Tear trough filler typically lasts between six and twelve months. The range is wide because longevity depends on three things: which product is used, how it’s placed, and the individual patient’s metabolism. At Centre for Surgery, our standard choice for this area is Teosyal Puresense Redensity 2 — a specific hyaluronic acid formulation designed for the thin skin and delicate anatomy beneath the eye. With proper placement, results in this area can last six to nine months on a first treatment, and up to a year once the appropriate volume for the patient has been established.
RELATED: Under Eye Fillers – Are Tear Trough Injections Worth It?
There are occasional reports of tear trough filler lasting two to three years in individual patients. This isn’t necessarily a positive — it can indicate filler that has migrated or accumulated in the wrong tissue plane rather than integrating and dispersing normally. Patients who notice an asymmetric or uneven look long after treatment often need their old filler dissolved before any new treatment can be planned cleanly.
What affects how long the filler lasts
The product chosen. Tear trough filler is not a place to use a generic or robust filler designed for the cheek or lip. The area requires a low-G’ (softer) hyaluronic acid with minimal water-binding, otherwise the patient ends up with the characteristic puffy or blue-tinged appearance under the eye known as the Tyndall effect.
Depth of injection. Filler placed correctly onto the periosteum — the layer covering the bone of the orbital rim — integrates and lasts longer. Filler placed too superficially can move, lump, or appear bluish.
Patient metabolism. Younger, leaner, more athletically active patients metabolise filler faster. Slower metabolism in older patients means filler tends to last longer.
Smoking and sun exposure. Both accelerate filler breakdown through chronic inflammation.
Volume placed. Conservative first treatments are deliberately under-corrected so the patient can return for a top-up at two to four weeks once initial swelling has settled. The combined result usually lasts longer than a single larger dose because it sits more evenly.
Can tear trough filler eliminate eye bags?
Under-eye bags are pockets of orbital fat that herniate forward as the septum (the membrane holding fat in place behind the eye) weakens with age. Filler does not remove this fat.
What it can do is soften the visual transition between the bag and the cheek. By filling the hollow that sits below the bag — the tear trough proper — the eye area reads as a smoother continuous surface, and the bag itself becomes less prominent. This is camouflage, not correction.
RELATED: What Is Tear Trough Deformity?
For patients with significant fat herniation, filler is the wrong tool. The cleaner solution is lower blepharoplasty, where the excess fat is repositioned or removed surgically. Trying to camouflage large bags with filler often makes the under-eye area look heavier rather than lighter.

Does the treatment hurt?
Patients usually describe the sensation as pressure rather than pain. We use topical anaesthetic cream applied for fifteen to twenty minutes before the procedure, and the filler product itself contains lidocaine. Where appropriate, a blunt cannula is used instead of a needle — this technique reduces both discomfort and the risk of vascular injury.
A typical session takes about thirty minutes including the numbing wait. Most patients return to normal activities immediately, with the caveat that mild bruising is possible in this area because the skin is thin and the underlying tissue is vascular.
The risks worth understanding
The tear trough is one of the highest-risk areas of the face for filler. Two risks merit a separate conversation:
Vascular occlusion. The under-eye area has blood vessels that connect to the ophthalmic artery. Filler accidentally entering one of these vessels can travel back toward the eye and cause skin necrosis or, in extreme cases, vision loss. The risk is very low when treatment is performed by an experienced injector using cannula technique and low-pressure injection, but it cannot be reduced to zero. This is the main reason this area should never be treated by a non-medical injector.
Migration and chronic puffiness. Even when nothing acute goes wrong, filler placed too superficially or in the wrong layer can sit visibly under the skin for years. Patients sometimes present months or years after another clinic’s treatment with persistent under-eye puffiness that they assumed was their own swelling — but is actually old filler that needs dissolving with hyalase.
RELATED: Why Under Eye Filler is Not For Everyone
Who is not a good candidate
– Patients with significant under-eye bags requiring surgical correction
– Patients with very thin or pigmented under-eye skin where filler will show through
– Patients with active eczema or skin infection in the area
– Patients with a history of recurrent eye infections or chronic dry eye
– Pregnancy and breastfeeding
– Patients with previous tear trough filler that hasn’t been assessed and, if needed, dissolved first
Common questions
Is one session enough?
Usually two. A conservative first session establishes how the patient’s tissue holds the filler, and a top-up at two to four weeks refines the result. After that, maintenance is typically annual.
What does dissolving the filler involve if I want to reverse it?
A small amount of hyaluronidase enzyme is injected into the treated area. The filler breaks down within twenty-four to forty-eight hours. The treatment is quick and the area can be re-treated about two weeks later if needed.
Will it look obvious that I’ve had it done?
A well-placed conservative treatment should not. People often comment that the patient looks rested or less tired without identifying what’s changed. Over-correction is the most common reason patients look “done” — which is why the conservative two-stage protocol matters.
