Double-Line Incision Method: How Does It Differ from Single-Line Incision?

Surgical methods for lowering thick double eyelids are divided into single-line incision (excision method) and double-line incision.

At Gangnam Seoyeon Plastic Surgery, we break down the differences between the two methods, suitable candidates,

and common misconceptions.

---

■ The Bottom Line First

The double-line incision method lowers the crease by creating a new incision beneath the previous scar without excising the existing double eyelid scar.

It is a meticulous procedure that releases the adhesions formed over the old scar

and re-engineers the eyelid so that it folds along the new line.

The key difference from the single-line method lies in whether the previous incision line is excised or preserved.

If there is sufficient skin laxity, the single-line method is considered;

if skin is lacking or if the line needs to be lowered significantly, the double-line method is chosen.

Undergoing a double-line incision does not mean ptosis correction or fat grafting is mandatory.

At Gangnam Seoyeon Plastic Surgery, concurrent procedures are performed in fewer than 5 out of 100 double-line incision patients.

---

■ What Is the Double-Line Incision Method?

The precise medical definition of the double-line method is

"lowering the double eyelid line without excising the previous scar."

When a double eyelid crease appears overly high or thick after surgery,

this procedure releases the adhesions folding at the previous incision scar

and creates a new incision line beneath it to lower the crease.

It is called "double-line" because the original scar line remains intact,

while an additional incision line is created beneath it.

Ultimately, the eyelid folds along the new, lower line,

naturally covering and concealing the previous high scar.

---

■ When Is Double-Line Incision Needed?

Here are 5 cases where lowering a thick double eyelid line is recommended at Gangnam Seoyeon Plastic Surgery:

① When the double eyelid line is too high and needs to be lowered

Cases where a previous surgery set the crease excessively high,

or where natural folds are disproportionately high relative to eyebrow distance.

② When the crease is high accompanied by deep scarring

Cases where thick scar tissue formed at the previous incision site,

making the line look not only high but also stiff, unnatural, and indented.

③ When thick eyelids resemble "sausage eyes"

Cases where eyelids appear puffy and saggy due to excessive muscle or soft tissue manipulation,

causing skin above the crease to bulge out like a sausage.

④ When the crease is too high relative to the distance between the eyebrows and eyes

Cases where the space between the eyebrows and the eyelid line is disproportionately narrow on the overall face.

Correction is needed when the height does not harmonize with facial proportions, even if the absolute height is not extreme.

⑤ When ptosis causes the crease to appear high and exposed

Cases where weakened eye-opening muscles cause the eyelid to droop,

leaving the crease fully exposed and appearing artificially high.

Lowering the line without addressing underlying ptosis may not resolve the issue,

making an accurate preoperative diagnosis essential.

■ Single-Line vs Double-Line Incision — How Do the Methods Differ?

Techniques for lowering thick double eyelids are mainly divided into single-line and double-line incision methods.

The choice of procedure depends on remaining eyelid skin and overall eye condition.

[ Single-Line Incision — METHOD A ]

A method that excises the existing incision scar directly.

The skin between the new line and the existing scar is removed,

lowering the crease while excising the old scar.

Pros:

- Produces a clean, single line in many cases.

- Lower risk of developing multiple/triple creases compared to the double-line method.

- Relatively straightforward surgical technique.

Cons:

- Requires sufficient remaining eyelid skin since skin tissue is excised.

- If excessive skin is excised when skin laxity is deficient,

it can result in severe, irreversible eyelid complications.

- Often difficult to apply, except in cases where patients had high lines in their youth and developed excess skin with age.

[ Double-Line Incision — METHOD B ]

A method that leaves the previous incision scar untouched and makes a new incision beneath it.

Adhesions from the existing double eyelid line are released, and tissues are rearranged to fold along the new lower line.

Pros:

- Can be performed even when eyelid skin is deficient.

- Advantageous when a significant reduction in crease height is desired.

- Additional revision surgeries remain possible if needed in the future.

Cons:

- Leaves two scar lines.

(Existing scar + new incision line)

- Risk of multiple folds/creases forming due to readhesion influenced by the old scar.

- Requires an experienced, highly skilled plastic surgeon to execute safely.

Comparison: Single-Line vs Double-Line Incision:

Dr. Dong-il Choi of Gangnam Seoyeon Plastic Surgery has presented multiple times at academic conferences on eyelid crease lowering surgery, including the double-line incision technique.

The optimal technique is determined after a direct anatomical evaluation of skin availability and eye conditions.

■ 4 Common Myths About Double-Line Incision — The Answer Is Always NO

Searching for double-line incision often brings up vague fears regarding complications.

Here are clear answers to common misconceptions addressed at Gangnam Seoyeon Plastic Surgery.

