Still hollow under the eyes even after lower eyelid fat repositioning?
The need for microfat grafting under the eyes
Protruding fat and deeply indented tear troughs
can make the area under the eyes look dark and sunken,
creating an overall tired appearance.

Lower eyelid fat repositioning is a procedure that moves bulging fat to sunken areas
to create a flatter appearance under the eyes,
and is an effective way to improve a “hollow under-eye” appearance.
However, some people may still have a hollow appearance under the eyes
even after lower eyelid fat repositioning.
In this post, we will explain in detail
why this can happen!

📢 Why does a hollow appearance remain even after surgery?
In some cases, the indentation below the eyes—
that is, the tear trough—may not be sufficiently improved
even after lower eyelid fat repositioning.
This is referred to as “undercorrection of the tear trough.”
Undercorrection of the tear trough mainly occurs when the skin is very thin
or when there is not enough fat available for repositioning.
In these situations, it can be difficult to sufficiently fill the sunken area
by moving fat alone,
which ultimately leaves some hollowing under the eyes.
If undercorrection has already occurred,
additional fat grafting can be used to supplement the volume.

📢 This makes “prevention in advance” even more important
Of course, improvement is possible through additional fat grafting,
but this ultimately means dividing into two procedures
what could have been completed in a single surgery.
From the patient’s perspective, having to go through the recovery process multiple times
can inevitably be burdensome in many ways.
Therefore, when undergoing the first lower eyelid fat repositioning procedure,
it is most important to anticipate and prevent this possibility.
After thoroughly analyzing the condition under the eyes,
if necessary, performing lower eyelid fat repositioning together with fat grafting
may lead to more satisfactory results.

📢 Regular fat vs. microfat: What is the difference?
The important point here is that
“microfat” must be used under the eyes.
Simply adding fat does not produce the same results in every case.
Regular fat is harvested from the thighs or abdomen
and then purified through centrifugation.
It has relatively large particles and takes the form of small clumps.
This type of fat is suitable for adding volume to areas such as the forehead or cheeks,
where the skin is thicker and the treatment area is relatively deep.
On the other hand, this type of regular fat grafting is not suitable for thin,
delicate areas such as the under-eye area.
If regular fat with large particles is injected under the eyes,
the skin’s surface may look uneven,
or nodules—lumps that can be felt—may develop.

📢 Why microfat is needed under the eyes
Microfat is produced by filtering regular fat multiple times
through special filters or fine cannulas,
resulting in very fine particles.
Its texture is soft, like cream or clay,
and it has the characteristic of spreading evenly.
Because it can spread evenly beneath the under-eye skin
and settle naturally,
it minimizes the possibility of an uneven surface.
It can also significantly reduce the likelihood of nodules developing.
In addition, the stem cells and growth factors
enriched during the process of finely processing the fat
may help improve the skin environment,
so positive effects can also be expected in alleviating pigmentation
such as dark circles.

Lower eyelid fat repositioning is not simply a procedure that moves fat.
It is a process of designing both “volume and texture”
by comprehensively considering the structure under the eyes and the condition of the skin.
In particular, hollowing such as a tear trough
often cannot be addressed with a single method,
so it is necessary to determine how fat repositioning and grafting should be combined.
Ultimately, satisfactory results depend on how precisely the situation is anticipated
and how appropriately a plan is established accordingly.
