Hello~
🌊Your beauty universe! This is Dr. Shim Jeong-hwan from Wevers Plastic Surgery :)🌊


Q: What are the characteristics of an in-out line?

Among double eyelid lines, the in-out line refers to a line that starts 'in' and gradually widens towards the outer corner of the eye.
Generally, when judging a line, it depends on whether the epicanthal fold line at the inner corner of the eye:
☑️Goes inwards
☑️Goes outwards


If it goes inwards, it's called an ‘in-line’.
If the line starts outwards, it's called an ‘out-line’.
Among in-lines, if the double eyelid gradually thins out and is visible all the way to the very end of the epicanthal fold (the inner corner of the eye), that can be considered an in-out line.

Q: So, in what cases does an in-out line suit best?
For semi-out or out-lines, because the line has to be created outside the epicanthal fold, it sometimes doesn't turn out well, or it can look too dramatic and not suit the individual.

However, with an in-out line, the front part of the line goes slightly inside the epicanthal fold, allowing for a more natural look.
As the line extends backward, it becomes larger and wider, giving a refreshing rather than a stuffy impression.🌊

Therefore, for those who struggle to achieve an out-line or semi-out line, but desire eyes that appear larger and more open, we recommend the in-out line. It tends to work well for such individuals.

Q: Are there any cases where an in-out line is difficult to achieve?
Unless the eyes are too sunken or the epicanthal fold is excessively severe, we can generally create a double eyelid to match as much as possible.
However, with non-incisional methods, it might be impossible to create a high line that is visible all the way to the front.

In such cases, an incisional method can be used, often combined with epicanthoplasty or medial canthoplasty, to ensure the front line is visible all the way to the end.

Q: Who are the best celebrity examples of an in-out line, in the director's opinion?

Red Velvet's Irene, actress Im Bora, and influencer Kang Taeri
These three individuals can be seen as having typical in-out line eyes.
If you look at the inner corner of their eyes, the epicanthal fold starts attached, and then the line gradually widens towards the back, doesn't it?
Their eyes look refreshing without appearing overly dramatic or excessively glamorous. It's a moderate level.

Basically, eyes that are naturally large and slightly protruding tend to have large double eyelids that form well and suit them.


Q: What do you think is the reason why the in-out line is the prettiest?

If a semi-out line suits the eyes well, then a semi-out line is probably the best option.
For the in-out line, when trying to create an out-line, if the epicanthal fold area becomes too thick or looks like a ‘sausage eye’, then an in-out line has to be created at a slightly lower height.

With an in-out line, even if there's an epicanthal fold, the line can be created to avoid a ‘sausage-like’ appearance by keeping it on the inner side.
If the front line extends into an out-line, it can sometimes look too dramatic and disrupt the overall harmony with the face.
However, I believe the in-out line suits most people well.

Frequently Asked Questions
What kind of shape is an in-out line double eyelid?
It is a double eyelid that starts from inside the epicanthal fold at the inner corner of the eye and gradually widens towards the outer corner. It combines the natural look of an in-line with the refreshing feel of an out-line, characterized by not looking stuffy.
Who is the in-out line suitable for?
It is recommended for those who find out-line or semi-out-line too flashy or structurally difficult to achieve. It is suitable for those who want their eyes to look bigger and more open, while also desiring a natural harmony with their overall face.
Are there any eye structures that make in-out line surgery difficult?
Yes, surgery can be challenging if the eyes are severely sunken or if the epicanthal fold at the front is too strong. In such eye structures, it may be difficult to create a high front line with only non-incisional methods, requiring an accurate diagnosis from a specialist.
Can I create an in-out line if I have severe epicanthal folds?
Yes, it is possible by combining incisional methods with canthoplasty. Since it may be difficult to make the front line fully visible with non-incisional methods, an incisional approach can be used along with epicanthoplasty or medial canthoplasty to expose the line clearly.
Is there a risk of developing 'sausage eyes' during in-out line surgery?
The probability of developing 'sausage eyes' is relatively lower compared to out-line surgery. Even with epicanthal folds, because the line is created inwards, it is possible to design the line while avoiding the unnatural thickness or 'sausage' phenomenon that can occur when forcibly creating an out-line.
