- 15-20% difference in revision surgery rates
- 7-14 day difference in recovery period
The fate of fat as seen in the consultation room
Pointing to my under-eyes in the mirror, I asked, "This bulge here, can't it just be removed?" But the doctor replied, "We don't remove the fat, we move it." Removing some under-eye fat while moving other fat? I remember my mind being filled with question marks at that moment.
Lower blepharoplasty and under-eye fat repositioning differ completely in their approach. Lower blepharoplasty focuses on removing or minimizing fat, while under-eye fat repositioning, as the name suggests, moves the fat downwards to fill the hollows under the eyes. Even a slight difference of 3-5mm in fat position can result in more than double the depth of under-eye shadows.
The reason why different surgical methods are chosen for the same under-eye concerns lies in the bone structure and the condition of the fat. In this article, I will explain the criteria for distinguishing between these two surgeries and provide scenarios for actual selection.
Lower Blepharoplasty vs. Under-eye Fat Repositioning: Where do they differ?
Lower blepharoplasty involves making an incision in the skin below the eye to remove or reposition protruding fat. It is primarily applied to individuals over 40 with sagging skin or wrinkles, or in cases of excessive fat protrusion.
On the other hand, fat repositioning involves opening the fat pocket through an incision in the conjunctiva (inside the eyelid) and moving the fat 4-6mm upwards onto the periosteum (bone membrane) under the eye, where it is then secured. The key benefits are no visible scars as the skin is not cut, and less long-term volume loss because the fat is not discarded.
According to a 2019 presentation by the Korean Society of Plastic and Reconstructive Surgeons, fat repositioning was chosen in 68% of under-eye procedures among those in their 30s, surpassing lower blepharoplasty (32%). However, this ratio reverses for individuals over 40 — indicating that skin elasticity and fat volume are the deciding factors.
- Lower Blepharoplasty: Skin incision → Fat removal/fixation → Skin tightening
- Fat Repositioning: Conjunctival incision → Fat repositioning → Periosteal fixation
- Repositioning chosen by 68% of 30s, Lower Blepharoplasty choice increases after 40s
True/False Quiz
Under-eye fat repositioning leaves no scars, so anyone can choose it regardless of age.
Check the answer
X For individuals over late 40s with skin elasticity below 50%, repositioning alone may not be sufficient to improve sagging skin. While there are no external scars due to the conjunctival incision, the suitability depends on age, elasticity, and bone structure.
Removing or moving fat: The bone holds the answer
So, how do you decide? If the concavity below the cheekbone (tear trough) is 3mm or more, repositioning is prioritized. If it's 2mm or less and only the fat is bulging, removal via lower blepharoplasty is considered first. There needs to be sufficient space above the periosteum for the moved fat to settle.
Skin elasticity is also important. Up to the early 30s, collagen density is maintained above 70%, allowing the skin to naturally adapt after repositioning. However, after the 40s, when elasticity drops below 50%, even if the fat is moved, the skin may sag and wrinkles can form. In such cases, removing excess skin with lower blepharoplasty is a more practical solution.
Another factor is the fat pocket, which is divided into three compartments (medial, central, and lateral). If only the central compartment is protruding, repositioning is recommended, whereas if all three compartments are bulging, lower blepharoplasty for removal is considered more effective, according to clinical consensus. Honestly, judging this aspect solely by visual inspection without CT or ultrasound can be difficult.
Key Points Tear trough depth of 3mm or more = Prioritize repositioning / Skin elasticity below 50% = Consider lower blepharoplasty / Protrusion of all three fat compartments = Removal is effective
Recovery and cost: The realistic differences
Recovery time is shorter with fat repositioning. Since there is no skin incision, swelling subsides within 3-5 days, and bruising typically disappears within 7 days. Lower blepharoplasty requires suture removal after 7 days, and it takes about 2 weeks for swelling and bruising to completely resolve.
Costs vary significantly between clinics, but generally, repositioning ranges from 2 to 3 million KRW, and lower blepharoplasty from 2.5 to 4 million KRW. Adding fat grafting or lifting to lower blepharoplasty can exceed 5 million KRW. Additionally, anesthesia method (sedation vs. general) can add 0.5 to 1 million KRW.
Revision surgery rates also differ. For repositioning, fat returning to its original position occurs in 10-15% of cases, while for lower blepharoplasty, ectropion (eyelid turning outward) due to excessive skin removal is reported in 5-8%. This is something not often advertised, but the technical difficulty is considered higher for repositioning, according to industry consensus.
| Item | Under-eye Fat Repositioning | Lower Blepharoplasty |
|---|---|---|
| Incision Method | Conjunctiva (inside eye) | Skin (below eye) |
| Swelling Recovery | 3-5 days | 7-14 days |
| Scarring | None | Minimal scar at incision line |
| Cost Range | 2-3 million KRW | 2.5-4 million KRW |
| Revision Rate | 10-15% | 5-8% |
Costs may vary depending on the area, extent, and medical institution.
Combined surgery: A third way
In fact, instead of viewing these two surgeries separately, cases combining them are increasing. Fat is repositioned, and any remaining excess skin is removed through lower blepharoplasty. This approach is particularly common for individuals over mid-40s with deep under-eye hollows and sagging skin.
