[Etone TV] L-line, V-line, U-line! Types and Characteristics of Jaw Lines image 1

The facial shape trend that is emerging these days

Square jaw.

With its unique atmosphere and charm, its popularity is rising.

In this post,

along with square jaws,

we will look at various jaw line types such as L-line, V-line, and U-line,

and their characteristics.

In the past,

the V-line was considered the standard of beauty,

but now

square jaws are drawing attention again,

like those of actors Lee El and Kim Tae-ri.

There is still a preference for faces that look slim and small,

but rather than a jaw that is too flat,

there is a tendency to prefer facial shapes with a slight angle.

Rather than an always-sharp V-line,

it seems people now prefer natural angles.

When describing face shapes, people sometimes use terms like V-line, L-line, and U-line.

A V-line is

when viewed from the front, the chin tip is pointed and the contour line feels smooth and slim.

An L-line is

when viewed from the side, the angle from below the ear to the most protruding part of the jaw is relatively distinct,

creating a shape with visible angles.

A U-line is

when viewed from the front, the jaw is not especially long or pointed,

and it seems to refer to a face shape that gives a rounded impression.

If you think of a face shape like BLACKPINK's Jennie,

it may be easier to understand.

A V-line generally can give a slim and feminine impression.

But if it is too pronounced,

it can also give a sharp impression.

It is slim and pretty,

but it can end up looking cold.

An L-line has

clear angles below the ear and a jaw line that feels more straight,

so it can create an impression that is somewhat masculine or strong.

Another way to see it is that it can also look intellectual.

A U-line has

a small jaw and a soft feeling,

so it can create a boyish or girlish and youthful impression.

However, it may be a little less likely to look mature.

Of course, these are general tendencies, and they can look different depending on the overall harmony of each person's face.

Some people may consider contour surgery in order to create these facial shapes.

There are some points to be careful about during surgery.

One of the important things is the 'nerve line.'

A large nerve runs through the jawbone, and the surgical range may be limited depending on the location of this nerve.

Surgery is only possible within a safe range so as not to damage the nerve,

and this cannot be known until you come to the hospital.

You need to come to the hospital and have a CT scan or X-ray taken to accurately determine the nerve position and decide the safe surgical range.

I do not think contour surgery is a procedure that completely changes the face and makes it dramatically more striking.

Rather, I see it as a procedure that helps correct facial flaws so that the unique features of the eyes, nose, and mouth can stand out more clearly.

Contour surgery is like a canvas for the eyes, nose, and mouth, which are the main features,

and it helps keep attention from being scattered by uneven contour lines, while adding a softer or sharper feeling to improve the overall impression.
