Under-Eye Filler in Busan: Who Is a Suitable Candidate?

Why under-eye hollows happen

The area under the eyes is one of the first places people notice looking tired. A shadowed groove between the lower eyelid and the cheek, often called a tear trough, can make you look fatigued even after a full night's sleep. These hollows can come from genetics, natural bone structure, loss of fat and volume with age, or thinning skin that lets underlying blood vessels show through.

Under-eye filler places a small amount of a soft hyaluronic acid gel into the hollow to soften the shadow. It is a popular treatment in Korea, but it is also one of the more technically demanding filler areas, and not everyone is a suitable candidate. This guide explains who tends to be considered and who may be better served by another approach.

Who may be a suitable candidate

A doctor will assess your eyes in person, but people who are often considered suitable tend to share some features:

A true hollow. The darkness under the eye is mainly a shadow caused by a groove or volume loss, not pigment or puffiness.
Reasonably good skin quality. Skin that is not very thin or loose can usually hide a small amount of filler more smoothly.
Little or no under-eye bags. Filler is meant to fill a groove, not to hide a bulge.
Realistic expectations. The aim is a softer, more rested look, not a completely flat or "airbrushed" area.
Good general health. No active infection near the eyes, and no conditions that make injections unsafe.

Who may not be a good candidate

In several situations, under-eye filler may not help, or may make things look worse. A doctor may suggest a different plan if you have:

Puffy under-eye bags. Bags are often caused by fat pushing forward. Adding filler around them can increase puffiness. A surgical opinion is sometimes more appropriate.
Fluid retention or frequent swelling. Hyaluronic acid attracts water, and people prone to morning puffiness may notice more swelling after filler.
Dark circles from pigment. Brown or grey discolouration is a skin colour issue rather than a volume issue. Pigment-focused treatments may be discussed instead; see our pigmentation overview.
Very thin or crepey skin. Filler may show through as a bluish tint or visible lumps. Skin quality treatments are sometimes considered first.
Allergies or sensitivities. Tell your doctor about any previous reactions to fillers or numbing creams.
Pregnancy or breastfeeding. Elective injectables are usually postponed; consult a doctor.

Understanding the risks

The under-eye area has delicate skin and many small blood vessels, so careful technique is essential.

Common effects. Swelling, bruising and tenderness are common and usually settle over days.
Visible filler or a blue tint. If filler sits too close to the surface, it can sometimes show as a bluish colour, known as the Tyndall effect. Hyaluronic acid filler can usually be dissolved if this happens.
Lumps or prolonged swelling. Some people develop lumps or swelling that lasts longer. A doctor can assess and advise.
Vascular complications. Rarely, filler can affect a blood vessel near the eye, which may threaten the skin or, in very rare cases, vision. Severe pain, skin colour changes or any change in vision after treatment needs immediate medical attention.

Because of these risks, under-eye filler should be performed by a physician who is experienced with the area and prepared to manage complications.

Under-eye filler at Daybeau Clinic Seomyeon

At Daybeau Clinic Seomyeon, under-eye filler is quoted after an in-person consultation, because the amount of product varies and suitability must be checked first. You will know the cost before treatment, and payment is made on the day after the consultation confirms your plan. Our dermal filler page explains our general approach.

If filler is not right for you, the doctor may talk about alternatives that focus on skin quality, such as skin boosters, which are listed with first-visit prices in KRW (VAT excluded, 10% VAT added at payment, checked October 2026). For example, Rejuran 2cc is 139,000 KRW on our price list. Whether any treatment suits your under-eye area is decided at consultation.

Preparing for your appointment

Come without eye makeup if possible. This makes the assessment easier.
Bring a list of medications and supplements. Some can increase bruising.
Mention previous treatments. Include any earlier fillers or eye surgery.
Allow time before flying or events. Swelling and bruising may need a few days to settle.