Myth ① "Double-line incision is the last resort"

→ NO. On the contrary, single-line incision involving forced skin excision can be the true final option,

because once skin is resected, further revision becomes extremely difficult or impossible.

The double-line method preserves skin tissue, allowing additional revision procedures if needed later.

Myth ② "Ptosis correction must always be performed together"

→ NO. While ptosis correction is sometimes recommended to prevent multiple folds,

routinely combining it is unnecessary in many cases.

Resolving high creases with double-line incision alone without multiple folds is Gangnam Seoyeon's core principle and surgical skill.

Myth ③ "Fat grafting must always be combined"

→ NO. At Gangnam Seoyeon Plastic Surgery, fewer than 5 out of 100 double-line incision patients require concurrent fat grafting.

Even when fat grafting appears necessary at first glance, many cases do not actually require it,

and unnecessary concurrent procedures can complicate recovery.

Myth ④ "Step-off scarring is unavoidable"

→ NO. The natural overlapping of skin above the lowered incision line is often mistaken for a step-off scar.

Even individuals who have never had eyelid surgery can show

the exact same appearance when their crease height is naturally low.

This is a natural eyelid anatomical structure, not a surgical scar.

---

■ The Truth About Step-Off Scarring

After a double-line incision, skin may naturally drape slightly over the incision line.

While this is sometimes called a "step-off scar,"

it is actually a normal structural characteristic of eyelids seen even in individuals with naturally low creases without surgery.

As the line is lowered, it is completely normal for overlying skin to drape over the incision,

and mistaking this for a surgical complication is a common misconception.

However, since true step-off deformity caused by scar tissue must be distinguished,

it is advisable to discuss this thoroughly during your preoperative consultation.

■ 3 Core Principles of Double-Line Incision at Gangnam Seoyeon Plastic Surgery

Here are the 3 key principles upheld at Gangnam Seoyeon Plastic Surgery when lowering thick double eyelids:

① Precise Evaluation by an Experienced Board-Certified Plastic Surgeon

Whether single-line or double-line incision is suitable, and whether concurrent procedures are needed,

is determined after directly assessing skin laxity and eyelid tissue conditions.

② Tailored Design Factoring in Eye Shape, Condition, and Full Facial Harmony

Rather than merely lowering line height,

we design an optimal crease by considering eyebrow distance and facial balance.

③ Thorough Planning + Delicate Surgery to Minimize Tissue Damage

Double-line incision is a precision surgery executed right beneath the previous scar tissue.

We minimize tissue trauma to prevent readhesions and achieve a clean, natural crease without multiple folds.

Dr. Dong-il Choi has lectured multiple times at scientific conferences

on the topic of lowering thick double eyelids (double-line incision method).

■ Frequently Asked Questions (FAQ)

Q1. What is the double-line incision method?

A. The double-line method lowers the crease by making a new incision below the previous double eyelid scar without cutting it away.

It releases the adhesions from the former high line and repositions tissue so the eyelid folds along a new, lower line.

It is called double-line because two lines exist: the previous scar plus the new incision line.

Q2. Which is better: single-line or double-line incision?

A. Neither method is universally superior;

the right choice depends on your remaining eyelid skin and eye anatomy.

If there is plenty of skin laxity, single-line incision is suitable; if skin is deficient or significant lowering is required, double-line incision is ideal.

An accurate anatomical evaluation is essential prior to deciding.

Q3. Do multiple creases develop after double-line incision?

A. It is true that double-line surgery carries a risk of multiple folds due to potential readhesion.

However, combining ptosis correction or fat grafting is not unconditionally required to prevent this.

When performed delicately by an experienced surgeon,

double-line incision alone can successfully prevent multiple creases in most cases.

Q4. Is step-off scarring inevitable?

A. The appearance of skin draping over the new incision line as the crease lowers is a normal structural feature also seen in individuals with naturally low creases who have never had surgery.

This is natural eyelid anatomy, distinctly different from scar-induced step-off deformity.

This draping may appear more pronounced the more the line is lowered.

Q5. Can revision surgery be performed again after a double-line incision?

A. Yes. Because double-line incision does not excise skin tissue,

eyelid skin is preserved, allowing further revisions if necessary.

Conversely, single-line excision removes skin, meaning repeated procedures can cause severe skin deficiency, complicating further corrections.

Q6. Can patients who had non-incisional (suture) double eyelid surgery undergo double-line incision?

A. Double-line incision can be performed in such cases as well.

However, suture removal may be considered first for buried suture methods,

so the ideal approach is determined after examining eyelid status during consultation.

Q7. How long is the recovery period after double-line incision?

A. Stitch removal typically takes place between 4 to 12 days,

and returning to everyday activities is usually possible in 3 to 7 days.

Natural results settle in around 3 to 6 months.

Stitch removal timing may vary depending on the extent of surgery.
