Five Representative Double-Eyelid Line Types: Which Style Suits My Eyes?

When researching double-eyelid surgery,

terms like

‘inline’, ‘outline’, and ‘in-out line’

can feel somewhat confusing.

“Exactly how are these lines different,

and which line would suit my face?”

is a concern many people have.

To solve this, the first step is to

accurately understand the types of double-eyelid lines

and the characteristics of each.

👁️ Representative Double-Eyelid Line Types

✨ Good fit for

Inline

1. When the eyes look sharp or strong

and you want to soften that impression

2. When you want a natural,

subtle change

3. For students or office workers who need

a neat impression more than a flashy one

in everyday life

4. When you do not often wear makeup

or prefer light makeup

🧑‍⚕️ Important points during surgery

1. If the epicanthic fold is severe,

combining this with epicanthoplasty is necessary

to achieve a natural inline.

2. Results may vary depending on

skin thickness and the amount of

fat on the upper eyelid.

✨ Good fit for

Outline

1. When you are concerned that

your eyes look small

2. When you want a clear,

large-looking eye shape

3. When you enjoy bold makeup

🧑‍⚕️ Important points during surgery

1. If there is a lot of fat on the upper eyelid

or the skin is thick,

forcing an outline can create a line

that looks unnatural and puffy.

2. On the other hand,

if the skin is thin,

the outline may stand out too much

and give an artificial impression.

▶ Therefore, the key is to adjust the line height

to match the condition of the eyes

3. If an outline is designed while

the epicanthic fold remains,

the front part of the line may look pinched

or awkwardly bent.

In such cases,

epicanthoplasty (medial canthoplasty)

should be performed together to make

the line flow more naturally.

✨ Good fit for

In-out line

1. When an inline feels too neat,

and an outline feels too strong,

it is a suitable middle option

2. When you want an impression that is

soft yet defined

🧑‍⚕️ Important points during surgery

1. Whether epicanthoplasty is combined

depends on the degree of the epicanthic fold.

(If the epicanthic fold is too severe,

the front line may be compressed,

resulting in an awkward line

instead of an in-out line)

2. The line height must be adjusted

depending on the thickness of the upper eyelid

and the amount of fat.

If the line transition is not smooth,

it may look pinched

or unnatural.

✨ Good fit for

Semi-outline

1. When an inline feels too subtle,

and an outline feels

somewhat excessive,

it is suitable for those who want a middle ground.

2. When you want both naturalness

and sophistication

🧑‍⚕️ Important points during surgery

1. If the line is too high or

has a sharp angle,

it may look like an outline,

2. On the other hand,

if it is set too low,

it may lose its presence

and look like an inline.

3. The line often starts

slightly above the inner corner of the eye,

so if the epicanthic fold is severe,

the line may be compressed,

creating an unnatural, pinched appearance.

Therefore, it is important to carefully decide

whether to combine it with epicanthoplasty

(medial canthoplasty).

✨ Good fit for

Hidden double eyelid

1. Suitable when you want to keep the cool,

clean look unique to a monolid

while adding just a little more depth,

2. It suits those who want a subtle double eyelid

that looks like ‘their own eyes’

rather than one that is obvious.

🧑‍⚕️ Important points during surgery

1. If the line is too thin,

the surgical effect may be

almost nonexistent.

Before surgery,

be sure to clarify the level of

‘presence’ you want

through line simulation.

2. If there is a lot of fat on the upper eyelid

or the skin is thick,

a low line like a hidden double eyelid

may loosen over time,

or may not fold at all.

A hidden double eyelid gives a natural,

soft impression rather than dramatically

changing the eye shape.

3. If the eyes are small

or look sleepy,

a hidden double eyelid alone

may not be enough to improve the eye shape.

The thinner and lower the line,

the weaker its retention tends to be,

so after surgery, rubbing the eyes,

swelling, and skin elasticity can cause it

to loosen easily,

which is why an incision method with stronger

fixation is generally recommended.

A double-eyelid line is

more than just making a line on the eye.

Because the most natural and beautiful line varies

depending on each person’s eye condition,

including the eye structure, amount of fat,

skin thickness, and epicanthic fold.

Therefore, rather than deciding that one line is

simply ‘good’ or ‘bad,’

it is most important to accurately understand

the style that suits your own eyes,

and make the decision after 충분히 consulting

with a specialist.
