Double-eyelid surgery (blepharoplasty) is the single most-performed cosmetic procedure in Korea — and one of the most misunderstood by international patients. Three different techniques sit under the same name, and the right choice depends on your eyelid anatomy, not the clinic's marketing.
This guide walks through the three methods, what each can and cannot do, and how ptosis correction fits in.
The three techniques at a glance
- Non-incisional (suture method) — fine sutures pass through small puncture points along the desired crease line. No skin is cut.
- Partial-incisional — a 10–15 mm incision in the central eyelid permits limited fat removal while keeping the lateral eyelid untouched.
- Incisional — a full-length incision along the desired crease allows precise removal of skin, fat, and muscle, plus internal fixation of the new fold.
1. Non-incisional double-eyelid surgery
Best for thin-skinned, young patients with minimal excess fat or skin and no significant ptosis. The surgeon creates the crease using buried sutures that anchor the eyelid skin to the underlying levator aponeurosis.
- Surgery time: 20–40 minutes.
- Recovery: visible swelling subsides in 5–7 days; most international patients can fly home within a week.
- Pros: minimal scarring, fast recovery, technically reversible (sutures can be removed within a few weeks if the result is unsatisfactory).
- Cons: higher long-term loosening rate. Roughly 5–15% of cases lose the crease over years and need revision.
2. Partial-incisional double-eyelid surgery
A practical middle path. The incision is short enough to leave only a faint scar in the natural crease, but long enough to allow controlled fat reduction and modest skin adjustment.
- Best for: patients with moderately puffy upper lids who do not need significant skin removal.
- Recovery: 7–10 days for the most visible swelling to settle. Sutures usually removed at day 5–7.
- Pros: more durable than non-incisional, less invasive than full incisional.
- Cons: not appropriate for heavy excess skin; central scar may be slightly visible if scarring is unfavorable.
3. Incisional double-eyelid surgery
The most powerful and most permanent technique. A full-length incision allows the surgeon to remove redundant skin and orbicularis muscle, sculpt fat pads, and secure the crease with internal fixation sutures that resist long-term loosening.
- Best for: thick eyelid skin, significant fat, asymmetric eyes, revision cases, and patients combining ptosis correction or epicanthoplasty.
- Recovery: sutures out at day 7; visible swelling for 2–3 weeks; final crease shape stabilizes around 3–6 months.
- Pros: precise, durable, addresses every component of eyelid anatomy.
- Cons: longer downtime, faint scar along the crease (usually invisible once the eye is open).
When you also need ptosis correction
Ptosis is a weak levator muscle that lets the upper lid sit too low, producing a sleepy or heavy-eyed appearance. Roughly four in ten Korean double-eyelid patients have some degree of ptosis, and adding correction at the same time produces a brighter, more alert outcome.
Ptosis correction must be done through an incisional or partial-incisional approach — non-incisional surgery cannot address the levator muscle. If a clinic markets "non-incisional with ptosis correction" without examining your levator function, ask for clarification before booking.
How to read your consultation
A thorough surgeon will examine:
- Skin thickness and laxity (skin pinch test).
- Pre-aponeurotic fat volume.
- Levator function — measured in millimeters of upper-lid excursion.
- Symmetry of margin reflex distance (MRD1) between the two eyes.
- Whether epicanthoplasty (medial-corner widening) or lateral canthoplasty would be helpful.
If the consultation skips these and goes straight to recommending a technique, you have not had a real consultation — you have had a sales pitch.
Choosing between the three
A simple decision tree most surgeons would agree with:
- Thin lids, no ptosis, want a reversible option → non-incisional.
- Some fat to remove, but skin is fine → partial-incisional.
- Excess skin, ptosis, asymmetry, or revision → incisional, with ptosis correction if indicated.
Cost ranges in Gangnam (2026)
- Non-incisional: USD 800–1,500.
- Partial-incisional: USD 1,200–2,000.
- Incisional with ptosis correction: USD 1,800–3,500.
Pricing varies with surgeon experience, clinic district, and whether epicanthoplasty is added. Always ask for an itemized written quote.
The technique is a tool. A skilled surgeon will pick the smallest tool that solves your eyelid's specific problem, not the most lucrative one. Walk in knowing the differences and you will get a better consultation.
