Hello.

This is Obje Plastic Surgery.

If you are considering double eyelid surgery,

everyone wants a result that does not look obvious.

Even if you asked for something natural,

you may have heard stories like

it ended up looking like a sausage eye,

or that after surgery,

it looked even sleepier than before.

When you see those kinds of reviews,

you may start to worry that your own eyes could look unnatural too.

In the end, those of you reading this article

probably came here because you want to know

what the key to an unnoticeable double eyelid surgery is.

So today, we’ll point out that key right away, and explain why unnatural results happen in double eyelid surgery,

as well as what counts as a natural-looking line,

step by step.

If you read to the end,

you will have a much clearer idea of

what must be checked before surgery.

The key to an unnoticeable double eyelid surgery

is not the method, but the 'design'

When people think about unnoticeable double eyelid surgery,

many of them first focus on the surgical method.

"Incisional-less methods are more natural."

"Doesn’t the incision method look obvious?"

But what determines a natural result

is not the surgical method.

It is the 'design' that matches the eye structure.

Eye structure is completely different from person to person.

Just by looking at eye length, skin thickness, amount of fat, and eye-opening strength,

you can see that each person’s eye structure is unique,

with hundreds of possible combinations.

Only after accurately understanding that structure

and designing a line that suits that eye

can an unnoticeable double eyelid surgery truly be completed.

For example, if you create a line with an incisional-less method

on an eye with thick skin and a lot of fat,

over time the eyelid may look puffy

or the line may loosen.

In such cases, the incision method

can produce a much more natural result.

On the other hand, for eyes with thin skin and good elasticity,

the incisional-less method may be more suitable.

Which method is right

can only be determined after first examining the eye structure.

Choosing the surgical method comes after that.

Sausage eyes, sleepy eyes...

This is why they happen

There are three major reasons why unwanted results appear after surgery.

The first is

choosing a line that does not match the eye structure.

"Please give me a semi-out line like a celebrity."

"Please make it as big as possible."

Requests like these are not a problem in themselves.

But if you insist on the line you want

without the structure supporting it,

the result will end up looking unnatural.

Most unnatural-looking eyes are caused by

applying a line that does not suit that eye.

The second is

missing the parts that should be corrected together.

Creating only a double eyelid line

does not mean the surgery is complete.

If the eye-opening strength is weak,

and you only create a line,

the eyes can look half-closed,

resulting in a sleepy appearance.

In such cases, eye correction should be performed together

so that the eyes open properly

and look natural.

If there are wrinkles at the inner corners of the eyes,

emphasizing only an out-line without epicanthoplasty

can make the inner corner look bunched up.

If there is a lot of fat in the eye

and it is not removed,

the eyes can look like sausage eyes,

while removing too much fat

can make the eyes look sunken.

Naturalness is not just about having a pretty line;

it comes from the balance of the entire eye.

The third is

setting the surgical method

first.

If you fix the method first,

such as saying, "Please do only the incisional-less method,"

you may end up unable to choose what is actually needed for that eye.

In this way, sausage eyes are often not simply a swelling issue,

but rather a problem of design and structural judgment.

A natural-looking line,

know the <criteria> first

A natural double eyelid line has

common conditions.

When the eyes are open, the line should not be overly prominent.

When the eyes are closed,

the thickness should not be excessive,

and the line should begin smoothly from the inner corner

without looking forced.

The proportion of the iris showing should not be excessive,

and above all,

it should harmonize with the whole face.

A natural-looking line is not

a line that is simply not obvious,

but one that looks as if it had always been there.

To meet this standard,

you need to accurately understand the eye structure

and go through a process of designing the appropriate height, thickness,

and starting point.

An unnoticeable double eyelid surgery is

ultimately determined by diagnosis and design before surgery.

That is why Obje Plastic Surgery,

before deciding on the surgical method,

diagnoses the eye structure, skin thickness, amount of fat,

and eye-opening strength in detail,

and designs the line based on those findings.

Only when this process is carried out thoroughly

can a natural double eyelid line that harmonizes with the eye structure

be created.

Today, we explained what determines naturalness in double eyelid surgery,

why unnatural results happen,

and what the standard for a natural-looking line is.

Double eyelid surgery is a common procedure,

but it is by no means simple.

Every eye has a different structure,

and only by properly reading that structure

can you achieve a natural result.

Please remember this:

the design that suits your own eyes comes before the surgical method.
