Hello,
I am Park Jeong-geun,
Director of Faceplus Plastic Surgery Clinic,
specializing in sub-brow lifts.

During consultations,
Many people say, ‘My eyelids are very saggy.’
However, upon actual diagnosis, it is often a change caused by the lowering of the eyebrow position rather than the eyelid itself.

Because the structures around the eyes are interconnected,
when the eyebrows move downwards,
the skin of the upper eyelid may appear thicker or feel heavy when opening the eyes.
Especially after middle age, it is common for the forehead and periorbital tissues to move downwards due to gravity, causing the eyebrows to gradually descend.

In this case, the distance between the eye and eyebrow becomes shorter,
and the upper eyelid folds, making it appear as if the eyelids are very saggy.
What is the difference between eyebrow ptosis and eyelid ptosis?
Eyelid ptosis refers to a condition where the skin of the upper eyelid sags or
fat increases, covering the eye.

On the other hand, eyebrow ptosis is a situation where the eyebrow position itself moves downwards,
and the surrounding eye structures are pressed down together.
Outwardly, the two may look similar,
but the causes are different.
If it is an eyelid problem, skin excision or eyelid surgery may be helpful,

but if the eyebrow position is low, a method of moving the structure upwards through an eyebrow lift may be more appropriate.
Additionally, if the distance between the eye and eyebrow is excessively close,
it can create an impression of a constricted eye area.
Typical situations where a sub-brow lift is needed
A sub-brow lift is a method that alleviates the heavy feeling of the upper eyelid by excising skin directly below the eyebrow and pulling up the muscle layer together.


This method is particularly considered when the eyelid skin appears saggy but one does not want to significantly change the double eyelid line.
It can be helpful in the following typical situations:
First, when the upper eyelid skin covers the eye, making the eye appear smaller. Second, when the distance between the eye and eyebrow is close, creating a constricted impression around the eyes. Third, when one wants to naturally refine the eye area without significantly changing the double eyelid line. |
Because this method utilizes the skin below the eyebrow,
its approach differs from surgeries that directly incise the eyelid line.
Therefore, its purpose is to alleviate sagging skin around the eyes rather than changing the eye shape itself.
Accurate differentiation of the cause is important.
Changes around the eyes often involve several factors working together, such as eyelid problems, changes in eyebrow position, and forehead tissue displacement.

Therefore, rather than judging solely by appearance,
it is important to identify the actual cause.
This is because the appropriate method may differ depending on whether it is eyelid ptosis or a change in eyebrow position.
In some cases, eyelid surgery is suitable, while in others, an eyebrow lift may produce more natural results.

Ultimately, examining the overall eye area structure and choosing a method that suits the individual's facial balance and eye condition
can be said to be the key to creating natural changes.

Frequently Asked Questions
What is the difference between eyelid ptosis and eyebrow ptosis?
Yes, they are different. Eyelid ptosis refers to a condition where the skin of the upper eyelid sags or fat increases, covering the eye. On the other hand, eyebrow ptosis is a situation where the eyebrow position itself moves downwards, and the surrounding eye structures are pressed down together. They may look similar outwardly, but the causes are different.
When is a sub-brow lift necessary?
A sub-brow lift may be necessary when the upper eyelid skin covers the eye, making the eye appear smaller, or when the close distance between the eye and eyebrow creates a constricted impression. It is also considered when one wants to naturally refine the eye area without changing the double eyelid line.
Does a sub-brow lift change the double eyelid line?
No, a sub-brow lift does not significantly change the double eyelid line. This surgery utilizes the skin below the eyebrow, which is different from methods that directly incise the eyelid line. Its purpose is to alleviate sagging skin around the eyes rather than changing the eye shape itself.
How is a sub-brow lift performed?
A sub-brow lift is performed by excising skin directly below the eyebrow and pulling up the muscle layer together. This helps alleviate the heavy feeling of the upper eyelid and naturally improves the eye area.
Is it important to accurately differentiate the cause of sagging around the eyes?
Yes, it is very important. Changes around the eyes often involve multiple factors such as eyelid problems, changes in eyebrow position, and forehead tissue displacement. The appropriate surgical method varies depending on the exact cause, so it is crucial to choose the method that suits the individual.
Is eyebrow ptosis common after middle age?
Yes, it is common. Especially after middle age, the forehead and periorbital tissues often move downwards due to gravity, causing the eyebrows to gradually descend. This can shorten the distance between the eye and eyebrow and make the upper eyelids appear saggy.
