Turning a monolid into a defined double eyelid can be done in more than one way, and the right method depends on your eyelid — its skin thickness, the amount of fat, and whether the eye-opening muscle is a little weak. A light buried-suture technique suits some eyes; a full incision suits others; and where ptosis is present, correcting the muscle can be part of the plan. This page explains how the methods differ and how a consultation decides which fits you.
Garnet is well known for neck-wrinkle and lifting surgery. The facility is excellent and I’m thoroughly satisfied with the friendly consultation and the surgeon’s skill.
Director Baek In-soo, thank you so much. Thanks to you I keep getting told I look younger — it feels like I’ve gone back to my younger days.
I had upper and lower eyelid surgery and I’m really satisfied. The director and the manager were both so kind and clear.
I started with under-eye fat repositioning — the director and the manager are genuinely kind and good at what they do. I’ll be back.
I came on a referral and was very satisfied thanks to the doctor’s kind consultation and clear explanations. The nurses were friendly too.
I kept reading the reviews and came trusting the many mentions of skill and kindness. The clinic was busy with patients and spotless.
A double eyelid is simply a fold in the upper lid: when you open your eye, the skin above the lashes tucks in and forms a crease. A monolid does not have this fold, or has a very faint one. Creating a crease surgically means forming a fixed connection between the skin and the underlying lid structures so that, as the eye opens, the fold appears in a consistent place. That connection can be made in two broad ways — with fine buried sutures, or through a full incision — and each produces the fold by a slightly different mechanism.
Neither method is universally “better.” They suit different eyelids, and the choice hinges on the thickness of your skin, how much fat sits in the lid, how firm the tissues are, and how defined and durable you want the crease to be. There is also a third factor that is easy to miss: whether the muscle that opens the eye is a little weak, which changes the plan.
The three routes below — the non-incision (buried-suture) method, the incision method, and ptosis correction where the muscle is weak — cover how a monolid is turned into a defined crease, and understanding them makes a consultation much easier to follow.
The non-incision method creates the fold without cutting the lid open. Fine sutures are buried through the eyelid to form a fixed adhesion line, and that line becomes the crease as the eye opens. Because there is no long incision, the swelling tends to be lighter and the recovery quicker, and at Garnet the sutures are removed at around five days. It is often chosen by younger patients and by those who want a softer, more natural-looking fold.
Its appeal is speed and subtlety, but it has honest limits. It works best on thinner lids with limited fat and good skin elasticity; on thick, fatty or heavier lids the buried sutures have more to hold and the crease may be less crisp or less durable over time. It also does not remove skin or fat, so it is not the tool for a lid that needs debulking.
For the right eyelid it is an elegant option; for the wrong one it can be a crease that fades or loosens. That is precisely why the method is chosen against your anatomy rather than by preference alone.
The incision method creates the fold through a full incision along the intended crease line, which lets the surgeon adjust or remove a little skin and fat and form a firm, well-defined crease that tends to be more durable. At Garnet it is a full upper-lid incision with sutures removed at around seven days. It is the usual choice for thicker or fattier lids, for lids where skin needs tidying, and for patients who want a clearly defined, lasting fold.
The trade-off compared with the buried-suture method is a slightly longer recovery and, because there is a genuine incision, a fine line along the crease. That line is placed within the fold, so once healed it typically settles into the crease and becomes difficult to see. Because the technique can also address fat and skin, it handles eyelids the non-incision method cannot.
Notably, the incision method also allows ptosis correction to be added in the same operation if the eye-opening muscle is weak — which is a common reason it is chosen over the buried-suture route.
Many people who want a double eyelid also have a degree of ptosis — the muscle that opens the eye is a little weak, so the lid margin sits low and the eye looks sleepy. If you create a crease but leave that weakness untreated, the eye can still look half-closed even with a lovely new fold, and the two eyes may look uneven. In these cases ptosis correction — adjusting the strength of the eye-opening muscle through the same crease incision — is combined with the double-eyelid surgery so the eye both gains a fold and opens more fully.
This is one of the most important reasons an assessment matters before choosing a method. A person may ask simply for a crease, when the more complete answer is a crease plus a small muscle adjustment. Because ptosis correction is done through an incision, it naturally pairs with the incision double-eyelid method rather than the buried-suture one.
Not everyone with a monolid has ptosis, and adding muscle work when it is not needed is over-treatment. The consultation exists to work out whether your eye needs only a fold, or a fold and a muscle adjustment together.
The choice comes down to your anatomy: thin lids with limited fat, firm skin and no muscle weakness often do beautifully with the light non-incision method; thicker or fattier lids, lids needing a little skin or fat adjusted, or patients wanting a firmly defined and durable fold generally suit the incision method; and where the eye-opening muscle is weak, ptosis correction is added. It is not a matter of one method being superior — it is a matter of fit.
This is a hands-on judgement about skin thickness, fat volume, tissue firmness and muscle strength, and it is not something you can settle from a photo or a trend. An honest surgeon will sometimes steer you away from the method you arrived asking for, because your eyelid would hold a better, longer-lasting result with the other one. A crease height and shape that suit your face are also part of the discussion — a natural, in-fold crease reads very differently from a high, dramatic one.
A candid consultation — including telling you a subtle, natural fold is likely to suit you better than a bold one — is a good sign, not a limitation.
Garnet is a single-surgeon clinic in Apgujeong, Seoul. Dr. In-Soo Baek is a board-certified plastic surgeon (Korean medical licence no. 77407) who examines your lid thickness, fat, skin and eye-opening muscle, then recommends the buried-suture method, the incision method, or an incision with ptosis correction depending on what your eyelid actually needs — and discusses a crease height that suits your face rather than a trend. The same surgeon who assesses you performs the surgery and reviews you at follow-up, so the plan and the result stay consistent.
With the schedule capped at two surgeries a day, the consultation is unhurried, and the aim is a natural-looking crease that reads as your own eye. Garnet is registered with Korea's foreign-patient programme, so you can begin with an online consultation: send photos of your eyes open and closed, describe the look you have in mind, and get an honest view of which method is likely to suit you before you plan any travel.
Send photos and your question before you travel. An English-speaking coordinator reviews every enquiry and replies with honest guidance on whether surgery is appropriate, the likely plan and timing.
