Top 5 Things to Know About Volume Restoration Procedures for Under Eyes
Volume restoration using prescription-only products are sometimes used in the under eye area to address hollowing and shadowing. It is a very common concern for patients. However, this is a technically demanding region with a higher risk profile, and it is not typically my first-line approach for most patients.
A careful assessment is essential. Not all under-eye concerns are due to volume loss — factors such as fat prolapse, skin laxity, pigmentation, and light reflection often play a significant role, and these are not always improved with filler. In some cases, volume restoration may provide subtle improvement; in others, it may lead to suboptimal outcomes.
Key Takeaways
Candidate selection
Volume correction may have a role in carefully selected patients with mild under-eye hollowing and good skin quality. A detailed assessment is essential to distinguish true volume loss from other contributors such as fat prolapse, skin laxity, or pigmentation, which are often better managed with alternative approaches.
Doctor-led care
This is a high-risk anatomical area. A doctor-led consultation allows for appropriate assessment, treatment planning, and discussion of risks, benefits, and alternatives. If treatment is undertaken, it should be performed with a conservative, individualised approach and with access to appropriate management should complications arise.
Product selection
Product choice is critical in the under-eye region. Softer, lower-hydrophilic products are generally preferred to reduce the risk of swelling and irregularities in thin skin. Inappropriate product selection or placement can lead to persistent contour issues that may be difficult to correct.
Risks and aftercare
Common short-term effects include bruising, swelling, and irregularity, which often settle. However, this area carries a higher risk of longer-lasting complications, including persistent swelling or contour changes, and a very high risk of serious medical complications including tissue necrosis, blindness and stroke. Appropriate aftercare and follow-up are important, and patients have direct access to me if concerns arise.
Results and longevity
While initial improvements may be seen early, longevity can be variable. In some cases, these products may persist well beyond 2 years — particularly with repeated treatments in the same area or when products not suited to this region are used. For this reason, a cautious, staged approach is generally preferred, with ongoing review rather than assuming a fixed duration of effect.
1. What are under‑eye (tear‑trough) volume correction procedures and how do they work?
The tear trough is the junction between the lower eyelid and the upper cheek. The skin in this region is thin, and underlying structures — including muscle and fat compartments — contribute to contour and support. Changes in midface volume can alter this support, creating a hollow that casts a shadow. This often presents as “dark circles,” even when pigmentation is not the primary issue.
Volume correction may be used to address volume loss by supporting the tissue plane and softening the transition between the eyelid and cheek. These products are (largely) reversible - and in some situations can be adjusted or dissolved if required. In the under-eye area, careful product selection is important, as formulations with higher water attraction or excessive firmness can increase the risk of swelling or visible irregularities. I will go into more detail about this during your consultation - there’s more to it!
A range of prescription-only volume replacement products exist, with differing properties. Selection depends on individual anatomy, tissue quality, and treatment goals, with an emphasis on subtle support rather than volume augmentation in this region.
Longevity is variable. While some patients may notice improvement for many months, these products can persist beyond this — particularly with repeated treatments or where product selection and placement are not well matched to the area. Technique is critical: conservative volumes and appropriate depth of placement are used to reduce the risk of contour irregularities and unwanted surface changes. Review after treatment allows for reassessment and, if appropriate, staged refinement.
2. Who should be considered for volume correction for the under eye area?
Volume correction may have a role in selected patients with mild under-eye hollowing and relatively good skin quality. The aim is not to change eyelid shape, but to soften the transition between the lower eyelid and cheek and reduce shadowing in a controlled, subtle way. Where appropriate, treatment is approached conservatively and staged, with small initial volumes and reassessment over time.
Not all under-eye concerns are suitable for this procedure. In many patients, structural factors are the primary issue, and these are often better managed with alternative approaches. Findings that may suggest a need for specialist review include:
Significant skin laxity or excess skin that is unlikely to respond to volume replacement alone
Prominent fat prolapse causing visible bulging rather than hollowing
Eyelid malposition or a history of prior eyelid surgery that has altered anatomy
Marked asymmetry or more complex periocular anatomy
In these situations, I may recommend assessment by a plastic surgeon or oculoplastic surgeon to determine the most appropriate management. There are several excellent surgeons at Mayfair Specialist Centre where my clinic is located, so the referral process is easy.
Prior to any treatment, it is important to discuss relevant medical factors, including pregnancy or breastfeeding, autoimmune conditions, previous eye procedures, medication use, and any history of reactions to injectable products or bee sting anaphylaxis. This allows for appropriate risk assessment and planning.
A doctor-led consultation includes a focused clinical assessment, standardised photography, and a clear discussion of risks, alternatives, and expected outcomes before any treatment is considered.
3. What to expect during a doctor‑led procedure (Cosmenon approach), cost and aftercare
Your consultation begins with a focused, doctor-led assessment. This includes standardised photography, evaluation of facial proportions, and assessment of the tear trough and midface support. The aim is to determine whether under-eye volume correction is appropriate, or whether alternative or adjunctive treatments are more suitable. For instance, a better option may be to rejuvenate the overlying skin, making it healthier and thicker, giving it more ability to hold back fat pads and reduce the appearance of dark circles and pigmentation. A clear discussion of risks, benefits, and alternatives forms part of the consent process before any treatment is considered.
