Quick answer: Under-eye fat repositioning moves bulging fat from the eye bag down into the hollow below it (the tear trough), smoothing the lid-cheek junction rather than just removing fat. It works well for shadow-type dark circles caused by bags and hollows, but not for pigmented or vascular dark circles. Visible swelling usually lasts one to two weeks, so plan about a week in Seoul.
What causes eye bags and dark circles?
Under-eye concerns have several different causes, and the right treatment depends on which applies to you:
- Fat herniation: the membrane holding fat around the eye weakens, so fat bulges forward as a bag.
- Tear trough hollow: a groove below the bag, from thin tissue and ligament attachments, creates a shadow.
- Pigmentation: brown discoloration of the skin, common in darker skin types.
- Vascular or thin skin: bluish or purple tones from visible vessels and muscle.
- Skin laxity: loose, crepey skin and fine wrinkles.
Fat repositioning addresses the first two. Pigment and vascular darkness generally need skin treatments such as lasers, topical care or, in some cases, filler or fat to thicken the area. A good consultation separates these causes before recommending surgery.
How does under-eye fat repositioning work?
Instead of only cutting fat away, the surgeon releases the tissue tethering the tear trough and drapes or secures the herniated fat into the hollow. The goal is a smooth transition from lower lid to cheek. Removing too much fat can leave a hollow, tired look over time, which is why repositioning (sometimes with limited removal) has become a common approach.
Inside or outside incision: which approach?
- Transconjunctival (inside the lid): no visible scar, faster recovery and less risk of lid shape change. Suited to people with bags but little excess skin, often younger patients.
- Subciliary (just below the lashes): allows removal of excess skin and tightening of the muscle as well. Suited to older patients with loose skin, but carries more risk of lid position changes.
Some clinics combine an inside approach with a skin pinch or laser resurfacing to tackle mild skin laxity without an external muscle incision.
Who is a good candidate?
- Visible bags and a shadowed groove that are present even when well rested
- Adults in good health with no active eye infection or severe dry eye
- Those whose main concern is contour, not skin color
Less suitable cases include primarily pigmented dark circles, fluid-related puffiness that changes from day to day (which may relate to allergies, sleep or kidney or thyroid issues worth checking), and lids with marked laxity at risk of pulling down after surgery.
What is recovery like?
- Days 1-3: swelling and bruising, sometimes a little bleeding into the white of the eye. Sleep with your head raised and use cold compresses as instructed.
- Days 5-7: stitches removed if an outer incision was used. Many people go out with sunglasses.
- Weeks 2-3: most bruising resolves; makeup is usually allowed after the surgeon checks healing.
- Months 1-3: firmness and small irregularities soften as the result settles.
Seven days in Seoul usually covers the procedure and first checks; ten days gives more margin. See our
first visit guide for planning tips.
What are the risks?
- Residual bulge or new hollowing if fat is under- or over-treated
- Lumps or irregularities from repositioned fat
- Lower lid pulling down (ectropion or scleral show), more associated with external incisions
- Dry eye, chemosis (swelling of the eye surface) and temporary blurred vision
- Bleeding behind the eye, rare but serious; sudden pain, pressure or vision changes need emergency care (119 in Korea)
How does it compare with filler for tear troughs?
Hyaluronic acid filler can soften a mild hollow with no downtime but does not remove a bag, and in some people it causes puffiness or a bluish tint. Fat repositioning tackles the bag and hollow together, with longer-lasting results. Fillers remain useful for mild cases or for fine-tuning after surgery. If you have had filler under the eyes before, tell the surgeon, since residual product can affect planning and may need to be dissolved first.
Choosing a clinic in Gangnam
Both plastic surgeons and oculoplastic ophthalmologists perform this operation. Ask how they assess lid laxity, which approach they recommend and why, and how they manage dark circles that surgery will not fix. You can browse
plastic surgery and
dermatology clinics for surgical and skin-based options.
Frequently asked questions
Will my dark circles disappear completely?
Shadows from bags and hollows usually improve noticeably. Brown or bluish discoloration of the skin often remains and may need separate treatment.
How long do results last?
Results are generally long-lasting, though natural aging continues. Bags rarely return to the same degree once fat is repositioned.
Can it be done with double eyelid surgery?
Yes, upper and lower eyelid procedures are often combined, which increases swelling but avoids two separate recoveries.