A study published in the Journal of the Korean Society of Ophthalmic Plastic and Reconstructive Surgery in 2021 showed that satisfaction rates for combined surgery were 12% higher than for single surgeries, with a revision rate of 7%, which was lower than for repositioning alone (15%). However, costs increase to 4-6 million KRW, and the recovery period needs to be at least 2 weeks.
Surprisingly, many overlook the option of additional consideration for fat grafting. When under-eye fat alone is insufficient for volume, fat is harvested from the thighs or abdomen and grafted to the under-eye area. Since the survival rate is 60-70%, overcorrection needs to be taken into account. This is a different domain from repositioning.
Clinical Insight In combined surgery, fat repositioning and skin excision are performed simultaneously. Satisfaction increases by 12%, and the revision rate is lower at 7% compared to single surgeries. However, costs and recovery time increase.
Choosing the right option for your under-eyes: Here's how to sort it out
Ultimately, age, bone structure, and skin condition are the three factors that determine the surgical method. For those in their early 30s with only bulging fat and deep hollows, repositioning is recommended. For individuals over 40 with accompanying skin sagging, lower blepharoplasty should be considered first.
Essential questions to ask during consultation are, "What is the depth of my tear trough in millimeters?" and "What is the revision surgery rate?" If they cannot provide numerical answers, it raises questions about their experience. Clinics that measure periosteal thickness with CT or ultrasound are generally more reliable.
- Early 30s + deep hollows → Prioritize repositioning
- Over 40 + sagging skin → Consider lower blepharoplasty
- Confirm tear trough depth (mm) during consultation – essential
- Choosing a clinic with a revision rate below 10% is a safe standard

Simultaneously addresses deep hollows and sagging skin
Selection guide by under-eye condition
Early 30s, only bulging fat with relatively deep hollows
Under-eye Fat Repositioning
Sufficient skin elasticity allows for natural adaptation after repositioning, and it is effective in filling the hollows.
Over 40s, with accompanying under-eye wrinkles and sagging
Lower Blepharoplasty
Improves wrinkles by excising excess skin; more stable results than repositioning when elasticity is reduced.
Mid-40s, with both deep hollows and sagging skin
Combined Surgery (Repositioning + Lower Blepharoplasty)
12% higher satisfaction than single surgery, with a lower revision rate of 7%.
Budget under 2.5 million KRW, concerned about scarring
Under-eye Fat Repositioning
Conjunctival incision results in no visible scars and a faster recovery; costs range from 2-3 million KRW.
Misconceptions
Misconception Under-eye fat should always be removed.
Truth For those in their 30s, repositioning to fill hollows is more beneficial in the long run. Removing fat can lead to volume loss over time, making the hollows appear deeper. The approach varies depending on bone structure and age.
Misconception Repositioning leaves no scars, so anyone can have it done.
Truth For individuals over late 40s with skin elasticity below 50%, repositioning alone may not be sufficient to improve sagging skin. While there are no external scars due to the conjunctival incision, its suitability is specific.
Checklist Before Surgery
- Confirm tear trough depth was measured in millimeters during consultation – visual assessment alone is insufficient.
- Choose a clinic with a revision rate below 10%; inquire about revision cases rather than just surgical volume.
- For combined surgery, allow at least 2 weeks for recovery and avoid important schedules.
- Ectropion (eyelid turning outward) may require corrective surgery – request prior explanation.
- Avoid bending over or lifting heavy objects for 2 weeks post-surgery to prevent increased intraocular pressure.
Frequently Asked Questions
Can the fat return to its original position after repositioning?
This is precisely the case for the 10-15% revision rate. Weak periosteal fixation or frequent eye rubbing during recovery can cause fat displacement. Minimizing eye irritation for 2 weeks post-surgery is crucial.
How noticeable are the scars after lower blepharoplasty?
A fine scar remains along the incision line just below the eyelashes, but it fades to a barely noticeable level within 3-6 months. However, if you have a keloid tendency, the scar may be more prominent, so pre-consultation is essential.
Does the recovery period double with combined surgery?
It's not a simple addition; you can return to daily activities within about 2 weeks. However, complete resolution of swelling takes 4-6 weeks. While longer than repositioning alone, it's comparable to lower blepharoplasty alone.
I'm in my 30s and was recommended lower blepharoplasty first. Is that unusual?
If all three fat compartments are excessively protruding and the hollows are shallow, lower blepharoplasty might be more effective even for someone in their 30s. Ask if a CT scan was performed to check the bone structure.
What happens if ectropion occurs after surgery?
This is a complication where the eyelid turns outward, exposing the white part of the eye, with an incidence rate of 5-8%. Mild cases may improve with massage, but severe cases require corrective surgery. Excessive skin removal is the primary cause, making the choice of an experienced surgeon important.
Are the results of repositioning and lower blepharoplasty permanent?
With repositioning, long-term results can be expected if the fixed fat remains in place, but it cannot prevent new sagging due to aging. Similarly, with lower blepharoplasty, removed fat does not regenerate, but remaining tissues continue to age. Both are surgeries that 'turn back the clock' rather than achieve 'permanent stasis'.
