In-Line Double Eyelid - SM Plastic Surgery

In-Line Double Eyelid (In-Line Double Eyelid)

An inner crease (inline) designed low and narrow for a subtle, natural eye area. We also explain the difference from an outline crease and whom it suits.

In-Line Double Eyelid, In short?

The inner-fold design sets the crease low and narrow on the inside of the lid, creating a restrained, natural eye area that does not stand out. It is chosen by those who want to keep a look close to a single lid while adding a little definition. How well a given height and width suits varies with lid thickness, the strength of eye opening and the distance between brow and eye, and it is carried out in combination with a fixation method such as buried suture, natural adhesion or incision. A careful consultation designs a line suited to facial proportion.

Frequently Asked Questions

What kind of line is the inner fold (in-line)?

The line is designed low and narrow on the inside of the lid, creating a restrained, natural eye area that does not show plainly. It is chosen by those who want to keep a look close to a single lid while adding a touch of definition.

How do the inner and outer lines differ?

The inner line sits low and narrow for a natural, restrained impression; the outer line high and wide for a clear, open one. Which suits varies with lid thickness, the strength of eye opening and facial proportion.

Who does an inner fold suit?

It tends to suit those who want a natural eye area or whose lids are on the thin side. Where the lid is thick or eye opening weak, a low line may not show well, so its height is adjusted at consultation.

Can an inner fold come undone over time?

A low line made by the buried-suture method can fade or come undone over time. To improve holding power, combining it with the natural adhesion or incisional method can be considered.

Can an inner fold also be made without incision?

Where the lid is thin with little fat, a low line can be made by the buried-suture method. Depending on the eye, natural adhesion or incision may suit better, and the method is chosen after detailed assessment.

Is recovery from inline double eyelid surgery relatively quick?

The inline design keeps the line low and narrow, so the recovery period depends on the fixation method it is combined with. We generally guide patients to return to daily life after about 3 to 7 days, and swelling subsides at different rates in different people. What we advise varies with whether the line is created by the non-incisional, natural adhesion, or incisional method.

As a man, will an inline double eyelid look obviously operated on?

The inline design places a low, narrow line inside the eyelid so it does not stand out prominently, which is why it is chosen when a subtle change is wanted. The height that suits you still depends on the thickness of the upper lid and the distance between brow and eye. Tell us at consultation how visible you want it to be, and we design accordingly.

How is the fixation method chosen when creating an inline?

If the eyelid is thin we form the line with the non-incisional method, and when more durability is needed we use the natural adhesion or incisional method, combining them according to the state of your eyes. Because inline refers to setting the line low, the fixation method is judged separately from eyelid thickness and fat volume. We advise on the right combination at consultation after examining your eyes directly.

Can an inline be changed to an outline later on?

Changing the height of the line requires a different judgment from creating one for the first time, so we need to check both how the earlier line was made and the current state of the eyelids. Whether it is possible and how it would be done depend on the fixation method and any traces of the previous line. Tell us when and how the earlier surgery was performed and we will explain in detail at consultation.

Does the inline look even lower once the swelling goes down?

Right after surgery swelling often makes the line look higher and thicker than it really is, and the low line settles as the swelling goes down. Since inline is designed low to begin with, it can look even more subtle through this process. We check how the line settles through follow-up observation.

Could an inline make my eyes look droopy?

Because the design keeps the line low, the impression changes with how the height and width are planned, so we consider eye-opening strength and lid thickness together. When that strength is weak, a low line alone may not create definition, and we assess whether ptosis correction should be combined. Tell us the impression you want at consultation and we design accordingly.

My eyes look sleepy. Can an inline make them more defined?

The approach differs depending on whether the sleepy look comes from the absence of a line or from weak eye-opening strength. When the strength is weak, a low line alone has limits, so we first identify the cause through careful examination. Inline is the design chosen when you want to keep a look close to a monolid while adding some definition.

With an inline, is the line visible when I wear makeup?

Inline is a low line that does not stand out prominently when the eyes are open, so how visible it appears changes with how you apply eyeliner or shadow. The impression also shifts with how high and wide the line is set. If you describe your usual makeup style at consultation, we take it into account when designing.

If epicanthoplasty is done at the same time, does the inline change?

The way the line connects at the inner corner can change, so when epicanthoplasty is being considered we plan it together from the line-design stage. Whether combining them is appropriate is judged by the spacing between the eyes and the shape of the eye area. Tell us the look you want and we will advise at consultation on which combination fits.

Does an inline also make the eyes look bigger?

A line can make the eyes look more defined, but because inline is designed low and narrow the change tends to be subtle. It is closer to refining the overall impression than to changing eye size itself, and results vary from person to person. We adjust the height of the line in the design according to how much change you want.
