Malar bags (festoon): why filling can make them worse
The malar bag is one of those findings that change the whole plan. The patient comes in asking to "remove the bag" or "fill the dark circle," and the bulge they point to is in the upper cheek, below the eyelid. Injecting there, or right next to it, usually makes the bag bigger. Knowing how to recognize the picture is what avoids one of the most frustrating complications of the periorbital region: swelling that does not go away.
This guide is about assessment. It gives no technique, volumes or plans, which are the decision of the qualified professional, according to the product's instructions for use and the rules of their professional council in Brazil.
What is a malar bag and what is festoon?
The literature uses a few terms for bulges of the upper cheek, which do not always appear with the same definition:
| Term | What it describes | Main component |
|---|---|---|
| Malar edema | Soft swelling that varies during the day | Accumulated fluid |
| Malar bag (malar mound) | Bulge over the malar eminence, below the palpebromalar groove | Chronic edema and tissue change |
| Festoon | Folds of lax skin and muscle, in a "curtain" or in layers | Laxity of skin and of the orbicularis oculi muscle, with or without edema |
In practice, the components overlap: a festoon may have edema underneath, and an old malar bag often comes with skin changed by photoaging.
Why does the bag form there?
The area has an anatomical peculiarity. The prezygomatic space, over the zygomatic bone and below the orbicularis muscle, is bounded above by the orbicular retaining ligament and below by the zygomatic ligament. These boundaries act as a barrier to fluid flow, and lymphatic drainage in the area is considered slower. When fluid enters this compartment, it tends to stay.
Factors described as associated:
- Aging and laxity of skin and muscle.
- Chronic sun exposure, which alters skin quality.
- Fluid retention: salt, alcohol, poor sleep, allergies, menstrual cycle.
- Health conditions: thyroid, kidney and heart diseases, chronic allergies and some inflammatory skin diseases.
- Smoking.
- Family predisposition.
- Previous filler in the area, even old.
How to tell it from eyelid bags and the tear trough?
| Finding | Where it is | How it behaves |
|---|---|---|
| Eyelid fat bags | Lower eyelid, above the palpebromalar groove | Increase on upward gaze; do not vary much during the day |
| Structural tear trough | Depression in the tear trough | Shadow, not a bulge; improves with frontal light |
| Malar edema | Below the palpebromalar groove, over the malar eminence | Worse on waking, improves during the day |
| Festoon | Same area, in folds | More evident when smiling or contracting the orbicularis |
The full assessment of dark circles is in under-eye circles: types and assessment, and the set of signs of a "tired look" in tired look: assessment.
Which tests help at the consultation?
- Variation during the day. Ask whether the bag is bigger in the morning. Ask for photos taken at home right after waking and at the end of the day.
- Orbicularis contraction. Ask the patient to squeeze the eyes shut or smile hard. A festoon, with a muscular component, usually becomes more evident.
- Looking up. Eyelid bags increase; a malar bag changes little.
- Gentle palpation. Edema is soft and pits; lax skin forms folds when pinched.
- Frontal light and overhead light. Overhead light accentuates reliefs and shadows; frontal light separates shadow from bulge.
- Filler history. Ask about any procedure in the area, including years ago and elsewhere. See patient with unknown previous filler.
Why can filling make it worse?
Hyaluronic acid attracts and retains water, a property described as hydrophilia. Placed in the tear trough, the lower eyelid or the upper cheek of a patient with a malar bag, the gel adds its own volume to the water it attracts, in a compartment that already drains poorly. The most described result is an increased bulge and persistent swelling, sometimes months later. See late swelling after hyaluronic acid.
Even cheekbone filler in a deep plane, which is sometimes proposed to "give support" to the bag, requires great caution in these patients, because it can compress drainage or displace product into the superficial compartment.
Which paths are usually considered?
| Situation | Path usually considered |
|---|---|
| Swelling that varies during the day | Investigate and control retention factors; medical assessment when indicated |
| Bag linked to previous filler | Assess breaking down the product, when it is hyaluronic acid |
| Photoaged skin with mild laxity | Photoprotection and skin-quality technologies, as indicated |
| Established festoon, with folds | Surgical assessment (eyelid and malar surgery) |
| Evident muscular component | Specialist assessment; toxin in the area has a restricted role and a risk of worsening closure or drainage |
In many cases, the best HOF approach is to treat other areas of the plan and leave the bag to whoever treats the cause.
What are the most common mistakes?
- Calling everything a dark circle. Shadow, eyelid bag and malar bag call for different approaches.
- Assessing only at the appointment time. A bag from edema may be minimal in the afternoon and evident in the morning.
- Not asking about old filler. Product placed years ago may be behind the swelling.
- Filling the tear trough to "disguise" the bag. The shadow may decrease for a few days and the bulge increase afterward.
- Promising that the bag will disappear with some injectable. An honest expectation is the best investment in the relationship with the patient.
How to explain it to the patient
Explaining why you will not inject increases trust: the patient sees that the recommendation comes from the assessment, not from what they asked for. Record the guidance in the patient record.
And in Harmy?
Malar bag assessment checklist
- Malar bag, festoon, eyelid bag and dark circle differentiated and recorded.
- Variation during the day and retention factors asked about.
- History of filler in the area, from any time, investigated.
- Warning signs of systemic disease observed and referred.
- Photos with frontal and overhead light, at rest and with orbicularis contraction.
- Filling of the tear trough, lower eyelid and upper cheekbone reassessed in light of the bag.
- Guidance and patient decision recorded in the patient record.
Frequently asked questions
What is a malar bag?
It is a bulge in the upper cheek, below the lower eyelid and above the cheekbone. It can be formed by accumulated swelling, by laxity of skin and muscle, or by both. When there are layered skin folds, it is usually called festoon.
Does filler solve a malar bag?
Generally not, and it can make it worse. Hyaluronic acid attracts water, and the area has limited drainage; filling just below a malar bag tends to increase the swelling. A malar bag is considered a relative contraindication to filler in the area.
What is the difference between a malar bag and an eyelid bag?
An eyelid bag is on the lower eyelid, above the groove that separates eyelid from cheek, and is formed by orbital fat. A malar bag is below that groove, over the upper cheek, and is formed by swelling and laxity of the tissues in the area.
Can festoon be treated?
There are options that depend on the cause: control of factors that worsen swelling, investigation of associated diseases, skin-quality technologies and, in established festoons, surgery. Injectables have a limited role and require great caution.
