Periorbital Structural Support: Combining Tear Trough Fillers with Superficial PRP Growth Factors

The area beneath the eyes is one of the first regions of the face to show visible signs of ageing. Many patients describe a persistent look of tiredness, hollowness, or shadowing beneath the lower eyelids that does not improve with rest or skincare alone. These concerns often lead patients to research non-surgical options for periorbital rejuvenation — the technical term for addressing the area surrounding the eyes.

One approach that has gained clinical interest in recent years involves combining tear trough fillers (a form of dermal filler placed along the tear trough groove) with platelet-rich plasma (PRP), which delivers concentrated growth factors to support tissue quality and skin renewal in the superficial layers.

Understanding how these two treatments may work together — and what realistic expectations look like — is an important part of making an informed decision. This article provides an educational overview of the science behind periorbital structural support, what the combination approach involves, who may consider a professional assessment, and what to expect before, during, and after treatment. If you are still in the research stage, this guide on how practitioners assess under-eye concerns before treatment can provide helpful context.

Periorbital structural support using tear trough fillers and PRP growth factors is a combined aesthetic approach. Dermal filler addresses volume loss and hollowness beneath the eye, while PRP delivers concentrated growth factors to improve skin quality in the superficial periorbital layers. Treatment suitability must be assessed individually by a qualified practitioner.

The periorbital region — the area surrounding the eyes — is anatomically complex and particularly susceptible to the visible effects of ageing. Several factors contribute to changes in this area over time:

• Volume loss: The fat pads that naturally support the under-eye region diminish with age, creating a hollow or sunken appearance along the tear trough groove — the natural junction between the lower eyelid and the cheek.
• Skin thinning: The skin beneath the eyes is among the thinnest on the face, making it more vulnerable to the breakdown of collagen and elastin over time.
• Vascular visibility: As the skin thins and volume is lost, underlying blood vessels may become more visible, contributing to a shadowed or dark-circle appearance.
• Ligamentous laxity: The supportive ligaments anchoring the eyelid to underlying structures can relax, altering the shape and position of the lower eyelid.
• Fluid accumulation: Lymphatic changes and reduced tissue resilience can contribute to puffiness or under-eye bags in some individuals.

These changes may occur at different rates depending on genetics, lifestyle, sun exposure, and other individual factors. No two patients will experience periorbital ageing identically, which is why individualised assessment is essential before any treatment consideration.

Tear trough fillers are a form of hyaluronic acid-based dermal filler placed along or beneath the tear trough groove, with the aim of restoring volume to the under-eye region and softening the appearance of hollowness or shadowing.

Hyaluronic acid (HA) is a naturally occurring substance found throughout the body, including in skin tissue. In filler form, it is cross-linked to create a gel-like consistency that can support tissue structure and add volume in targeted areas. When placed carefully in the periorbital region by an experienced practitioner, HA filler may help to:

• Soften the appearance of the tear trough groove
• Reduce visible shadowing caused by hollowness
• Support the structural transition between the lower eyelid and cheek
• Improve the overall contour of the mid-face and under-eye area

It is important to note that tear trough treatment is considered one of the more technically demanding areas for filler placement due to the delicate anatomy involved. The region has a high vascularity, the skin is particularly thin, and incorrect placement carries a risk of complications including bruising, swelling, and in rare but serious cases, vascular events.

Tear trough filler is not appropriate for everyone. Patients with significant lower eyelid laxity, prominent under-eye bags caused by fat prolapse, or certain medical conditions may not be suitable candidates, and this must be determined through thorough clinical assessment.

Platelet-rich plasma (PRP) is derived from the patient's own blood. A small blood sample is taken, processed through centrifugation to concentrate the platelets, and the resulting platelet-rich fraction is then applied or injected into the target area.

Platelets contain alpha granules that release a variety of growth factors — signalling proteins that play a role in tissue repair, cellular regeneration, and collagen stimulation. Key growth factors present in PRP include:

• Platelet-Derived Growth Factor (PDGF): Involved in cell proliferation and tissue repair
• Transforming Growth Factor Beta (TGF-β): Plays a role in collagen synthesis and extracellular matrix remodelling
• Vascular Endothelial Growth Factor (VEGF): Supports microvascular health and tissue perfusion
• Epidermal Growth Factor (EGF): Involved in skin cell renewal and epithelial repair
• Insulin-Like Growth Factor (IGF): Contributes to collagen and elastin production

When applied superficially to the periorbital area — through micro-needling, superficial injection, or topical application following a skin preparation technique — PRP growth factors may help to improve skin texture, hydration, fine lines, and overall skin quality in the under-eye region.

As an autologous treatment (using the patient's own biological material), PRP has a generally favourable safety profile in the context of allergic reactions, though it is not without risks and is not appropriate for all patients.

The rationale for combining tear trough fillers with PRP growth factors lies in addressing the periorbital region at two distinct anatomical levels — structural and cellular.

