Scarless eye bag surgery? Transconjunctival lower blepharoplasty explained
Eye bag surgery through the inside of the lower lid leaves no cut on the skin. It suits bulging fat with little loose skin, and it is a route, not a separate kind of result. Marketing names such as "4D" are not medical terms.

- Transconjunctival lower blepharoplasty reaches the fat pads through the lining inside the lower lid, so there is no incision on the skin.
- It suits fat that bulges forward with little excess skin, and a second cut under the lashes is needed if skin must be trimmed.
- The fat can be removed or repositioned into the groove below the bag, and recent practice leans toward preserving volume.
- Case series of 110 and 232 patients report improvement of the groove with mostly temporary problems, but follow-up is short and techniques are not ranked against each other.
- Names like "4D eye bag removal" are clinic marketing labels, so ask for the approach, the fat plan, the skin plan and the lid support in plain words.
Transconjunctival lower blepharoplasty is eye bag surgery done through the inside of the lower eyelid, so there is no cut on the skin. The surgeon reaches the fat pads behind the lid, then removes some of the fat or moves it into the groove below. It suits bulging fat with little loose skin. It is not a different kind of result from other methods, only a different way in, and it still carries the risks of any lower lid operation.
What is transconjunctival lower blepharoplasty?
It is a lower eyelid operation in which the incision is made on the conjunctiva, the thin pink lining inside the lid, instead of on the skin under the lashes. Blepharoplasty is the medical word for eyelid surgery, and "trans" and "conjunctival" simply say through the conjunctiva. The NHS describes the two routes for lower lid surgery in plain terms: an incision either just below the lower lashes or on the inside of the lower eyelid, followed by repositioning or removing fat from the bags and sometimes a small amount of skin.
A 2025 review of the technique states why surgeons value the inside route. The lower eyelid is held up in part by the orbicularis, the ring of muscle around the eye, and the transconjunctival approach offers the potential to preserve that support. That preservation potentially lowers the risk of complications such as lower eyelid retraction (the lid pulled down so that white shows below the iris) and ectropion (the lid turning outwards). The same review says the approach can be used across a wide spectrum of cosmetic and functional indications, so it is a route, not a single operation.
Is "4D eye bag removal" a medical term?
No. Names such as "4D", "3D" or similar numbered and branded labels on eye bag surgery are marketing names that a clinic chooses, and they are not defined medical terms. Two clinics using the same label can be doing different things, and one clinic can describe the same operation under two names. The studies cited on this page describe techniques by what is actually done: the approach, what happens to the fat, whether a ligament is released, and whether skin is removed.
That is the useful way to compare. When you meet a marketing name, ask for the plain description of the operation. The questions to put are:
- Is the cut inside the lid or on the skin?
- Is fat removed, moved, or both?
- Is any ligament released to soften the groove under the bag?
- Is skin removed or treated, and how?
- Is the outer corner of the lid supported?
- Which anaesthetic is planned?
The answers describe the operation. The label does not. For how these answers shape a quotation, see what decides the fee for eye bag surgery in Malaysia.
Who suits the inside-the-lid approach?
It suits a bag that is mostly fat bulging forward, with only a little loose skin. An American review of blepharoplasty notes that the transconjunctival route is used to address herniated fat pads and can be combined with release of the orbitomalar ligament and added volume, by moving fat or by filler, to blend the lid into the cheek. A 2019 series of 110 patients on a modified fat-repositioning technique concluded it improved a tear trough deformity (the groove under the eye) without severe orbital skin laxity, which is the same message from another angle: lots of excess skin is a reason to think again about the plan.
A bag that sits lower on the cheek, or swelling that comes and goes, may not be a simple fat pad at all. The article on festoons and malar mounds explains that group, and the guide to lower blepharoplasty separates fat from fatigue and from other causes. A surgeon also checks how firm the lower lid is before choosing any route, because lid malposition is one of the more serious complications of lower lid surgery.
Is the fat removed or repositioned?
Either can be done through the inside of the lid, and the choice depends on the shape of the eye bag and the groove beneath it. Removal takes out the bulging fat. Repositioning keeps the fat, releases the ligament that holds the groove, and spreads the fat into the hollow so the bag and the groove blend.
