Why Malar Bags After Filler Happen and How To Fix Them

Daniel Ezra, 22 February 2026

Dermal filler treatments have become increasingly popular for facial rejuvenation, particularly in the midface and under-eye area. However, when not performed with proper anatomical understanding, these procedures can sometimes lead to unwanted complications, including malar bags. Understanding why this occurs and what can be done about it is essential for anyone considering or experiencing issues with facial filler treatments.

In this article, we will explore the causes of malar bags after filler, how they differ from typical under-eye puffiness, and the specialist treatment options available to address this concern.

What Are Malar Bags and How Are They Different from Typical Under-Eye Puffiness

Malar bags are a specific type of facial swelling that appears lower and more laterally positioned than typical under-eye puffiness. Rather than sitting directly beneath the lower eyelid, malar bags develop over the upper cheek area, known as the malar region. This distinctive positioning is one of the key features that sets them apart from standard under-eye bags.

The term malar bags refers to three different issues that can be difficult to differentiate. Our specialists at the Ezra Clinic are experts in this area and can help you understand these issues and how best to treat them.

  • Malar mounds describe a mound-like swelling in the upper outer cheek area. This is a constant feature and does not change. It is due to a complex interaction of ligaments and areas of fat loss around the cheek. It is often associated with the mid-cheek groove, which is a hollow running diagonally from the inner corner of the eye in a downward and outward direction.
  • Malar oedema is a similar feature, but where fluid accumulation is a key feature. This is characterised by fluctuations in bag size, which are typically worse in the morning.
  • Festoons represent a more advanced or chronic form of malar swelling. These are often associated with lax, folded skin that creates a characteristic draped appearance over the cheek.

Festoons can be particularly challenging to treat and may worsen over time.
The fundamental difference between malar bags and classic under-eye bags lies in their underlying causes. Traditional under-eye bags typically result from fat prolapse, in which the orbital fat pads protrude through weakened structures around the eye. In contrast, malar bags are primarily caused by fluid retention, ligament laxity, and specific anatomical factors rather than fat displacement alone. This distinction is crucial because it determines which treatment approaches will be effective and which may actually worsen the condition.

Why Do Malar Bags Occur After Filler?

The development of malar bags following filler treatment can be attributed to several interconnected factors, all related to how injectable products interact with the delicate anatomy of the midface.

One of the primary mechanisms involves the impact of filler on lymphatic drainage. The lymphatic system plays a vital role in removing excess fluid from facial tissues. When excessive amounts of hyaluronic acid filler are placed in the midface or when filler is positioned incorrectly, it can physically obstruct the normal flow of lymphatic fluid. This obstruction leads to persistent malar oedema, as fluid accumulates in the tissue with nowhere to drain effectively.

The hydrophilic properties of hyaluronic acid fillers further compound this issue. Hyaluronic acid can attract and bind water molecules, which is one of its beneficial properties in appropriate circumstances. However, certain hyaluronic acid products are particularly hydrophilic, and in susceptible patients, this characteristic can significantly worsen swelling. The filler essentially acts like a sponge, drawing water into an area where drainage is already compromised.

The risk of developing malar bags increases substantially with overfilling, inappropriate injection technique, or poor patient selection. When too much product is placed in the midface, when it is injected too superficially or in the wrong anatomical plane, or when patients with pre-existing tendencies towards fluid retention receive filler, the likelihood of complications rises dramatically.

How Filler Can Be Corrected When It Causes Malar Bags

When hyaluronic acid filler is identified as the cause of malar bags, effective correction strategies are available. The most reliable approach involves ultrasound-guided assessment followed by gradual dissolving of the problematic filler. Ultrasound imaging allows practitioners to visualise exactly where the filler has been placed and how much product has been injected, enabling precise, targeted treatment.

Hyaluronidase, an enzyme that breaks down hyaluronic acid, is used to dissolve excess filler in a controlled and staged manner. This gradual approach is important because dissolving too much filler too quickly can lead to other aesthetic concerns or complications. The process may require multiple sessions to achieve optimal results whilst maintaining facial balance and symmetry.