Structural support via hyaluronic acid filler operates primarily at a deeper tissue level. The filler physically replaces lost volume, lifts soft tissue, and restores the smooth contour between the lower eyelid and cheek. It provides an immediate, visible improvement in the structural framework of the under-eye area.

Superficial PRP application operates at a cellular and extracellular matrix level. The growth factors released from platelets interact with fibroblasts (the cells responsible for producing collagen and elastin), stimulating regenerative activity in the superficial dermis and subdermal layers. The result, over time, may be an improvement in skin quality, texture, and resilience.

By addressing both volume loss (structural) and skin quality (cellular), the combined approach aims to treat the periorbital region more comprehensively than either treatment alone might achieve.

The timing, sequencing, and delivery method of each treatment element should be carefully planned by the treating practitioner. Some clinicians perform both treatments in the same session; others prefer to separate them to allow an accurate assessment of each treatment's individual contribution and to minimise cumulative trauma to the tissue.

The evidence base for this combined approach continues to develop. Patients should have an informed discussion with their practitioner about the current level of clinical evidence supporting any combined protocol.

A professional consultation may be worth considering for individuals who:

• Notice a persistent hollowness or sunken appearance beneath the eyes that does not improve with rest or topical skincare
• Experience visible shadowing or darkening in the tear trough area related to volume loss rather than pigmentation
• Observe fine lines, skin crepiness, or textural changes in the periorbital skin
• Have experienced gradual changes to the under-eye area that they would like to understand better
• Are curious about non-surgical options available for periorbital concerns
• Are considering multiple treatment options and would benefit from a thorough comparison guided by a clinical professional

A professional consultation does not commit a patient to any treatment. It is an opportunity to discuss concerns, receive an individualised assessment of the anatomy and skin, understand what may or may not be appropriate, and ask questions about available options.

It is worth noting that not all under-eye concerns are attributable to volume loss or skin quality. Some presentations — including those caused by allergies, thyroid conditions, sleep disturbance, or structural factors such as prominent orbital rims — may not be appropriate for injectable treatment and may require different management strategies. A thorough consultation will help to identify the most appropriate path forward.

Tear trough filler and PRP treatments are typically performed in a clinical setting by a qualified aesthetic practitioner. While protocols may vary between clinics and practitioners, a typical combined periorbital appointment may involve:

Before treatment: A thorough consultation, medical history review, and facial assessment Informed consent discussion covering treatment goals, risks, limitations, and alternatives Photographs taken for clinical record-keeping Topical anaesthetic cream applied to the treatment area to improve comfort

During treatment: Blood drawn for PRP preparation and placed into the centrifuge while the filler treatment begins Tear trough filler placed using a fine needle or cannula (a blunt-tipped device), depending on practitioner preference and patient anatomy PRP applied to the superficial periorbital skin using micro-needling, superficial injection, or another appropriate delivery method The procedure typically takes between 45 and 90 minutes in total, depending on the complexity of the case

Immediately after treatment: Mild swelling, redness, and bruising are common and expected Patients are typically able to return home the same day Aftercare instructions are provided by the treating practitioner

Experiences vary between individuals. Any concerns following treatment should be communicated to the treating clinic promptly.

Aesthetic treatments for the periorbital area can produce meaningful improvements in many patients, but it is important to approach them with informed and realistic expectations.

Potential benefits that some patients may experience include: A softer, more refreshed appearance in the under-eye area Reduced hollowness or shadowing related to volume loss Improved skin texture and hydration in the periorbital region over subsequent weeks A more balanced transition between the lower eyelid and cheek

Important limitations and considerations: Results vary significantly between individuals depending on anatomy, skin quality, age, and lifestyle factors Tear trough filler does not address under-eye bags caused by fat prolapse; this may require surgical assessment PRP growth factor benefits are typically gradual, developing over weeks to months as collagen remodelling progresses Not everyone is a suitable candidate — contraindications include certain medical conditions, blood disorders, active infection, and pregnancy Multiple PRP sessions may be needed to achieve or maintain skin quality improvements Filler results are temporary; hyaluronic acid fillers are gradually metabolised by the body over time The combination approach requires careful clinical planning to minimise risks

No aesthetic treatment can completely reverse the ageing process or guarantee specific outcomes. Treatment suitability and expected results must be assessed on an individual basis.

