Hello!

Designing natural beauty with trust.

I am Masataka Fujihashi, a board-certified plastic surgeon.

 

For double eyelid designs, considerations include "how wide to make them" and "whether to make them flared or parallel."PreferencesI think there is.

At our cosmetic surgery clinic, we place great importance on fulfilling your wishes to the greatest extent possible.

However, each eyelid hasInnate structureand there is,Depending on the current state, it may be difficult to reproduce the desired form exactly as requested.

Therefore,IdealCharacteristics of the current eyelidsCarefully rubbing them together while jointly determining a stable and visually appealing line is extremely important.

eyelid thicknessAmount of fatMongolian fold (skin fold at the inner corner of the eye)Degree of skin laxity, andEyelid opening strengthSeveral factors overlap, causing the ideal double eyelid width and line shape to vary.

 

 

Mongolian fold and double eyelid shape

The shape of double eyelids is determined by"How the inner double eyelid appears"is.

The width of this "inner double eyelid line visible inside the black part of the eye" determines the type: a wide width indicates a parallel type, while a narrow width approaches a fan-shaped type.

This "appearance of the double eyelid inside the black part of the eye" is,

Double eyelid width above the pupil × Shape of the skin near the inner corner of the eye (strength of the epicanthal fold)

is determined.

For eyelids with pronounced epicanthal folds,The inner corner of the eye is more easily covered by skin.Even if you try to thread the double line all the way to the inside,Naturally tends toward a mix-typeis a characteristic feature.

 

• Strong Mongolian fold → Difficult to achieve a parallel type,Settling into a fan-shaped to mixed pattern

 

Weak or absent Mongolian fold → Parallel type is also easy to create

 

If you try to force the inner part to show by focusing solely on the double eyelid width, the width will spread unnecessarily,Risks of hamster eyes,Gives a heavy / sleepy impressionsuch risks increase.

Therefore,For those with pronounced Mongolian folds, the range of shapes that naturally appear beautiful is primarily "fan-shaped to mixed-type."will become.

If you want to make it parallel,It is necessary to create a condition where the double eyelid width is easily formed toward the inner corner through an epicanthoplasty.There is.

 

 

"Thickness" isn't just about fat

The thickness of the eyelids,Three layersis involved.

1. Thickness of the orbicularis oculi muscle(muscles directly beneath the skin)

2. Amount of orbital fat

3. The thickness of the skin itself

The greater the total amount, the less likely the line is to dig in,A wide parallel stance is prone to collapse.There is a tendency.

With the incision method, this layer can be carefully adjusted,Even with a wider stance, it's easy to achieve stability.has the advantage of.

Conversely, as the number of these three elements increases, the risk of the implant becoming loose also increases.

 

 

Cases where the incision method is suitable

The incision method allows for secure internal fixation of the double eyelid line,Adjustable thickness of fat, skin, and orbicularis oculi muscleHere's how.

Therefore,

• Thick eyelids

• Want it wide and parallel

• Skin sagging

In such cases,It is easier to control the shape and more stable than buried implants.There is a tendency.

 

 

■ Upper eyelid skinIn cases of sagging

If there is significant excess skin,Even when widened, the lines tend to appear smudged.Therefore,

• Mild to moderate skin laxity ... Double incision + minimal skin excision

• Moderate to severe skin laxity ... Combined with brow lift surgery

We will handle it.

 

 

The Relationship Between Eyelid Opening Force and Double Eyelid Width

The strength of the eyelid opening significantly affects the impression of the double eyelid width.

People with strong eyelid opening force(Originally the type with wide-open eyes)

 ・Even if you try to widen it, it's physically difficult to expand.

 ・If you spread it too much, it can emphasize the eye area excessively, making the impression appear harsh.

 ・Even with a modest width, it still looks wide and open.is a characteristic

People with weak eyelid opening strength(Type with weaker eye opening)

 ・The width itself can often be increased

    ・However Spreading it out too much can make it look sleepy or heavy.

    ・By maintaining a moderate width, it naturally creates a bright impression.

 

Double eyelids are one way to make eyes appear larger.And, like eyelash extensions and eyelash perms, it's a key part of creating your look.

Therefore,Big, wide-open eyes ≠ making them wider.

Large, wide-open eyes = A state where the balance between eyelid strength and width is optimalis.

If you want to improve your eye opening or are concerned about looking sleepy,Elevate eyelid strength through ptosis surgeryIt becomes a necessary means.

Rather than focusing solely on width,Balance with eyelid opening forceis important.

 

 

Summary

The double width is,

Ideal image (parallel/tapered, wide/narrow)  ×  Eyelid condition (thickness / fat / epicanthal fold / laxity / eyelid opening strength)

We will decide by rubbing them together.

Strong Mongolian fold → For a parallel effect, combining with epicanthoplasty provides stability.

Thick eyelids → Buried sutures are less wide, while incisions allow for easier adjustment.

When conditions are favorable Even with embedded designs, the range of possibilities remains sufficiently broad.

Eyelid Opening Force × Width The balance of these elements is the key to determining the impression of the eye area.

Counseling is a valuable time to reconcile your ideal self with what change is possible.
