Double-Line Incision: You’ve Heard the Term, but What Exactly Is It?

Double-Line Incision?

While some may find the term unfamiliar, many are likely quite acquainted with it.

Those considering revision eye surgery have probably heard this term frequently while doing their online research and visiting clinics.

Dr. Choi Dong-il of Gangnam Seoyeon Plastic Surgery

In particular, the Double-Line Incision (DLI) is a procedure that Dr. Choi Dong-il at Gangnam Seoyeon performs with great confidence.

We will provide plenty of information, including who the ideal candidates are, the surgical method, and details about scarring, so please read until the end!

If you are concerned about double eyelid lines that are too thick, please pay attention.

Additionally, those who fall into the following categories should take note!



First, let me explain the Single-Line Incision!

One line, two lines, three lines, four lines...

Doesn’t the name give you a hint?

Single-Line Incision is...
A new line is created below the existing double eyelid line, and the skin between them is excised. By removing this skin, the scar is eliminated, adhesions are released, and the line is lowered.

This way, the old scar is no longer visible and the line becomes lower, right?


Wait, the Single-Line method also creates a new line?

‘Then isn’t that also two lines...?’


Let’s clarify the Double-Line Incision (DLI) here!

Double-Line Incision is...
- A new double eyelid line is created below the existing one!- The adhesions of the existing double eyelid line are released.- The newly designed line is set in place.- Over time, the old scar fades away.

See? Unlike the Single-Line method, there is no excision process.

This is the biggest difference!


Now you can see why the Double-Line Incision is primarily performed for those who lack sufficient eyelid skin, right?


Wait, you should expect this!

Immediately after a Double-Line Incision, the flesh above the incision line may appear to bulge out!

Some people mistake this for an uneven step or a mistake.


That is not the case.

The bulging part is a mechanism to prevent multiple folds from forming.

The surgical method is shown above.

It is a widely accepted technique, so you can rest assured.

‘When will the Double-Line Incision scar disappear?’

If you ask this, we cannot say it will disappear completely.

However, it will fade significantly over time.


You should keep this in mind when deciding to undergo surgery, right?

Frequently Asked Questions

What is the biggest difference between the double-line revision and single-line revision?

The biggest difference is whether skin is excised. Single-line revision involves excising the skin between the existing and new lines, while double-line revision releases the adhesion of the existing double eyelid without excising skin and creates a new line. Therefore, it is suitable for individuals with insufficient eyelid skin.

Who typically needs double-line revision surgery?

It is suitable for individuals who have insufficient eyelid skin and want to lower a thick double eyelid line. Since it designs a new line by releasing the adhesion of the existing line without excising skin, it is primarily performed as an eye reoperation method when correcting 'sausage eyes' in the absence of excess skin.

Immediately after surgery, the skin above the incision line appears to protrude. Is this a side effect?

No, this is not a side effect or a step, but an intentional measure to prevent multiple folds. Immediately after double-line revision surgery, the skin above the incision line may appear to protrude, but this is part of a widely accepted normal surgical method, so you can be greatly reassured.

Do scars completely disappear after double-line revision surgery?

They do not disappear completely. However, the scars will gradually fade over time. It is advisable to consider that traces of the existing double eyelid line may remain before deciding on the surgery, and they will gradually become more natural after the recovery period.
