매몰법 대 절개법 (maemolbeop dae jeolgaebeop — burial/suture method vs incision method) are the two primary surgical approaches for creating a double eyelid crease in Korea. Plastic surgery and dermatology collectively account for the largest share of procedures sought by international patients visiting Korea,¹ and double eyelid surgery is among the most frequently requested. The decision between these two techniques is anatomical, not preferential — getting it wrong is the most common driver of revision surgery.
Side-by-Side Comparison
Four variants exist within the broad non-incisional/incisional spectrum. Understanding where each sits on the permanence–recovery tradeoff helps clarify why surgeons match technique to anatomy rather than patient preference alone.
| Technique | Best eyelid type | Excess skin removal? | Ptosis correction? | Permanence | Suture loosening risk | Recovery time | Scar | Cost tier | Revision implications |
|---|---|---|---|---|---|---|---|---|---|
| Non-incisional (suture/burial) | Thin, no excess skin or fat | No | No | Not guaranteed — estimated 20–40% loosening within 5–10 years | Moderate–high on thicker lids; low on thin lids | Presentable 5–7 days; full 1–2 weeks | None | Lowest | Revision to incisional is common; two-procedure cost if revision needed |
| Partial incision | Moderate thickness, minimal excess skin | Minimal only | No | More durable than suture; less permanent than full incision | Low–moderate | 2–3 weeks | Minimal — short incisions fade to near-invisible | Low–mid | Revision possible; less scar tissue than full incision |
| Full incision | Moderate–thick lids, excess skin or fat | Yes | No (unless combined) | Permanent | Negligible | Stitch removal day 7–10; presentable 2–3 weeks; full 3–6 months | Fine line along crease — typically concealed within fold | Mid–high | Revision possible but scar tissue present; plan carefully at first procedure |
| Full incision + ptosis correction | Any thickness with drooping lid (levator muscle weakness) | Yes | Yes | Permanent | Negligible | Stitch removal day 7–10; full 3–6 months | Fine line along crease | Highest | Most complex revision scenario — choose technique precisely at initial surgery |
Non-incisional technique — small needle punctures pass sutures through the eyelid to create adhesion between skin and the deeper tarsal plate (the cartilage-like structure that gives the lid its structure). No tissue is removed. The absence of cutting is the source of its fast recovery and zero-scar advantage, but also the reason the result is reversible and subject to loosening over time.
Partial incision occupies middle ground: two or three short horizontal cuts allow minimal fat removal but stop short of the full skin resection possible with a complete incision. It suits patients whose eyelids are slightly too thick for pure suture technique but who do not have significant excess skin.
Full incision involves a continuous cut along the intended crease line, allowing the surgeon to remove a precise strip of skin and fat, reposition orbital fat if needed, and create the adhesion with direct tissue fixation. The result is anatomically permanent because the adhesion is created by scar tissue formation rather than sutures alone.
Full incision with ptosis correction adds levator aponeurosis advancement — repair or tightening of the muscle that lifts the lid — to the full incision procedure. Ptosis (drooping lid caused by a weakened or detached levator muscle) cannot be corrected by suture or skin removal alone. Attempting non-incisional technique on a patient with undiagnosed ptosis is a common error that produces an asymmetric, low-appearing crease even when the sutures hold.
Cost Comparison
Prices below reflect the Seoul Gangnam-gu market range for board-certified plastic surgeons as of July 2026.² FX rates: 1 USD ≈ ₩1,380; 1 AUD ≈ ₩900. Rates fluctuate — confirm current rates before financial planning. Quoted prices are surgeon and facility fees only; anesthesia, pre-operative testing, and post-operative care may be itemised separately.
| Technique | KRW range | USD range | AUD range | Additional cost if revision needed |
|---|---|---|---|---|
| Non-incisional (suture/burial) | ₩800K–2.5M | ≈$580–$1,810 | ≈AUD$890–$2,780 | +₩1.5M–4M (≈$1,085–$2,900 / AUD$1,670–$4,445) for incisional revision |
| Partial incision | ₩1M–3M | ≈$725–$2,175 | ≈AUD$1,110–$3,335 | +₩1.2M–3.5M for revision depending on complexity |
| Full incision | ₩1.5M–4M | ≈$1,085–$2,900 | ≈AUD$1,670–$4,445 | +₩2M–5M for revision — scar tissue increases complexity |
| Full incision + ptosis correction | ₩2.5M–6M | ≈$1,810–$4,350 | ≈AUD$2,780–$6,670 | +₩2.5M–6M+ for revision — most complex revision scenario |
The cost gap between non-incisional and full incisional is approximately ₩500K–1.5M (≈$360–$1,085 / ≈AUD$560–$1,670) at initial surgery. A patient who chooses non-incisional, experiences loosening, and then revisions to incisional technique effectively pays for two full procedures — a total outlay that typically exceeds the cost of choosing incisional at the outset. Gangnam-gu receives approximately 60% of medical tourists seeking aesthetic procedures in Korea,¹ and price competition in the district is high; the lowest quote is not always the safest benchmark.
Does Technique Choice Affect Surgeon Skill Requirement?
Both techniques require a board-certified plastic surgeon, but the skill demands differ in nature rather than magnitude.
