Eye plastic surgery is known as a relatively common procedure, but when you look into it closely, there are many factors to consider depending on the individual.

When deciding on double eyelid surgery, you need to carefully think about whether to choose a non-incision method such as natural adhesion or whether an incision method would be more appropriate.

It is also important to decide on the type of line you want.

Types of Double Eyelid Lines

Double eyelid lines are classified in several ways depending on where they start and how high they are.

Representative line types include inline, in-out line, out line, and semi-out line.

✅ Inline

An inline is a double eyelid line that starts inside the epicanthal fold at the inner corner of the eye.

Because it gives a natural look, it is characterized by being barely noticeable after surgery.

It may be suitable for those who want a natural-looking eye shape rather than a glamorous one.

✅ In-out line

An in-out line is a form between an inline and an out line,

and the front part is slightly covered by the epicanthal fold, creating an eye shape that is natural yet defined.

It is considered a suitable shape for East Asians, and people who want a natural but clear look tend to prefer it.

✅ Out line

An out line starts above the epicanthal fold and forms a higher double eyelid line.

It can give a defined and glamorous look, but it may not suit everyone.

Therefore, a sufficient consultation with a medical professional is needed to determine whether it harmonizes with your own eye shape.

✅ Semi-out line

A semi-out line starts at a slightly higher position than an in-out line,

but it is lower than an out line.

It may be suitable for those who want a more defined eye shape than an in-out line, but find an out line too much.

Recently, as more people want eyes that look natural yet defined, its popularity has been increasing.

How does natural adhesion with the non-incision method proceed?

The natural adhesion non-incision method may vary depending on the condition of the individual’s eyes.

In general, it is performed by making tiny holes using a 5-point or 6-point method for fixation.

🔹 A clear line can be created through tight fixation.

🔹 Stability is increased by securing it with a double knot to prevent it from coming loose.

🔹 The height of the line is designed with consideration for the harmony of the individual’s facial shape and features.

In particular, when the hiding technique is applied, the knot is not visible, which can create a more natural impression.

Care must be taken so that not only when the eyes are open, but also when they are closed, there are no noticeable signs of surgery.

Is natural adhesion suitable for everyone?

Unlike the incision method, the natural adhesion non-incision method is known as a relatively simple procedure, but it is not suitable in every case.

🔹 It may not be appropriate if the eyelids are thick or sagging is severe.

🔹 Results may vary depending on the medical team’s experience and skill.

🔹 It is important to choose a line that harmonizes with the individual’s eye shape.

Even with the same natural adhesion method, results can differ depending on the surgeon’s skill,

so it is important to choose a board-certified plastic surgeon with extensive surgical experience.

What line suits me?

Whether it is a semi-out line, an in-out line, or an out line, the line that suits each person can be different.

Rather than simply choosing a trendy line, it is important to select a design that suits your own facial shape and

eye shape.

If you choose a line that does not match your facial shape, you may need to consider revision surgery.

If you are considering eye plastic surgery, it is advisable to make a careful decision after sufficient consultation

with a board-certified plastic surgeon who has extensive surgical experience.

※ Depending on the individual, side effects such as inflammation, bleeding, and nerve damage may occur, so sufficient consultation with the medical team before surgery is necessary.
