Inner Double Eyelid Surgery Guide: Natural Adhesion vs. Incision Method, Which Line is Right for Me?

The appropriate method for inner double eyelid surgery varies depending on the individual's eye shape and skin thickness. From a natural in-line to a defined in-out line, it is important to clearly understand the difference between natural adhesion and the incision method to find the 'Custom Fit' line that suits you best. Learn in detail about the eye surgery standards and safety systems proposed by a specialist with 22 years of experience.

Inner Double Eyelid Surgery Guide: Natural Adhesion vs. Incision Method, Which Line is Right for Me?

Characteristics of Inner Double Eyelid Surgery for a Natural Impression

Eyes with double eyelids tend to give a clearer and softer impression compared to monolids. Recently, rather than unconditionally large and glamorous eyes, there is a growing preference for inner double eyelid surgery that corrects the eye shape while preserving one's individuality. Even for the same eye surgery, it can be divided into various types, from a natural in-line to a defined out-line, depending on the desired style. The results can also vary depending on the presence of an incision and the method used to create the line.

At 345 Plastic Surgery, we do not just follow trends; we aim for 'Custom Fit Double Eyelids' that find the most harmonious line by reflecting each individual's anatomical characteristics.

Choosing a Surgical Method: Natural Adhesion vs. Incision Method Comparison

To determine the most suitable inner double eyelid surgery method for you, it is necessary to accurately assess the condition of your eyelids. The characteristics of the two representative methods are as follows:

  • Natural Adhesion: Suitable for those who want a natural line whether their eyes are open or closed. It is recommended for individuals with less eyelid fat and thin skin, allowing for fixation without an incision, and has the advantage of a relatively quick recovery.
  • Incision Method: Performed when a clear and defined line is desired, or when strong fixation without the worry of the fold loosening is needed. More stable results can be expected if there is a lot of eyelid fat or thick skin that requires the removal of unnecessary tissue.

Types of Double Eyelid Lines That Suit Me

The height of the starting and ending points varies depending on the shape of the eye, which greatly affects the overall image.

  • In-line: A shape that starts with a portion of the Mongolian fold at the front of the eye covered. It is the most similar to inner double eyelid surgery and looks very natural.
  • Out-line: A line that starts higher up than the inner corner of the eye, giving a Westernized and glamorous feel.
  • In-out line: An intermediate form between the in-line and out-line. It is a sophisticated line that starts naturally from the inner corner and gradually widens toward the outer corner.

1:1 Customized Diagnosis Points at 345 Plastic Surgery

To complete a harmonious eye shape, 345 Plastic Surgery precisely diagnoses the following four key elements:

  1. Checking the condition of surrounding tissues such as fat and muscle
  2. Considering the overall facial proportions and the position of the eyes
  3. Measuring the size and exposure level of the pupils

Frequently Asked Questions

In what cases is the natural adhesion method suitable for double eyelid surgery?

The natural adhesion method is suitable for individuals with less fat in the eyelids and thin skin, allowing for fixation without incision. It is recommended for those who desire a natural line both when opening and closing their eyes, and it has the advantage of relatively fast recovery.

Can the natural adhesion method be used for surgery even if the eyelids are thick?

No, if you have a lot of fat in your eyelids or thick skin, the incisional method is more suitable. The incisional method can remove unnecessary tissue to create a clear, distinct, and stable line without worrying about it coming undone.

What are the types of double eyelid lines?

There are three main types of double eyelid lines: in-line, out-line, and in-out line. The in-line is similar to a natural inner double eyelid, while the out-line gives a Westernized and glamorous look. The in-out line is a middle form of these two, creating a sophisticated line.

How does Samsao Plastic Surgery perform customized eye surgery?