If proceeding, the skin is prepared and markings are made to guide placement. Treatment is typically conservative, often starting with small volumes and reassessment over time rather than aiming for full correction in a single session.
The procedure, gentle contouring, and initial assessment occur within the same appointment. Most sessions are an hour long, which gives the me and my patient time to complete the procedure safely. There is a mandatory and complimentary review at 2 weeks to assess how the product has settled and whether any refinement is appropriate.
In line with AHPRA regulations, I cannot discuss cost of treatment here. Perhaps in contrast to other providers, I do not charge per syringe or “per mL”. My fees are based on the area treated and the risk involved. You are paying for my time and expertise and direct access to me in the event of any concerns or complications.
Technique and safety considerations
Technique is tailored to individual anatomy. Product is generally placed in deeper tissue planes to reduce the risk of visible irregularities. Both needles and blunt cannulae can be used in clinical practice:
Needle: allows precise placement but involves multiple entry points and may carry a higher risk of vascular injury if not performed with appropriate technique.
Cannula: uses a blunt tip and fewer entry points, which may reduce bruising and lower the likelihood of penetrating a vessel, although it does not eliminate risk.
Vascular occlusion is a recognised, though uncommon, complication in this area. Neither technique is risk-free, and safety depends on careful patient selection, anatomical knowledge, conservative volumes, and the ability to recognise and manage complications promptly. A vascular occlusion in this area, though rare, can lead to significant injury including blindness and stroke.
Aftercare and Recovery
Swelling and bruising are common in the first few days and typically settle over 1–2 weeks. Post treatment advice may include avoiding strenuous exercise, heat exposure, and alcohol in the immediate post-treatment period, along with simple supportive measures such as head elevation and intermittent cooling if required.
Patients should seek prompt review if they experience concerning symptoms such as increasing pain, changes in vision, progressive redness, or unexpected asymmetry. All Cosmenon patients receive direct-access phone numbers to me in the event of any concerns.
Planning and Follow-up
A staged approach is generally preferred, with follow-up to reassess outcomes and determine whether further treatment is appropriate. Longevity and response vary, and ongoing review is important to maintain a conservative and balanced result.
Discussion points for consultation
A structured consultation should cover:
Suitability of volume-correction versus alternative treatments
Proposed product type and rationale for selection
Injection technique and associated risks
Availability of reversal agents and management pathways for complications
Expected course of recovery and follow-up arrangements
Realistic expectations based on individual anatomy
This approach prioritises safety, transparency, and appropriate treatment selection over routine or standardised intervention.
4. Risks, complications and how they are managed
Non-surgical volume replacement in the under-eye area can provide improvement in selected patients, but they are not without risk. Common short-term effects include bruising, swelling, redness, and temporary irregularity. These usually settle over several days to two weeks. Simple aftercare — such as intermittent cooling, head elevation, and avoiding strenuous activity in the first 48 hours — can help support recovery. Any concerns should be reviewed early so that appropriate advice or treatment can be provided. All of my patients receive Aftercare Instructions via email soon after their treatment consultation.
In some cases, product placed too superficially may lead to a visible bluish discolouration (often referred to as the Tyndall effect). This may improve over time, but can require correction. Persistent swelling in the lower eyelid or upper cheek can also occur, particularly in this anatomically sensitive area, and may need active management depending on severity and duration. Studies have shown that these products can cause blood vessel and lymphatic system compression, leading to prolonged swelling. Nerves can also be compressed, leading to chronic pain issues.
More significant complications, while uncommon, can occur. These include vascular compromise and, very rarely, visual disturbance. Symptoms such as increasing or disproportionate pain, changes in skin colour, or any visual symptoms require immediate medical assessment. Prompt recognition and management are critical.
Risk is reduced through careful patient selection, detailed anatomical knowledge, conservative technique, and appropriate follow-up. For this reason, I approach treatment in this area extremely cautiously, with a clear understanding of potential complications and a structured plan for review and management if required. More often than not, I encourage my patients to try topical and intra-dermal treatment combinations to improve the skin first. These treatments are significantly safer - so why not?
5. Results, longevity and how this compares with surgery
Results following under-eye volume correction can be seen early, although the degree and duration of improvement vary between individuals. With these products, changes may be maintained for many months. In some cases, the product can persist well beyond several years — particularly where repeated treatments have been performed in the same area or where product selection and placement are not well matched to the tissue.
Management of the under-eye area should be individualised. The choice between non-surgical and surgical options depends on anatomy, the underlying cause of concern, and patient preference after a detailed consultation.
Non-surgical volume replacement procedures (under-eye): A non-surgical option with minimal downtime and reversibility. It may be considered in selected patients with true volume loss, although it is not appropriate for all presentations and is approached conservatively.
Fat grafting: A surgical procedure that uses transferred tissue to restore volume. It may provide longer-lasting change, but involves variable graft survival and a more involved recovery.
Lower blepharoplasty: A surgical approach that addresses excess skin and fat prolapse directly. It offers the most definitive structural correction, but with greater recovery time and operative risk.
Where concerns are primarily structural — such as significant skin laxity or fat prolapse — surgical options are often more appropriate. In these situations, referral for specialist assessment can be arranged.
For patients with suitable anatomy, non-surgical treatment may be considered as part of a staged plan, with ongoing review rather than assuming a fixed duration of effect.
