Hello, this is Apgujeong Seoul Plastic Surgery.

When you are thinking about your first double eyelid surgery, one of the things you may worry about the most is the double eyelid line.

These days, the most preferred line is the ‘semi-out line,’ while the ‘in-out line’ continues to be widely loved.

For those who still find it difficult to tell the difference even after looking at celebrity reference photos,

Apgujeong Seoul Plastic Surgery would like to explain the differences between the semi-out line and the in-out line through our cases!

When distinguishing between an in-out line and a semi-out line,

the biggest difference is the starting position of the line.

In-Out Line

The 특징 of an in-out line double eyelid is that the starting point of the line begins at the inner corner of the eye and continues naturally.

As shown in the photo above, an in-out line is a line that starts from the beginning of the eye and finishes with some thickness at the end.

The in-out line gives a natural yet refreshing look, so it can be considered a line that continues to be preferred.

Semi-Out Line

A semi-out line double eyelid starts slightly higher than an in-out line.

It starts with the line lifted like an out line, but because the overall height itself is lower, it is called semi-out.

The semi-out line is glamorous but not too overwhelming, so it is popular among those who want more striking facial features.

IVE’s Jang Won-young and world star BLACKPINK’s Jennie, who are very popular these days, have eyes that fall into the semi-out category,

so it can be said that this is a double eyelid line that has recently become popular as a favorite choice among many MZ-generation people.

"Which double eyelid line should I choose?"

When it comes to a double eyelid line, individual preferences differ, and the best results can be achieved by considering how well it harmonizes with the facial features.

To find the double eyelid line that suits you best, careful design during consultation is also necessary.

We recommend visiting a clinic with a plastic surgery specialist who has a strong understanding of eye surgery and professional expertise, and then consulting there!