KSPRS (대한성형외과학회, Daehan Seonghyeong Oegwa Haghoe — the Korean Society of Plastic and Reconstructive Surgeons) requires six years of medical school, a four-year plastic surgery residency, and successful board examinations before a surgeon can be certified.³ As of 2024, approximately 2,100 board-certified plastic surgeons are registered in Korea.⁴ KSPRS maintains a public registry where patients can verify certification by searching a surgeon’s name directly on the KSPRS website.⁵
For non-incisional technique, the primary skill is anatomical assessment — correctly identifying whether a patient’s eyelid thickness, fat volume, and skin laxity make them a suitable candidate. The surgical execution itself is technically less demanding than a full incision. However, an under-skilled assessment that places sutures in a patient with thick lids or excess skin produces an irregular crease and almost certain loosening. The technique penalises poor patient selection more than poor technical execution.
For full incision, the surgical execution is inherently more demanding: the surgeon must plan and execute a symmetric crease excision on both eyes simultaneously, control bleeding, manage orbital fat precisely, and close with fine sutures that will scar inconspicuously within the crease line. An asymmetric excision or excessively high crease placement creates a result that is difficult to revise without additional scarring. Full incision with ptosis correction adds a layer of complexity — the levator aponeurosis must be advanced by a precisely calculated amount, as over-correction produces an unnaturally wide-eyed appearance and under-correction leaves the ptosis unresolved.
The practical implication for patients: do not select non-incisional on the assumption that it is a simpler, lower-stakes procedure. The assessment phase is the critical competency. Verify your surgeon’s KSPRS board certification⁵ regardless of which technique is recommended, and ask specifically how many eyelid procedures the surgeon performs per month. KSPRS board certification is legally required to perform plastic surgery in licensed facilities in Korea.⁶
Decision Framework: Choose Suture If / Choose Incisional If
| Patient situation | Recommended technique | Rationale |
|---|---|---|
| Thin eyelids, no excess skin, no ptosis | Non-incisional (suture/burial) | Ideal candidate profile — low loosening risk, fast recovery, no scar. Suture technique can create a natural crease without tissue removal. |
| Moderate eyelid thickness, no significant skin excess | Partial incision or non-incisional after assessment | Borderline case — surgeon assessment of fat volume determines whether minimal incision is needed. Do not default to suture without assessment. |
| Thick eyelids or hooded/excess skin | Full incision | Suture technique on thick lids has high loosening risk and produces an irregular crease. Incisional is the appropriate first-choice technique. |
| Drooping lid (ptosis) present | Full incision + ptosis correction | Ptosis cannot be addressed without accessing the levator aponeurosis — requires full incision. Non-incisional on a ptotic lid will produce asymmetry even if sutures hold. |
| Want fastest recovery, accept non-permanence | Non-incisional — only if anatomy is appropriate | Recovery advantage is real but only valid if anatomy supports the technique. Choosing suture for speed on unsuitable anatomy leads to revision and longer total downtime. |
| Want permanent result, no revision | Full incision | Incisional creates permanent adhesion via scar tissue. If permanence is the primary goal, incisional is the definitive choice regardless of recovery timeline. |
| Anticipate wanting revision or adjustment later | Non-incisional (suture/burial) | Suture results are reversible and revisable with less scar burden than revising a full incision. Patients uncertain about crease height or style may prefer this flexibility — with the understanding that revision will eventually be incisional for a permanent result. |
| Revision of prior non-incisional surgery | Full incision | Revision should address accumulated suture scar tissue, reset crease height, and create a permanent result. Non-incisional revision of non-incisional is rarely definitive. |
Three factors override patient preference in every case: eyelid thickness, presence of excess skin, and presence of ptosis. If any one of these three factors is present, full incision is the clinically indicated technique. The suture method is not a universally gentler or safer option — it is the correct option for a specific anatomical profile. Patients who arrive in Korea having decided on suture technique based on shorter recovery time should expect a competent surgeon to challenge that preference if their anatomy does not support it.
Can I switch from non-incisional to incisional double eyelid later?
Yes — revision from non-incisional to incisional is one of the most common eyelid surgery revisions in Korea. Loosened or unsatisfactory suture results can be revised to incisional technique, typically after a 6–12 month waiting period from the original procedure. The revision can adjust crease height, remove accumulated scar tissue from the sutures, and achieve a permanent result. This two-procedure pathway costs significantly more than choosing incisional initially.
Which double eyelid technique has less swelling?
Non-incisional technique produces substantially less swelling — most patients are presentable within 5–7 days. Incisional technique involves tissue resection and repositioning that creates more surgical trauma, with swelling peaking at day 2–3 and substantially resolving over 2–3 weeks. The tradeoff is permanence and the ability to address skin excess and ptosis simultaneously.
Is the suture method (non-incisional) weaker?
The non-incisional crease holds well immediately post-operatively. The concern is longevity: sutures can loosen gradually over years, particularly in patients with thicker or heavier eyelid tissue. An estimated 20–40% of non-incisional patients experience some degree of loosening within 5–10 years. Patients with thin eyelids who are good candidates for the technique have significantly lower loosening rates.
Does the choice of technique affect how natural the result looks?
Both techniques can produce natural-looking results on appropriate candidates. The most common cause of an unnatural result is technique–anatomy mismatch — non-incisional on thicker eyelids produces an irregular crease; incisional with an excessively high crease placement does not suit Asian facial anatomy. Korean surgeons typically use crease heights of 4–6mm for natural-looking results in Asian anatomy.