However, it is important to note that correction options are significantly limited if non-hyaluronic acid fillers are used. Products such as calcium-based fillers or biostimulatory substances, such as poly-L-lactic acid, cannot be dissolved with hyaluronidase. In these cases, patients may need to wait for the product to break down naturally over time or require more invasive intervention.

When Filler Is Not the Right Solution

In many cases, particularly for patients with pre-existing malar bags or festoons, filler treatment is contraindicated from the outset. Adding volume to an area already experiencing swelling and fluid retention will almost inevitably worsen the condition and further distort facial contours.

Whilst filler might temporarily camouflage the issue by smoothing the junction between the swollen area and surrounding tissue, this approach does not address the underlying anatomical and functional causes of malar bags. In fact, it often exacerbates the problem by adding more hydrophilic material to an area with compromised lymphatic drainage, creating a cycle of worsening oedema.

Reducing the Risk of Malar Bags After Filler

Prevention is always preferable to correction when it comes to filler complications. Reducing the risk of developing malar bags begins with a thorough consultation and comprehensive anatomical assessment before any treatment is undertaken. Practitioners should evaluate facial anatomy, skin quality, tendencies toward fluid retention, and any pre-existing signs of malar swelling or festoons.

Conservative product selection, using low volumes, and ensuring precise placement are all critical factors in minimising risk. Choosing less hydrophilic hyaluronic acid formulations and injecting in the correct anatomical plane at appropriate depths can significantly reduce the likelihood of complications.

Perhaps most importantly, practitioners should prioritise alternative treatments in patients who are prone to fluid retention or who show early signs of malar swelling. For these individuals, the risks of midface filler treatment simply outweigh the potential benefits.

Festoons and Malar Bags Treatment – Specialist Options

For patients experiencing malar bags or festoons, whether related to filler or occurring independently, there are several specialist treatment approaches available. These strategies focus on addressing the underlying structural and functional issues rather than simply adding volume.

Non-Surgical and Minimally Invasive Options

For patients seeking alternatives to surgery, several non-surgical and minimally invasive treatments can help improve malar bags and festoons.

Radiofrequency and Microneedling

Radiofrequency treatments combined with microneedling offer skin tightening and collagen stimulation benefits that can improve tissue quality and support better lymphatic drainage. These technologies work by delivering controlled energy to the deeper layers of skin, triggering the body’s natural healing response and promoting the production of new collagen and elastin fibres.

The Ezra Clinic Insight: At The Ezra Clinic, we have developed particular expertise in combining these approaches with filler dissolution. In some cases, dissolving problematic filler is essential. Following a consultation with your practitioner, they may suggest using Topilase with microneedling to resolve the problem effectively and safely.

CO2 Laser Resurfacing

CO2 laser resurfacing represents another targeted energy-based treatment option aimed at tightening lax skin and improving the overall quality of tissue in the malar region. This treatment works by creating controlled micro-injuries in the skin, which stimulates comprehensive tissue remodelling and can help reduce the appearance of festoons and malar bags over time.

These injections act to close down the spaces within which the fluid accumulates, thereby reducing the oedema.

Surgical Options

For more advanced cases of malar bags and festoons, surgical intervention may be the most effective solution. There are many surgical options available.

Blepharoplasty Combined with Midface Lift

This surgical approach addresses the structural laxity and weakened support that develops in the lower eyelid and cheek junction. By repositioning tissues and tightening supportive structures, this procedure can provide dramatic and long-lasting improvement. In selected cases, direct festoon excision may be required to remove excess, redundant tissue.

Dr Daniel Ezra brings extensive expertise to blepharoplasty surgeries, with a particular focus on achieving natural-looking results that respect the delicate anatomy of the eye and midface region.

Direct Excision of festoon

This is an excellent procedure for the right patient. We have also developed novel approaches to the procedure where we can perform blepharoplasty through the same incision as the festoon excision. We have achieved excellent results from this.
