Do you still look tired no matter how much you sleep? Does concealer help less 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 no amount of rest or skincare can fix.

The good news is that this is one of the most treatable concerns in aesthetic medicine — when 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 fillers around the eyes can realistically achieve, and what to look for when choosing a clinic in Bangkok. Everything you need to make a confident, informed decision — before you book anything.

What You’ll Learn in This Article Why eyes look tired — the anatomy behind tear trough hollowing and dark circles. What fillers around the eyes can (and cannot) treat, and how to identify which type of concern you have. The full risk and side effect profile of periorbital filler. How to choose a qualified, safe clinic for under-eye filler in Bangkok.

1. What Are Fillers Around the Eyes?

The under-eye area changes with age for three interconnected reasons — and understanding them is the first step toward choosing the right treatment.

Bone resorption

The orbital rim — the bony edge of the eye socket — gradually recedes with age. This reduces the skeletal foundation supporting the soft tissue above, allowing the lower eyelid to descend and the tear trough groove to deepen.

Fat pad descent and atrophy

The suborbicularis oculi fat (SOOF) — the fat pad directly beneath the lower eyelid — thins and descends over time, leaving a hollow in its wake. In some individuals, this process begins as early as the mid-20s, driven more by genetics than by age alone.

Skin thinning

Periorbital skin is the thinnest on the entire face. As collagen and elastin decline, the skin becomes increasingly transparent — allowing underlying structures (blood vessels, muscle, bone) to show through, contributing to a darkened, sunken appearance.

The result of all three: a structural hollow that casts a shadow — and a face that reads as fatigued, stressed, or unwell regardless of how much sleep you have had. This shadow cannot be resolved by skincare, cold compresses, or concealer — only by restoring the volume deficit beneath the skin.

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

Not all dark circles have the same cause — and choosing the wrong treatment won’t help, and may 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 reduces 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 colour.

Treating pigment-based dark circles with filler will not improve the discolouration and may create an overfilled, puffy appearance without addressing the underlying concern.

Better treatments for this type: Pico Laser (pigmentation treatment), Radiant & Bright Skin programme, or physician-prescribed topical brighteners.

2.3 Vascular darkness — filler partially helps

A purplish-blue tint caused by blood vessels showing through very thin skin. Filler adds tissue between the skin and vessels, which can reduce the translucency — but it is not the primary treatment. Pluryal polynucleotide injections and ซิลเฟิร์ม เอ็กซ์ can improve periorbital skin quality for this type.

At Bibi Clinic, VISIA® skin analysis is used before any treatment to objectively categorise your concern. Your physician will be direct with you about whether filler is the right treatment — or whether a different approach serves you better.

3. What Fillers Around the Eyes Can (and Cannot) Treat

Fillers around the eyes can treat:

• Tear trough hollowing — the primary target: restoring the missing volume in the groove between the lower eyelid and cheek
• Shadow-based dark circles — when the darkness is caused by the hollow rather than pigmentation
• Sunken or deflated lower eyelid appearance — loss of the subtle fullness that characterises youth in the periorbital area
• Tired appearance at rest — the face reading as fatigued regardless of actual rest
• Mild lower eyelid puffiness — in some anatomies, filler placed in the adjacent tear trough can visually balance mild puffy eye bags (though it does not reduce the bags themselves)

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 assessment
• Excess eyelid skin laxity — a surgical concern
• Fine surface wrinkles — better addressed with skin-quality treatments like Sylfirm X

4. Who Is a Good Candidate?

Fillers around the eyes work best for those whose primary concern is structural: hollowing, tear trough depth, and shadow-based darkness. At Bibi Clinic, the physician assesses all of these at consultation.

Good candidates

• Adults with visible hollowing or a groove beneath the eye (tear trough)
• Those whose darkness is primarily shadow-based (not pigmentation)
• Those 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 the late 20s, particularly in those with a genetic predisposition
• Those seeking ‘refreshed, not altered’ outcomes — the under-eye is the area where this philosophy matters most

Not suitable

• Pregnancy or breastfeeding — contraindicated for all injectable treatments
• Severe lower eyelid fat pad protrusion (true eye bags) — filler will not address structural fat and may worsen appearance
• Purely pigment-based dark circles — filler will not improve skin colour
• Active infections, eczema, or periorbital inflammation — treatment must be deferred
• Bleeding disorders or anticoagulant medications — significantly elevated bruising and vascular risk

5. How Long Do Under-Eye Fillers Last?

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

• Product type — softer, more hydrophilic products may last shorter than denser formulations; the physician selects based on what is safest for the periorbital area
• Individual metabolism — varies significantly between patients; cannot be predicted before treatment
• Volume placed — conservative treatment (as Bibi Clinic practices) may require maintenance sooner than larger volume sessions
• Lifestyle — UV exposure and smoking accelerate HA breakdown

Individual results vary. Longevity estimates 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 post-treatment: no rubbing or touching the eye area, no intense exercise, no alcohol, no saunas or steam rooms
• Sleep with your head slightly elevated to minimise 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 required — they increase bruising risk
• Apply SPF 50 daily — UV exposure degrades HA and accelerates resorption
• Avoid high-intensity cardio for one week — elevated heart rate and blood pressure increase bruising

7. Risks and Side Effects

Like any injectable treatment, fillers around the eyes carry risks — and the under-eye area demands more precision than almost anywhere else on the face. That said, serious complications are uncommon when the right physician, the right product, and the right technique are in place. Here is what you need to know before deciding.

Common side effects (expected and temporary)

• รอยฟกช้ำ — more common here than other filler areas; typically resolves in 5–10 days
• บวม — 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 swelling has resolved

Uncommon side effects

• Tyndall effect — a bluish discolouration caused by filler placed too superficially. Occurs when an inappropriate product or injection depth is used. Managed with hyaluronidase. Rare in experienced hands.
• Prolonged oedema — swelling lasting more than two weeks; uncommon, may require hyaluronidase
• Lumpiness or irregularity — can occur if filler migrates or is unevenly distributed; typically massaged out or dissolved

9. Frequently Asked Questions

I’m in my late 20s and my tear troughs are genetic — is filler appropriate at this age?

Yes. Genetic tear trough hollowing responds well to filler at any adult age. The prejuvenation approach — treating a structural concern 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 results can be excellent.

How do I know if my dark circles are from hollowing or from pigmentation?

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

Will my eyes look puffy or swollen after filler?

Mild swelling for 24–48 hours is expected. 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 results once swelling has resolved.

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

The Tyndall effect is a bluish discolouration caused by filler placed too superficially in the skin. It occurs when an inappropriate product or an incorrect injection depth is used. It is rare when treatment is performed by an experienced physician using periorbital-specific products — which is why product selection and technique matter as much as the quantity injected.

Can I combine under-eye filler with other treatments?

Yes. Common combinations at Bibi Clinic include: Pico Laser for concurrent pigmentation concerns, ซิลเฟิร์ม เอ็กซ์ for overall periorbital skin quality, พลูเรียล for skin renewal, and cheek filler to improve the tear trough indirectly by restoring mid-face volume. Your physician will advise on safe sequencing.

What if I had under-eye filler elsewhere and want it dissolved?

Bibi Clinic can assess and, where clinically appropriate, dissolve previous HA filler with hyaluronidase. This is increasingly requested by patients seeking to correct over-treatment, migration, or Tyndall effect from prior procedures.

Is there downtime after tear trough filler?

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