Under-eye light filler supports the hollow beneath the eye — the tear trough — to soften the shadow it creates and give the eyes a more rested appearance.
It is called light filler for a reason: once the hollow is supported, light reflects without casting a shadow and the area looks brighter. Part of what reads as darkness is in fact shadow.
This is the thinnest-skinned and most selective area of the face. Here, choosing the right patient matters more than the technique itself. I set out the wider picture, and the other areas, on the dermal fillers page.
Why the under-eye hollows and darkens
- Volume loss. With age the bone beneath the eye recedes and the fat pads diminish, creating a step between the eye and the cheek.
- Shadowing. Light does not reach into that step, so the area looks dark.
- Vascular visibility. Under-eye skin is the thinnest on the face, and the vessels beneath it add to the darkness.
These three causes carry different weight in different people, and the treatment option changes accordingly. If your darkness is pigment-related, filler will not produce the result you expect; we distinguish this at consultation.
This treatment does not suit everyone
This is the section I most want to underline on this page.
A suitable candidate has a defined hollow — a tear trough — beneath the eye.
An unsuitable candidate has visible under-eye bags. Placing filler beneath an eye with bags makes them more prominent. In that case the appropriate approach is different and I will guide you to it.
Around the eyes the decision depends on the cause: if hollowing dominates, mesotherapy is not enough and filler is discussed; if thin skin, dark circles and mild puffiness dominate, HA–amino acid biorevitalisers or polynucleotide products come forward. The product is chosen at the consultation. I cover those two options separately on the Jalupro Young Eye and Rejuran I pages.
Sometimes the hollowing under the eye is caused not by the under-eye itself but by loss of support in the cheek. In that situation the mid-face is supported first, and the appearance often improves without touching the under-eye at all.
How the treatment works
- Assessment. The depth of the hollow, the presence of bags and the state of cheek support are evaluated together.
- Product selection. Products developed for this area — fine in structure and low in water binding — are used.
- Application. A blunt-tip cannula, deep plane, small quantities. The treatment takes about 20 minutes.
Average longevity is 9 to 12 months. I prefer to do less and complete later if needed; the under-eye is where excess is noticed fastest.
Safety and anatomy
The periorbital area is vascularly dense and technique carries significant weight in this treatment.
The main consideration in filler treatment is placing the product in the correct plane relative to the tissue and the vascular anatomy. For that reason I prefer a blunt-tip cannula in suitable areas, working in the deep plane and advancing slowly. In a large published cohort study, the rate of vascular events in experienced hands was reported as roughly one in 6,400 syringes with a needle and one in 40,000 with a cannula — infrequent with either technique, and less frequent still with a cannula 1. Experience also matters: in the same study, rates were markedly lower among physicians with more than five years of practice. The fact that hyaluronic acid based products can be dissolved if needed provides an additional margin of safety; I explain this on the filler dissolving page.
Aftercare
A few simple points on the first day are enough to keep the result where we planned it:
- Do not apply make-up or cosmetic products to the treated area for the first 24 hours.
- Do not massage or rub the treated area.
- Avoid very hot showers for the first 24 hours, and saunas and steam rooms for the first week.
- Avoid heavy exercise and intense cardio for the first week.
- Avoid alcohol on the day of treatment, and do not smoke for the first 4 hours.
- Drink plenty of water; hyaluronic acid binds water in the tissue, which helps the result settle.
- Sleep with your head elevated on the first night.
- Avoid heavy-framed glasses for the first two days.
- Reduce salt intake for the first few days; this helps limit swelling.
Short-lived mild redness, tenderness or a small bruise may appear at the injection points; these resolve on their own within a few days. Because an allergic reaction can occur rarely, treatments are carried out under medical supervision.
What we review together at your consultation
- Pregnancy and breastfeeding
- Active skin infection or an unhealed wound in the treatment area
- Known hypersensitivity to filler components
- The active phase of an autoimmune condition, if you have one
- Permanent filler previously placed in the same area
- Your current medication and general health
- Tendency to periorbital swelling or slow lymphatic drainage
- Visible under-eye bags
If one of these applies to you, we plan a more suitable alternative rather than the treatment.
Planning your visit
The clinic is in Nişantaşı, Şişli, Istanbul, about 45 minutes from Istanbul Airport. A stay of 2–3 days covers arrival, consultation and treatment, and departure. Injectable fillers need no recovery period; mild swelling may last two to three days, so if you have an event we plan the appointment around it. I do not commit to a plan over messages: we speak before you travel so you know what is realistic, and we confirm it in person on the day. Flying is usually fine 24 hours after an injectable treatment. Remote follow-up and contact are provided, and consultations are held in English.
Pricing
Under the applicable regulations, price information cannot be published on our website. The cost of a treatment depends on the product used, the technique chosen and the extent of the treatment. You can call the clinic for detailed information.
Frequently asked questions
I have under-eye bags. Am I a candidate?
If bags are prominent this treatment is not suitable; filler makes them more visible. At consultation we distinguish hollowing from bagging. The two can coexist, and in that case the order of treatment becomes important.
Will my under-eye look blue (Tyndall effect)?
Product placed too close to the skin can reflect light with a bluish cast, known as the Tyndall effect. Placing product deep, on bone, markedly reduces that possibility.
Can I get lumpiness (a sausage-like appearance) under the eye?
That appearance usually follows from a product too dense for the area, or from superficial placement. Working deep with a fine, area-specific product, it is not an expected outcome. If an irregularity does remain, hyaluronic acid products can be dissolved 3.