The wider trend is toward preserving volume. The American review observes that recent practice in both upper and lower lid surgery has moved toward volume preservation and, at times, adding volume, with the aim of avoiding a hollow look. A 2023 series of 232 patients on fat repositioning is a good example of the debate. It asked whether a lot of herniated fat is needed at all, and found that in people with minimal or no excess fat herniation the groove was improved, provided a fat pad could be felt. In that series, more than 85% of tear trough deformities were eliminated, and the share of patients rating their deformity as moderately to extremely severe fell from 86.3% before surgery to 34.0% afterwards. Treat these as the results of one centre, in a study its authors class as level IV evidence, which means there was no comparison group.
What do studies report about results and risks?
They report good short-term results with a low rate of problems, but the evidence is mostly case series with short follow-up, and it does not rank one technique above another. In the 110-patient series, the tear trough improved in 97.73%, the remaining 2.27% had a revision, and the complications were three local depressions and one local bulge, treated with surgical refinement, plus one bleed that settled with electrocautery. In the 232-patient series the recorded complications were 12 cases of temporary conjunctival bleeding, two of eyelid numbness and six of dry eye, and all resolved without treatment.
A systematic review of 36 articles concluded that lower blepharoplasty has a low overall complication profile, that no major complications causing visual problems were reported, and that most functional and aesthetic problems resolved with conservative management or a revision. It also said more rigorous studies are needed to compare techniques. A caution is built in: the same surgeons who report these numbers are describing their own patients, so the figures show what is possible in experienced hands, not what every operation will deliver.
The NHS lists the rarer serious risks of eyelid surgery in general: bleeding into the eye socket, impaired vision and ectropion, along with asymmetry, scarring and temporary blurred or double vision. Dry eye can follow, and the article on dry eye after eyelid surgery explains why. A lid that turns outwards is covered in the article on ectropion.
What is recovery like, and is it really scarless?
"Scarless" is shorthand for no cut on the skin, and it is fair in that narrow sense. An incision on the inside of the lid is not on the visible surface, but surgery still causes swelling, bruising and healing, and the lid and the conjunctiva still heal for weeks. The NHS says most people take about two weeks off work after eyelid surgery, that bruising and redness can take several weeks to fade, and that eyes may feel irritated or watery for a few weeks. The week-by-week picture is in the lower blepharoplasty recovery article.
If skin also needs trimming, a second cut under the lashes is usually needed, which changes the "no skin cut" description. Ask whether that is part of your plan. Dr Catherine Chow begins consulting at Eagle Eye Centre Malaysia, Petaling Jaya, from early 2027, so this page explains the approach in general and does not describe a service at present.
Whoever you choose, check the surgeon's registration with the Malaysian Medical Council and ask about training in eyelid surgery and about follow-up if something goes wrong. For the wider list of questions before any operation, see the aesthetics section, and my hub article on why eyes look tired.
- A bag sits low on the cheek, or the swelling comes and goes, which may not be a simple fat pad.
- The lower lid already looks loose, pulled down or turned outwards.
- You are offered a branded or numbered eye bag procedure without a plain description of what is done.
- After any lower eyelid surgery you have severe pain, a sudden change in vision or one eye much more swollen than the other, which needs urgent attention.
Questions patients ask
It is lower eyelid surgery through an incision on the conjunctiva, the lining inside the lid, instead of on the skin under the lashes. The surgeon removes or repositions fat from the eye bags through that opening.
It leaves no cut on the visible skin, which is what scarless means here. It still involves swelling, bruising and healing, and if skin also needs trimming a second cut under the lashes is usually needed.
It is a marketing name that a clinic chooses, not a defined medical term, so it can mean different things at different places. Ask for the plain description: the approach, whether fat is removed or moved, any ligament release, and whether skin is removed.
People whose bags are mostly fat bulging forward, with little excess skin. A series of 110 patients concluded the modified fat-repositioning technique suits a tear trough without severe skin laxity. A surgeon decides after examining the lid.
Either can be done through the inside of the lid. Removal takes out the bulging fat. Repositioning moves it into the groove under the bag, often after releasing the ligament that holds the groove, and recent practice leans toward preserving volume.
The NHS lists asymmetry, scarring, temporary blurred or double vision, and rarely ectropion, bleeding into the eye socket and visual impairment. In the series cited here, temporary conjunctival bleeding, numbness and dry eye were recorded.

Lower eyelid surgery and eye bags: when it is fat, not fatigue
A photograph from ten years ago, and the question of what cream will take eye bags back to that face, is a familiar one. The honest answer is none, because what is showing is not fatigue. It is fat, sitting in the wrong place.
