In short
Not all dark circles are the same. They can come from hollowing that casts a shadow, from pigment, from visible vessels or from bags and loose skin, and they often overlap. Hyaluronic acid filler mainly helps hollowing: in a meta-analysis, 91% of patients were satisfied. For pigment or bags, it is not the answer.
Key points
- Before treating, the type must be clear: hollowing, pigment, vascular, bags or mixed.
- In a meta-analysis of 2,556 patients, satisfaction with tear trough filler was 91%.
- According to a systematic review, the effect lasts 8 to 12 months.
- Swelling and bruising are the most common effects, in about 1 in 5; a bluish tinge, in under 1%.
- The skin is very thin and the area has important vessels: it needs an experienced doctor.
Dark circles are one of the most common reasons people come to an aesthetic clinic, and one of the most often mistreated. The reason is simple: "dark circles" describes several different problems. Tear trough filler can transform one kind and make another look worse. Before deciding on anything, it is worth knowing which kind you have.
Why dark circles appear: the types
Reviews group them by cause [1][2]:
- Hollowing. With age, the area between the lower eyelid and the cheek loses volume and support. A groove forms, known as the tear trough, and it casts a shadow. You look tired even after a good night's sleep.
- Vascular. The eyelid skin is very thin and shows the blood vessels beneath, with a bluish or purple tone. It gets worse with tiredness, fluid retention or allergies.
- Pigmented. There is more pigment in the skin, with a brown tone. It can run in families and be more common in some skin types, or follow inflammation such as eczema or a habit of rubbing the eyes.
- Bags and loose skin. The fat around the eye pushes forward to form a bag, or the skin becomes lax. The shadow sits below the bag rather than in a hollow.
Most people have a mix of two or more types. That is why there is no single treatment for "dark circles".
How the type is identified
At the consultation, the doctor examines the area with light from the front and from above, at rest and while you look upwards. Some clues:
- If the shadow changes a lot with the light, hollowing dominates.
- If the colour fades when the skin is gently stretched, there is usually a vascular or thin-skin component.
- If the brown colour stays when the skin is stretched, there is pigment.
- If a bulge appears when you look up, there are bags.
The doctor will also ask about allergies, sleep, medication, previous treatments in the area and whether puffiness is worse in the morning, which matters before any filler is used.
Which treatment suits which type
A systematic review of 39 studies summarises it as follows [2]:
- Hollowing: fillers and fat grafting work best when the cause is volume loss.
- Pigment: depigmenting creams prescribed by a doctor, chemical peels and some lasers, with daily sun protection.
- Vascular component: lasers and intense pulsed light give a mild to moderate improvement.
- Bags or loose skin: eyelid surgery is the appropriate option. Filler does not correct them and can make them more noticeable.
Some treatments are widely marketed for dark circles, such as carboxytherapy or platelet-rich plasma. They appear in the literature, but only in small studies, and the authors warn that good-quality evidence is scarce [2].
When tear trough filler helps
Filler is for dark circles caused by hollowing. Small amounts of a hyaluronic acid suitable for the area are placed deep, close to the bone at the rim of the eye socket. It can be done with a needle or a cannula [3].
Results are good when the indication is right. In a meta-analysis of 31 studies with 2,556 patients, 91% were satisfied with tear trough filler [4]. A systematic review put the duration of effect at 8 to 12 months [3].
It does not help if the main problem is pigment, prominent fat bags, very lax skin or puffiness that comes and goes. In those cases, filler can make things look worse.
What to expect, realistically
- Less shadow and a smoother transition between eyelid and cheek.
- A more rested look, with no visible filler if the amount is modest.
- Pigment does not change with filler, even if the shadow lessens.
- A review at two to three weeks to decide whether a small adjustment is needed.
Risks, and who it is not for
The skin under the eye is very thin and the area has important blood vessels. That makes it one of the areas that demands the most experience.
In the meta-analysis above, the most common effects were swelling (19.2%) and bruising (18.4%), followed by redness (7.1%) and small irregularities or lumps (5.3%). A bluish tinge from filler placed too superficially occurred in 0.9% [4].
There are delayed complications too. In a review of cases, the most common was persistent swelling, followed by nodules, appearing on average around 17 months after treatment [5]. Swelling over the cheekbone is another known complication of this area; infection and biofilm, a layer of bacteria on the product, are uncommon [6].
The most serious complication is vascular, which can damage the skin and, exceptionally, the eyesight [6]. In a review of 198 cases of filler-related vision loss, most followed injections in the nose, forehead and between the brows, and very few in the eye area [8]. Even so, anyone treating this area should know its anatomy and keep on site the enzyme that dissolves hyaluronic acid [7].
Tear trough filler is not recommended in pregnancy or while breastfeeding, with an active infection or allergy in the area, with prominent bags, with very lax skin, or if your eyelids are often puffy in the morning.
How we approach it at Rejuvelook
At our clinic in Fuengirola, we start by working out which type of dark circle you have. If filler is right for you, we use small amounts, placed deep, and review the result once it has settled. If yours is not a filler case, we will tell you and point you towards what could help, even if it is not something we offer. Treating dark circles well starts with not treating the ones that do not need it. We see patients in English or Spanish.

With caveats
When to see a doctor
Book a medical consultation, or go to A&E if it is severe or sudden, if you notice:
- Severe pain, paleness or purple, blotchy skin after tear trough filler: contact the clinic that treated you straight away.
- Any change in your vision or pain in the eye after an injection: go to A&E (urgencias) or call 112.
- A dark circle that appears suddenly on one side only, with pain or changes in vision: see a doctor.
- Persistent swelling, lumps or a bluish tinge weeks or months after filler.
- Itchy, flaky or eczema-prone skin around the eyes: usually a skin or allergy problem to treat first.
Frequently asked
Does tear trough filler hurt?
A numbing cream is applied and the product usually contains a local anaesthetic. Most people describe it as manageable discomfort. The session is short.
Can I go to work the next day?
Usually yes. A small bruise or slight swelling may appear in the first few days, and you can cover it with make-up from the next day. Avoid strenuous exercise and saunas for the first 24 hours.
When will I see the final result?
You see an improvement straight away, but the final result is judged at two to three weeks, once the swelling has gone down. That is when the review takes place.
Can I go in the sun or fly afterwards?
Flying is fine. For the first few days avoid strong sun and intense heat. If your dark circles have a pigment component, daily sun protection is part of the treatment, especially under the Andalusian sun.
What if I do not like the result?
Hyaluronic acid can be dissolved with an enzyme at the clinic. That is one of the reasons it is the material of choice for this area, rather than products that cannot be removed.
Can it be combined with other treatments?
Yes. Dark circles often improve more if cheek support is restored as well, or if pigment is treated alongside. The doctor decides the order.
I had tear trough filler a while ago. Can I have more?
Yes, but first the doctor needs to check whether product is still there, especially if you notice puffiness or a bluish tinge. Adding filler on top of filler that has not been absorbed is a common cause of poor results.