Following any periorbital treatment, the treating practitioner will provide specific aftercare instructions tailored to the individual. General educational guidance for the post-treatment period may include:

• Avoid strenuous exercise for 24–48 hours following treatment to minimise swelling and bruising
• Avoid rubbing or applying pressure to the treated area, particularly in the initial 24–48 hours
• Keep the area clean and avoid applying heavy make-up immediately following treatment (follow practitioner guidance on exact timescales)
• Apply a cold compress gently if swelling or bruising occurs — avoid direct application of ice to the skin
• Stay well hydrated to support the body's natural recovery processes
• Apply broad-spectrum SPF 30 or higher daily, as UV exposure accelerates collagen degradation and may impair long-term results
• Use a gentle, hydrating skincare routine in the periorbital area, avoiding harsh actives such as retinoids or exfoliating acids until the skin has fully recovered (follow practitioner guidance)
• Attend any follow-up appointments recommended by the treating practitioner to review results and assess whether additional treatment is appropriate

Healthy lifestyle habits — including adequate sleep, a balanced diet, hydration, and avoidance of smoking — also contribute to overall skin health and may support the longevity of treatment outcomes.

Is tear trough filler suitable for everyone with under-eye concerns?

No. Tear trough filler is not appropriate for all patients or all types of under-eye concerns. Patients with significant lower eyelid laxity, prominent under-eye bags caused by fat prolapse, very thin or fragile skin, or certain medical conditions may not be suitable candidates. Additionally, some under-eye concerns — such as those caused by allergies, thyroid conditions, or structural anatomy — may not be appropriately addressed by filler. A thorough assessment by a qualified aesthetic practitioner is essential to determine whether filler is appropriate for your individual anatomy and concerns. You can also review who may not be suitable for under-eye filler before deciding.

How long do tear trough filler results typically last?

The longevity of tear trough filler varies between individuals and depends on factors including the specific filler product used, the volume placed, the individual's metabolism, lifestyle habits, and the anatomy of the treated area. Generally, hyaluronic acid fillers in the tear trough region may last anywhere from six months to eighteen months or longer in some patients before the material is gradually metabolised. Regular maintenance appointments may be recommended by the treating practitioner. Results cannot be guaranteed for a specific duration, and individual experiences will differ.

How many PRP sessions are typically needed for periorbital skin improvement?

The number of PRP sessions required varies depending on the individual's skin condition, age, treatment goals, and the specific protocol recommended by the practitioner. Some patients may notice gradual improvements after a single session, while others may benefit from a course of two to four treatments spaced several weeks apart. Maintenance sessions may also be recommended over time. PRP results develop gradually as growth factors stimulate collagen remodelling, meaning visible improvements in skin quality typically emerge over weeks to months rather than immediately. Your practitioner will advise on the most appropriate treatment plan following assessment.

What are the risks associated with tear trough filler?

Tear trough filler carries several potential risks that should be discussed thoroughly during a consultation. Common side effects include temporary swelling, bruising, tenderness, and redness at the injection site. Less commonly, patients may experience the Tyndall effect (a bluish discolouration caused by superficially placed filler), prolonged swelling, or nodule formation. In rare but serious cases, vascular complications — including inadvertent injection into or compression of a blood vessel — can occur, potentially affecting blood supply to surrounding tissues. This is why tear trough treatment should only be performed by an experienced, qualified practitioner in an appropriate clinical setting with access to emergency management protocols.

Can PRP and tear trough filler be performed in the same appointment?

Some practitioners perform both treatments in the same session, while others prefer to separate them. The decision depends on the individual patient's anatomy, treatment goals, and the practitioner's clinical judgement. Combining both in a single appointment may reduce the number of clinic visits required, but cumulative tissue trauma should be considered. Your treating practitioner will advise on the most appropriate sequencing and timing for your individual case. It is important to have an open discussion about the rationale behind the recommended treatment plan during your consultation.

Are there any contraindications to PRP treatment?

Yes. PRP treatment is not suitable for all patients. Contraindications may include active infections or skin conditions in the treatment area, blood disorders affecting platelet function, patients on anticoagulant medications (depending on specific circumstances), autoimmune conditions, pregnancy and breastfeeding, and certain cancers or medical conditions. A thorough medical history review is essential before PRP treatment is considered. Patients should disclose all current medications, supplements, and medical conditions during their consultation. For further information, you may wish to book a consultation at Pantaleo Clinic to discuss your individual suitability.

The periorbital region is one of the most anatomically delicate and aesthetically significant areas of the face. As volume loss, skin thinning, and tissue changes develop over time, many patients seek to understand their options for non-surgical periorbital rejuvenation.

The combination of tear trough fillers and superficial PRP growth factors represents a clinically considered approach that aims to address the under-eye area at two distinct levels — structural volume restoration and biological skin quality improvement. By working both at the deeper tissue layer and within the superficial dermis, this combined strategy may offer a more comprehensive approach to periorbital concerns than either treatment in isolation.

However, this is not a universally appropriate treatment. The periorbital area is complex, the anatomy varies between individuals, and the risks associated with tear trough filler in particular require careful clinical management by an experienced practitioner. PRP, while generally well tolerated, also has its own considerations and contraindications.

If you are researching options for under-eye rejuvenation, the most important step is to arrange a professional assessment with a qualified aesthetic practitioner who can evaluate your anatomy, discuss your concerns, and advise on the most appropriate — and safe — course of action for you individually.

Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.
