Korean Double Eyelid Surgery: Incisional or Non-Incisional?

If you are researching Korean double eyelid surgery, you have probably met two terms already: incisional and non-incisional. The harder questions are which one your eyelids actually need, and how many days you must stay in Seoul before flying home. We answer those questions in the consultation room every week, and this guide gives you the same explanation in writing.

Double eyelid surgery creates a crease in the upper eyelid. At Banobagi we choose the method only after looking at skin thickness, fat, the muscle that lifts the eyelid and where your brow rests. That choice then sets your operation time, your stitch removal day and the length of your trip.

In this guide you will learn:

• How the incisional and non-incisional methods differ in operation time, anaesthesia, stitches and recovery
• Which eyelid types usually suit each method
• When ptosis correction or canthoplasty is added to the plan
• What recovery looks like day by day, how long to stay in Seoul, and when revision is considered

01What is Korean double eyelid surgery?

Korean double eyelid surgery creates or strengthens a crease in the upper eyelid. It is one of the most common cosmetic operations in South Korea. A defined crease can make the eyes look more open, and people with hooded eyelids may find eye makeup easier to apply, because hooded lids tend to smudge liner and shadow.

It is not the same as a standard blepharoplasty. Blepharoplasty for ageing eyelids mainly removes excess skin or fat for a more rested look. Double eyelid surgery focuses on the crease itself: its height, its shape and how firmly it holds.

Korean eyelid surgery techniques were developed around Asian eyelid anatomy, including thicker skin, the way fat sits around the eye and the epicanthal fold at the inner corner. Our eye surgery team works from three principles:

• Function first. Every eye procedure begins with how the eyelid opens and closes.
• Your natural identity. The result should reveal your own features, not conceal them.
• A refreshed look. The aim is that people notice you look rested, not that you had surgery.

If you want to read more about crease design, our article on creating a natural-looking double eyelid covers it in detail.

02Incisional vs non-incisional double eyelid surgery: how do they compare?

Both methods aim for a natural-looking fold. They differ in how the fold is fixed and how much tissue can be adjusted.

Non-incisional double eyelid surgery makes 5-7 micro holes along the designed line. Unnecessary tissue and fat are removed, and the eyelid is fixed through the holes with a double knot method. The knots sit on the muscle rather than the skin, which lowers the chance of the fold loosening over time.

Incisional double eyelid surgery opens the eyelid along the designed line. Excess skin, fat and muscle are partially removed depending on your skin condition. The eyelid skin and muscle are then firmly tied together and the incision is closed with fine stitches.

These figures describe the usual course. Your own recovery depends on your skin and healing, and results vary between individuals.

Durability differs too. Incisional methods generally offer longer-lasting results. With non-incisional surgery the sutures can loosen over time in some cases, and a touch-up may be needed later. Ageing, brow descent and large weight changes can soften any crease over the years.

03Which method suits your eyelids?

The method follows the eyelid, not the other way round. In some cases the non-incisional method is not suitable because the upper eyelid has thick skin and fat tissue. That is why we confirm the method in person, even when photos look clear.

Non-incisional usually suits you if

• You want to avoid an incision if possible
• Your eyelid skin is thin and not droopy
• You want natural-looking double eyelids
• You are on a tight schedule and want a quicker recovery
• Visible scarring is a concern for you

Incisional usually suits you if

• You want a clear, well-defined double eyelid
• Your eyelid skin is thick and droopy
• You have excess fat and muscle on your eyelids
• Your eyelids are sunken and a fold does not form easily
• You were unhappy with a previous surgery and want a more secure, longer-lasting fold

General candidacy points apply to both. Double eyelid surgery is considered when you have monolids and want a defined crease, or when your existing crease is faint or asymmetrical. You should be at least 18 years old and in good health.

For a longer comparison of the two approaches, see our article on advanced double eyelid techniques.

There are cases where we say no. If your eyelid skin is thick, droopy or fatty, we do not recommend the non-incisional method even when that is what you came in asking for, because that tissue is what the incisional method is planned for. Adjusting the plan while we look at your photos is easier than treating a crease that has loosened.

04When are ptosis correction or canthoplasty combined?

A crease alone does not change how strongly the eyelid opens or where the eye corners sit. When the examination finds a separate problem, a second procedure can be planned in the same session.

Ptosis correction is for eyelids that droop because the lifting muscle is weak. If this is missed, the eyes can still look sleepy after a crease is created. Common signs are upper eyelids partly covering the pupils, raising your eyebrows to see clearly, and looking tired despite good rest. Our eye surgery page lists double eyelids with ptosis correction as the most popular combination, because it addresses the crease and muscle function together.

