Under-Eye Filler Lumps —
Which Problem Is It?

Atelier Aesthetics · Medical Director: Dr. Sin Yong · Updated 23 Oct 2026

A lump, a bluish tint or new puffiness after tear trough filler can come from five different problems, and the correction depends on which one it is. This page sorts them by timing and look, explains how Dr Sin Yong assesses them at Atelier, and lists the signs that cannot wait.

The Mechanism

Why The Lower Lid Shows Everything

Book a Consultation

Skin on the lower lid is very thin, with little fat under it, and fluid drains from the area slowly. Two ligaments, the tear trough and orbicularis retaining ligaments, shape the area and help explain why problems show here.

The infraorbital hollow is described as the area most prone to adverse events after filler. Most are mild and pass, and they tend to follow the volume used and the technique. One series (Wilde 2023) followed 583 patients through 1,452 tear trough treatments, averaging 0.34 mL per side: 10% reported swelling, an irregular contour in 4.6% and a bluish tint in 3.3%. Filler was dissolved in 1.9% of eyes.

Reason One
Thin Skin
Little tissue covers the product. A bead placed too close to the surface can be seen or felt, and shallow gel can show through as a tint.
Reason Two
Above The Septum
Product placed above the malar septum can hold fluid there, which shows as puffiness rather than a lump.
Reason Three
Slow Drainage
Puffiness from trapped fluid is often worse in the morning or after a salty meal.
Reason Four
Filler That Stays
Hyaluronic acid in the midface can still be present years after injection, and swelling from retained filler has been reported up to nine years later.

Types

Five Problems That Feel Alike

Timing and appearance narrow it down first. In the first days to two weeks, a firm area with bruising and swelling is usually ordinary settling: gentle care and a check, without pressing on it unless advised to.

A visible or palpable bead or ridge that stays after that usually means superficial placement or a large bolus. If it is hyaluronic acid, targeted hyaluronidase is usually the answer, and that problem is covered here. The other four each have their own page: delayed nodules, swelling and puffiness, the Tyndall effect and non-HA fillers.

Tear trough and lower eyelid
Assessment
History of product, amount, dates and top-ups, then examination at rest and in expression
Modalities
Targeted, staged hyaluronidase where the lump is hyaluronic acid; other routes, set by the material, where the enzyme cannot act
Review
Once swelling has settled, and two to four weeks after any dissolving
Type I
A Late Nodule
A new firm or tender nodule months or years after filler. The term describes a symptom rather than a diagnosis, so the cause is found before anything is injected.
Type II
Puffiness
Soft bags that appear weeks to years later and look worse on waking or after a salty meal. It may be fluid, retained filler or both, and the two are separated first.
Type III
A Blue-Grey Cast
A persisting tint is usually the Tyndall effect from hyaluronic acid placed too superficially. It is not a bruise and will not fade on its own.
Type IV
Material That Will Not Dissolve
A hard lump weeks to months after a PLLA, CaHA, PCL or PDLLA-based product is often the material clustering. Hyaluronidase does not dissolve it.

The Decision

History Before Hyaluronidase

At Atelier, Dr SY starts with your history: which product, how much, when, who injected it and whether there were top-ups. The area is then felt and examined at rest and in expression.

A hyaluronic acid lump. Hyaluronidase is targeted at the deposit after a small skin test dose, and the work is staged: a conservative amount, a check, then more only if needed. Nothing new is injected on the same day, and the area is left to settle, then reassessed at two to four weeks. The full sequence is on filler correction. Puffiness from filler that has spread is one of the filler migration signs, and problems elsewhere on the face are covered on dermal filler complications.

What not to do. Each of these tends to make things harder to put right:

  • Topping up around a lump or a puffy patch to even it out. More filler cannot correct a face that already holds too much.
  • Firm or repeated massage, unless the injecting doctor asked for it for a specific reason.
  • Steroid injected into a lump before anyone has worked out what the lump is.
  • Dissolving devices or products bought online for use at home.

Afterwards. Many people decide against filler under the eye again. Some eyes were never a filler problem: true fat bags (see eye bag causes), thin crepey skin and pigment (see dark eye circle types) need other approaches. Where a hollow remains and refilling suits, a smaller amount placed in a deeper plane is the aim, as on tear trough refinement.

Safety

Warning signs: when to get help now

Most under-eye lumps can wait for a planned assessment. These signs cannot.

  1. Vision change or eye pain after filler: call 995 or go to an emergency department immediately, and contact the injecting doctor. Go directly: do not travel to the clinic first, and do not drive yourself.
  2. Pale, dusky or mottled skin, or pain that keeps getting worse: this needs urgent assessment now. Do not wait. Contact the clinic that injected you straight away; if you cannot reach it, go to A&E. These can be signs of filler inside a blood vessel; see vascular occlusion warning signs.
  3. A hot, red and tender lump, with or without fever: this needs prompt review by a doctor. It is examined, not massaged.
  4. A lump, tint or puffiness without these signs: book an assessment and bring any record of what was injected.

FAQ

Under-Eye Filler Lumps — Common Questions

Ask a Question
Timing and feel help, and bags that were there before treatment are often mistaken for filler. If the bump arrived after the injection, has an edge you can feel when you press gently, or carries a bluish tint, filler is the likelier cause. A bulge that gets bigger when you look up is orbital fat. Dr SY checks this at rest and in expression.
Pain is not the test. Firmness, bruising and swelling in the first fortnight are usually settling, and gentle care is enough. A lump that is still there after that should be looked at rather than rubbed: under the eye, hyaluronic acid can last for years, and a blue-grey tint will not fade on its own. A lump that turns hot, red or tender needs prompt attention.
Hyaluronidase is aimed at the excess deposit rather than everything that was injected. The enzyme also acts on your own hyaluronic acid in that spot, so the area can look flatter for a time; this is replaced within about two weeks. If a hollow remains once the area has settled, it is reassessed then, never refilled on the day of dissolving.
Yes. Hyaluronic acid in many cases outlasts the time quoted for it, and under the eye it can still be present, and still cause swelling, many years later. Being told a product lasts a year or so does not rule it out, which is why Dr SY asks about every treatment you have had, however long ago.
Hyaluronidase is widely used, but it is a medicine in its own right. Swelling and bruising can follow, and an allergic reaction is rare. Published guidance recommends a small test dose first, and at Atelier the enzyme is aimed at the deposit in conservative, staged amounts rather than all at once. Dr SY goes through these risks with you before anything is injected.
Possibly, but not straight away. At Atelier nothing new is injected for at least two to four weeks after dissolving, and the area is reassessed once the swelling has gone. Where a hollow remains and refilling suits, the usual principle is a smaller amount, placed deeper.
