What causes double eyelids to loosen? Is it 'this'?
- Dr. Park Si-hyeon’s summary

Hello.
This is Objet Plastic Surgery.
A double-eyelid line that once looked clearly defined
can gradually become faint over time,
and at some point, you may notice
that one side has loosened.
This happens more often than you might think.
Seeing the line in the mirror
fade day by day
can feel unsettling.
Today, for those of you in that situation,
I’ll explain why a double-eyelid line may appear to loosen
in three main ways.
If you read to the end,
it may help you find the right direction.
Cause of loosening double eyelids?
'A line that doesn't suit my eyes'
Let me start with the conclusion.
The most common reason is
forcing a line that does not match your eye structure.

When people think about why a line loosens,
they often assume,
'it was just a failed surgery.'
But in reality,
there are many cases where things were already off
at the stage of designing the initial line.
Everyone is born with different eye lengths,
different skin thickness,
the amount of fat in the eyelid area,
the strength of the eyelid-opening muscles,
and even the degree of the epicanthal fold.

This is why the same line can produce different results.
In particular, a flashy semi-out line
or a design that simply copies a celebrity’s eyes
is a typical case that can lead to
loosening of the double eyelid.
If you try to force a line
that your eyes cannot properly support,
the sutured area cannot withstand that tension
and may gradually loosen,
or it may appear faint as the line becomes blurred.
In the end, the issue is not the line itself,
but the result of copying the appearance
without finding a line that suits your own eyes.
If it keeps loosening after buried suture surgery?
The reason is 'here'
When looking into double-eyelid surgery,
people often think deeply about
whether to choose the buried suture method or the incision method.
Getting this choice wrong
is another reason why the line can appear to loosen.

Many people tend to think,
'buried suture is natural,
and incision is burdensome,'
but in reality,
it is not that simple.
The buried suture method
is a way of creating the line with fine thread.
If the skin is thin,
there is not much fat,
and the eyes are not sagging,
a clear line can be created with buried suture alone.
Recovery is also relatively quick.
On the other hand, the story changes
if the skin is thick,
there is a lot of fat in the eyelid area,
or the skin has sagged to some degree.
If buried suture is applied to these eyes,
the weight of the skin, fat, and tissue makes it difficult
for adhesion to form stably,
and the line may loosen more quickly than expected.
That is why, in such cases,
the incision method is also considered.

It removes the necessary amount of skin,
fat, and muscle,
and directly creates the space
where the line can settle,
so depending on the eye condition,
it may help the line last longer.
Unlike the common belief that
'incision always looks obvious,'
if it is performed to suit your eye condition,
it can actually lead to a more natural result.
Among people whose double eyelids keep loosening,
there are also cases where the eyes were better suited to the incision method from the start,
but buried suture was chosen and the same issue kept happening.

What if the line is formed but still looks loosened?
The real 'cause' is elsewhere
In some cases where the line appears loosened,
the adhesion has not actually come apart.
The line is still in place,
but it is hidden by other factors,
creating what is known as a 'false loosening.'
A typical case is when the eyelid-opening strength is weak.

If ptosis is present,
the completed line is covered by the upper eyelid
and gradually becomes obscured.
Unlike an actual separation of adhesion,
the line itself is still there,
but it is more like it has been buried under the upper skin.
In such cases,
eyelid correction should be performed together
to compensate for the weakened eye-opening strength
so that the line appears in the right position.
Conversely, if the eye-opening strength is already sufficient
and eyelid correction is added too aggressively,
the eyes may look overly wide
or leave an artificial impression.
That is why eyelid correction is not something that suits everyone;
it should be decided carefully based on the condition.
Next is the epicanthal fold.

For those with a strong epicanthal fold at the inner corner,
the front part of the double eyelid may look cramped and hidden,
so the curve can appear broken.
In such cases,
adding an epicanthoplasty to help the line flow
naturally can create a more harmonious result.
The amount of fat also needs to be checked.
If there is a lot of fat in the eyelid area,
the upper part of the line can look congested,
and it may be difficult for the line to form deeply,
so some reduction may be needed.
However, if too much fat is removed,
the eyes may look hollow,
or give a tired, aged impression,
so finding the right balance is important.

Only by examining these various factors together
and forming the line accordingly
can the result settle comfortably
without the double eyelid loosening.
Today, I summarized why a double-eyelid line may appear to loosen
from three perspectives.
First, when the line does not suit my eye structure.
Second, when the chosen surgical method does not match the eye condition.
Third, when the line is formed
but appears loosened because it is hidden by other factors.
If you look only at the line,
it is easy to keep repeating the same issue,
so I hope you will keep that in mind.

When Dr. Park Si-hyeon of Objet Plastic Surgery performs double-eyelid surgery,
she carefully examines the eye structure,
including skin thickness, the amount of fat,
eye-opening strength, and the condition of the epicanthal fold,
then determines the surgical approach that best matches the eye.

She designs the surgery by checking one by one
whether buried suture or incision
will settle more stably in the patient’s eyes,
and whether eyelid correction or epicanthoplasty
should be performed together.
To prevent a return to loosened double eyelids,
I recommend calmly checking the line that suits your own eyes first.
