Under-eye filler lumps and nodules:
what they are and how they are corrected

Why does under-eye filler cause lumps?

Because the lower eyelid is the least forgiving place in the face to put filler. The skin is among the thinnest on the body, there is very little fat between it and the muscle, and the area drains fluid poorly. A volume of filler that would be invisible in the cheek can show as a ridge or bead under the eye, and a gel that draws in water can turn a hollow into a bag. The infraorbital hollow has been described as the area of the face most prone to filler adverse events (Funt, J Clin Aesthet Dermatol 2011).

Anatomy explains much of it. A true ligament, the tear trough ligament, tethers the skin to bone along the inner lower eyelid and continues outward as the orbicularis retaining ligament (Wong, Plast Reconstr Surg 2012). Along the tear trough the muscle attaches directly to bone; along the lid–cheek junction it attaches through that ligament, which is why cadaver work suggests different depths for the two areas (Haddock, Plast Reconstr Surg 2009). Filler placed above those planes, or too much of it, is what tends to show.

What is the lump most likely to be?

Timing, feel and colour narrow it down before any treatment is discussed. The table below is a starting point for a conversation with a doctor, not a diagnosis.

How common are these? In a series of 583 patients who had 1,452 tear trough treatments with a mean of 0.34 mL per side, swelling occurred in 10%, contour irregularity in 4.6% and a bluish tint in 3.3%, and filler was dissolved in 1.9% of eyes; larger volumes significantly increased the risk of swelling (Wilde, PRS Global Open 2023). Most adverse events after hyaluronic acid filler are mild, transient and related to volume and technique (Signorini, Plast Reconstr Surg 2016; Funt and Pavicic, Clin Cosmet Investig Dermatol 2013).

How Dr Sin Yong assesses an under-eye lump

He starts with the history: which product, how much, when, by whom, and whether there have been top-ups. Records from the previous clinic help, but many patients do not know what was injected, and that is common. He then palpates the area, looks at the eyes at rest and in expression, including a full smile, and marks where the concern is. Only then is ultrasound used to confirm what is there: whether the material looks like hyaluronic acid or something else, how deep it sits, whether it is one deposit or several small pockets, and where the nearby vessels run.

That order matters. A lump and the swelling around it are often in different places, and the material that is causing a problem may not be where the patient points. Ultrasound-guided hyaluronidase, described in the dermatology literature since at least 2016 (Quezada-Gaón and Wortsman, JEADV 2016), lets the enzyme be placed into the deposit rather than around it.

“More filler cannot fix a face that already has too much filler.”

Correcting a hyaluronic acid lump

Hyaluronic acid filler can be broken down by hyaluronidase, an enzyme injected into the filler. For non-urgent correction, published guidance recommends a small skin test dose first, treating to effect rather than to a fixed dose, reassessing after about 48 hours, and waiting at least two weeks before any further filler is considered (King, J Clin Aesthet Dermatol 2018; Murray, J Clin Aesthet Dermatol 2021). Suspected filler in a blood vessel is different: it is treated immediately with high doses, without waiting for a test. Under the eye, the aim is selective: dissolve the deposit that is causing the lump or tint, not every trace of filler in the face.

Complete removal is not always possible in one round, particularly when filler has broken into many small pockets or has been layered over several years by different injectors. MRI studies have found hyaluronic acid filler still present in the mid-face years after injection, including in patients who had not been treated for more than five years (Master, PRS Global Open 2024), and periocular filler has been documented causing swelling up to nine years later (Chang, Ophthalmic Plast Reconstr Surg 2017). That is why old filler can be the explanation for new puffiness.

When the lump is not hyaluronic acid

Sculptra (poly-L-lactic acid), Radiesse (calcium hydroxylapatite), Ellansé (polycaprolactone) and Juvelook are not dissolved by hyaluronidase. Lumps from these need a different plan, and nobody can honestly promise to “dissolve” them. In a review of 5,081 calcium hydroxylapatite treatments, 3% had an adverse event and 96% of those were nodules, most of which resolved (Kadouch, J Cosmet Dermatol 2017). Published options for persistent non-HA nodules range from waiting, to intralesional steroid with or without 5-fluorouracil, to excision as a last resort (Lemperle, Plast Reconstr Surg 2009; Vleggaar, J Drugs Dermatol 2014).

For excess or layered collagen-stimulator material, including under the eye, Dr Sin Yong uses the Sculpting mode of Time Freeze Laser LCLR®, which is built to break up and take away the excess; he uses it for Ellansé nodules, excess Juvelook, layered hyaluronic acid and migrated Sculptra. He uses it under the eye as well as elsewhere in the face; whether it suits a particular under-eye is decided at assessment, after ultrasound. More on this: lumps after Sculptra, Radiesse, Ellansé or Juvelook under the eye.

Delayed nodules months or years later

A new, firm or tender nodule appearing months or years after filler is a different problem from a lump in the first weeks. It may be an inflammatory reaction, a low-grade infection on the surface of the filler (biofilm) or a foreign-body granuloma (Signorini 2016; Urdiales-Gálvez, Aesthetic Plast Surg 2018). A 2021 review argued that “delayed-onset nodule” is a symptom rather than a diagnosis and that tests such as ultrasound, inflammatory markers and sometimes histology should guide treatment rather than a sequence of guesses (Convery, J Clin Aesthet Dermatol 2021); published algorithms take the same staged approach (Snozzi and van Loghem, PRS Global Open 2018). These are assessed before anything is injected.

Puffiness and swelling rather than a lump

Puffiness below the eye after filler is often malar oedema: fluid collecting in a compartment between the orbicularis retaining ligament and the zygomaticocutaneous ligament, where lymphatic drainage is poor. Recent expert recommendations list high filler volume and placement above the malar septum among the risk factors (Baranska-Rybak, Dermatol Ther 2026). Retained filler can also produce a late “pale puffy lower eyelid pillow” that is easily mistaken for festoons; one report described correction with hyaluronidase followed by fractional CO₂ laser for the remaining laxity (Lederhandler, J Drugs Dermatol 2021). More on this: under-eye filler swelling and puffiness. The bluish tint is covered on the Tyndall effect after filler.

What not to do

• Do not add more filler on top of a lump or a puffy area to “balance” it.
• Do not massage hard or repeatedly unless the injecting doctor has asked you to, for a specific reason.
• Do not accept steroid injections into a lump before anyone has established what it is.
• Do not use home “filler dissolving” devices or products bought online.

After correction

Once a lump has been dissolved or settled, the area is reassessed after swelling has gone down. Many people decide they do not want filler under the eye again, and for some eyes that is the right answer: a true fat bag, thin crepey skin and pigment are not filler problems, as set out on when not to have tear trough filler. Where a hollow remains and refilling is appropriate, less product, placed deeper, is the usual principle. Fees follow the plan and are set out in writing; how fees are quoted explains why they are not published.
