respect. Viewed from the side, the angle of mandibular angle is less than the average value of normal people 120 degrees, and even becomes a right angle. Although this can be said to be masculine for men, it has completely lost its beauty and aesthetic feeling for women.
Symmetry is another regular expression of facial beauty, which can give people a sense of balance and stability and bring beauty enjoyment. Of course, there is no person whose faces are absolutely symmetrical, but if the asymmetry exceeds a certain limit, it will be deformed and destroy the aesthetic feeling of the appearance. It's just the second place compared with facial coordination damage.
