Do you still look tired no matter how much you sleep? Does concealer work less well than it used to—or not at all?

For many people, the cause is structural: a hollow beneath the lower eyelid that casts a shadow that no amount of rest or skincare can fix.

The good news is that this is one of the most treatable concerns in aesthetic medicine—provided the right approach is chosen.

This article explains why the under-eye area looks the way it does, how to identify which type of concern you have, what results you can realistically expect from fillers around the eyes, and what to look for when choosing a clinic in Bangkok. Everything you need to make a confident, informed decision—before you book anything.

The result of all three: a a structural cavity that casts a shadow — and a face that looks tired, stressed, or unwell no matter how much sleep you’ve had. This shadow cannot be corrected with skincare, cold compresses, or concealer—only by restoring the lost volume beneath the skin.

2. Dark Circles & Hollow Under Eyes: Which Type Do You Have?

Not all dark circles are caused by the same thing—and choosing the wrong treatment won’t help and may even make things worse.

Before considering any injectable treatment, identifying your specific type is the most important step.

2.1 Shadow-based (structural) darkness — filler works

This is the primary indication for tear trough filler. The darkness is caused entirely by the hollow casting a shadow.

There is no pigment in the skin itself—just a depression that intercepts light. When the hollow is filled, the shadow disappears.

How to identify it: Hold a light source directly below your eyes and tilt your face downward. If the darkness lessens or disappears in this light, it is structural—filler will help.

2.2 Pigment-based darkness — filler does not work

Caused by melanin deposits in the skin itself. Filler adds volume but has no effect on skin color.

Treating pigment-based dark circles with fillers will not improve the discoloration and may result in an overfilled, puffy appearance without addressing the underlying issue.

Better treatments for this type: Pico Laser (Pigmentation Treatment), Radiant & Bright Skin Program, or physician-prescribed topical skin-brightening products.

2.3 Vascular darkness — filler helps to some extent

A purplish-blue tint caused by blood vessels showing through very thin skin. Filler adds tissue between the skin and the blood vessels, which can reduce the translucency—but it is not the primary treatment. Pluryal Polynucleotide Injections and Sylfirm X can improve the quality of the periorbital skin in this type of case.

At Bibi Clinic, VISIA® Skin Analysis is used before any treatment to objectively assess your concern. Your doctor will be straightforward with you about whether filler is the right treatment—or whether a different approach would be better for you.

3. What Eye Area Fillers Can (and Cannot) Treat

Fillers Around the Eyes can treat:

• Tear Trough Hollowing — the primary goal: restoring the lost volume in the groove between the lower eyelid and the cheek
• Shadow-based dark circles — when the darkness is caused by the hollow rather than pigmentation
• Sunken or deflated appearance of the lower eyelid — loss of the subtle fullness that characterizes youth in the periorbital area
• A tired appearance at rest — the face appearing tired regardless of how much rest one has actually had
• Mild puffiness of the lower eyelids — In some cases, filler injected into the adjacent tear trough can visually balance out mild puffiness under the eyes (though it does not reduce the puffiness itself)

Fillers Around the Eyes cannot address:

• Pigment-based dark circles — these require laser or topical treatment
• Significant fat pad protrusion (true eye bags) — these require surgical evaluation
• Excess Eyelid Skin Laxity — A Surgical Concern
• Fine surface wrinkles — best treated with skin-rejuvenating treatments like Sylfirm X

4. Who Is a Good Candidate?

Fillers around the eyes are most effective for people whose primary concern is structural in nature: hollowing, the depth of the tear troughs, and shadow-induced dark circles. At Bibi Clinic, the doctor evaluates all of these factors during the consultation.

Good candidates

• Adults with visible hollowing or a groove beneath the eye (tear trough)
• Those whose darkness is primarily due to shadows (not pigmentation)
• People Who Look More Tired Than They Feel — An Anatomy-Driven Discrepancy Between Appearance and Reality
• Adults of any age—tear trough hollowing can be significant even in one’s late 20s, particularly in those with a genetic predisposition
• Those seeking ‘refreshed, not altered’ outcomes — the under-eye area is where this philosophy matters most

Not suitable

• Pregnancy or Breastfeeding — Contraindicated for all injectable treatments
• Severe protrusion of the lower eyelid fat pad (true eye bags) — Fillers will not address structural fat and may make the appearance worse
• Dark circles caused solely by pigmentation — Filler will not improve skin tone
• Active infections, eczema, or periorbital inflammation — Treatment must be postponed
• Bleeding disorders or anticoagulant medications — significantly increased risk of bruising and vascular complications

5. How Long Do Under-Eye Fillers Last?

Typical lifespan: 9–18 months — longer than lip fillers because the tear trough area involves less movement. Key factors:

• Product Type — Softer, more hydrophilic products may have a shorter lifespan than denser formulations; the physician makes the selection based on what is safest for the periorbital area.
• Individual metabolism — varies significantly from patient to patient; cannot be predicted before treatment
• Volume placed — Conservative treatment (as practiced at Bibi Clinic) may require follow-up sooner than sessions involving larger volumes.
• Lifestyle — UV exposure and smoking accelerate the breakdown of hyaluronic acid

Results may vary from person to person. Estimates of how long the results will last are based on clinical averages and do not guarantee a specific duration for any individual patient.