Canthoplasty changes the eye corners rather than the crease. It is considered when a fold covers the inner corner, when the outer corner is upturned, or when you want a wider, more open eye shape alongside double eyelid surgery.

Non-incisional ptosis correction uses local anaesthesia and sedation. It suits mild ptosis with thin eyelid skin and little fat. Incisional ptosis correction covers a wider range of drooping.

Canthoplasty is performed under sedation and comes in three types:

1. 01Epicanthoplasty opens the inner corner covered by the epicanthal fold.
2. 02Lateral canthoplasty lengthens or repositions the outer corner.
3. 03Lateral Hotz lowers the lower outer corner to increase vertical openness.

Our article on lengthening the gaze with canthoplasty explains the corner procedures further.

05Recovery after Korean double eyelid surgery: how long should you stay in Seoul?

Plan to stay in Seoul for at least 7-8 days after eye surgery. That allows time for post-operative check-ups, stitch removal and initial recovery before you fly. Your surgeon gives you the actual dates after the consultation.

What recovery usually looks like

After non-incisional surgery, stitches, if needed, come out earlier, after about 3-5 days.

After incisional surgery, a firm, sausage-like roll above the crease is typical through the first 1-2 weeks, and the fold looks higher than planned. Many people feel comfortable being seen in public by 2-4 weeks. Height usually settles nearer the plan by about 1-3 months, with softer definition continuing through roughly 3-6 months. Healing speed differs from person to person.

Avoid alcohol and smoking for a month after surgery. Alcohol may cause inflammation, and smoking contracts blood vessels and delays recovery.

A typical trip, day by day

1. 01Day 1: arrival, in-person consultation, examination and final plan. Bring any previous operation records.
2. 02Day 2: surgery, then rest at your accommodation. You are discharged the same day after double eyelid surgery.
3. 03Days 3-6: swelling checks. Most patients stay indoors for this stretch.
4. 04Day 7: stitch removal for procedures that need it.
5. 05After that: flight home once your surgeon clears you. Do not book a return flight before the plan is confirmed.

Surgery in Seoul vs at home

Under Korean law, only clinics registered with the Ministry of Health and Welfare may treat international patients, and the register is publicly searchable. It is worth checking before you book. If you notice fever, spreading redness, discharge, sudden pain or a change in vision after you return home, contact the clinic immediately and seek local care the same day.

06Eyelid revision: what if the crease is uneven or loosens?

Eyelid revision surgery corrects a crease that sits too high or too low, has loosened or is uneven. It also addresses scarring and difficulty closing the eye after earlier surgery. We examine what was done previously before making a new plan.

• Wait for healing. Most appearance concerns are judged after the scar has matured, often around six months after surgery. After several previous operations, waiting closer to a year can give a clearer surgical area.
• Some problems cannot wait. Earlier treatment may be needed if the eye cannot close, the eye surface is exposed or a stitch is causing injury.
• Expect a different approach. Revision often needs an incisional approach, even when the first surgery was non-incisional.
• Expect longer swelling. Scar tissue from previous surgery can make swelling last longer than after a first operation.

Revision takes about 1 hour under local anaesthesia and sedation. Stitches come out after about 5-7 days, and daily activities can resume in about 3-5 days. The realistic goal is clear improvement rather than identical eyelids, because previous scars, muscle strength and brow position limit what can change. Results vary between individuals.

Our article on revising upper eyelid surgery safely walks through the common revision cases.

07Summary

• Non-incisional: about 30 minutes under local anaesthesia, daily activities in about 3 days; suits thin eyelid skin that is not droopy.
• Incisional: about 30 minutes to 1 hour under local anaesthesia or sedation, stitches out after 5-7 days; suits thick, droopy or fatty eyelids.
• Combinations: ptosis correction is added when the lifting muscle is weak, and canthoplasty when the corners, not the crease, need changing.
• Stay: plan at least 7-8 days in Seoul, and book the return flight only after your surgeon confirms the plan.
• Revision: usually assessed around six months after the original surgery.

Send us one front photo and one side photo with your eyes open on WhatsApp, and tell us what you would like to change. We will suggest which method to discuss and how many days to plan. Anatomy and healing differ between individuals, so the final plan is confirmed when we examine you in Seoul.

Results and recovery differ from person to person. This article is general information, not a diagnosis — your surgeon confirms what suits you at consultation.