6. Aftercare: What to Avoid

• For 24–48 hours after treatment: Do not rub or touch the eye area; avoid intense exercise, alcohol, saunas, and steam rooms.
• Sleep with your head slightly elevated to minimize swelling—avoid sleeping face-down
• Do not apply makeup to the under-eye area for at least 24 hours
• Avoid anti-inflammatory medications (aspirin, ibuprofen) unless medically necessary—they increase the risk of bruising
• Apply SPF 50 daily — UV exposure breaks down hyaluronic acid and accelerates its resorption
• Avoid high-intensity cardio for one week—an elevated heart rate and blood pressure can increase bruising

7. Risks and Side Effects

Like any injectable treatment, fillers around the eyes carry risks—and the under-eye area requires more precision than almost any other part of the face. That said, serious complications are rare when the right doctor, the right product, and the right technique are used. Here’s what you need to know before making a decision.

Common side effects (expected and temporary)

• Bruising — more common here than in other areas where fillers are used; typically resolves in 5–10 days
• Swelling — HA attracts water; peaks at 24–48 hours and resolves within one to two weeks
• Temporary Asymmetry — One side may swell more than the other; reassess at the 2-week follow-up once the swelling has subsided.

Uncommon side effects

• Tyndall effect — A bluish discoloration caused by filler injected too superficially. Occurs when an inappropriate product or injection depth is used. Treated with hyaluronidase. Rare when performed by an experienced practitioner.
• Prolonged edema — swelling lasting more than two weeks; uncommon, may require hyaluronidase
• Lumpiness or irregularity — may occur if the filler migrates or is unevenly distributed; it is typically massaged out or dissolved

9. Frequently Asked Questions

I’m in my late 20s and my under-eye hollows are genetic—is filler appropriate at this age?

Yes. Genetic tear trough hollowing responds well to fillers at any age in adults. The prejuvenation approach — Treating a structural issue conservatively before it becomes more pronounced — is clinically sound. Very small volumes (0.3–0.5 cc per side) are typically appropriate for younger patients, and the results can be excellent.

How can I tell if my dark circles are caused by hollowing or pigmentation?

A useful self-test: Hold a light source directly below your face and tilt your head back. If the darkness lessens or disappears in this position, it is caused by shadows—filler will help. If it persists regardless of the angle of the light, it is likely pigment-based—see our Pigmentation Treatment Page instead. Your Bibi Clinic physician will confirm this during your consultation using VISIA® imaging.

Will my eyes look puffy or swollen after getting fillers?

Mild swelling is expected for 24–48 hours. Significant puffiness is almost always the result of over-treatment — too much product, or a product that attracts too much water. Bibi Clinic’s conservative approach actively prevents this. The 2-week follow-up is specifically designed to review the results once the swelling has subsided.

What is the Tyndall effect, and how can I prevent it?

The Tyndall effect is a bluish discoloration caused by filler injected too close to the skin's surface. It occurs when an inappropriate product or an incorrect injection depth is used. It is rare for treatment to be performed by an experienced physician using products specifically designed for the periorbital area—which is why product selection and technique are just as important as the amount injected.

Can I combine under-eye filler with other treatments?

Yes. Common combinations at Bibi Clinic include: Pico Laser For concurrent pigmentation concerns, Sylfirm X for overall periorbital skin quality, Pluryal for skin renewal, and cheek filler to indirectly improve the tear trough by restoring mid-face volume. Your physician will advise you on the safest sequence of treatments.

What if I had under-eye filler done somewhere else and want it dissolved?

Bibi Clinic can evaluate and, when clinically appropriate, dissolve previous HA fillers using hyaluronidase. This procedure is increasingly requested by patients seeking to correct over-treatment, migration, or the Tyndall effect resulting from previous procedures.

Is there any downtime after tear trough filler?

No mandatory downtime. Most patients resume their normal activities the same day. Plan for 5–10 days if you have an important event—bruising is more common around the eyes than in other areas treated with fillers, and some patients prefer to plan accordingly.
