Dark Circles & Vascular Shadowing: Treating Under-Eye Pigment with PRP and Hydrating Boosters
Introduction
Many people notice persistent dark colouring beneath their eyes and wonder whether it is simply a sign of tiredness, something related to their skin, or a reflection of deeper changes happening beneath the surface. Dark circles are one of the most commonly searched aesthetic concerns in the UK, and yet they are frequently misunderstood — in part because they are not always caused by the same thing.
This article explores what dark circles and vascular shadowing under the eyes actually are, why they develop, and what current non-surgical approaches — including platelet-rich plasma (PRP) and hydrating skin boosters — may offer as part of a treatment plan. It also explains the limitations of these approaches, the importance of identifying the underlying cause before considering any treatment, and when speaking to a qualified healthcare professional may be appropriate.
Understanding what is driving the discolouration is the essential first step, because the most suitable treatment — if any is appropriate — will depend heavily on individual anatomy, skin characteristics and medical history.

What treatments are available for dark circles under the eyes?
Dark circles under the eyes can have several causes, including vascular shadowing, melanin pigmentation, volume loss and skin thinning. Treatment depends on the underlying cause. Options may include PRP (platelet-rich plasma), hydrating skin boosters and, where appropriate, dermal fillers. Individual suitability must be assessed by a qualified healthcare professional before any treatment is considered.
What Are Dark Circles, and Why Do They Develop?
Dark circles under the eyes — sometimes called periorbital hyperpigmentation or periorbital discolouration — are not a single condition. The term describes the appearance of darkening beneath or around the lower eyelid, which can arise from several different anatomical and physiological causes.
Understanding the type of dark circle present is clinically important, because each cause may respond differently to treatment approaches.
Vascular Shadowing
One common cause is the visibility of blood vessels beneath the thin, delicate skin of the lower eyelid. The periorbital skin is some of the thinnest on the body, and as it becomes more transparent — either naturally with age or through reduced collagen — the underlying vasculature can become more visible, producing a bluish, purple or reddish hue. This is often described as vascular shadowing.
Melanin-Based Pigmentation
Some individuals have increased melanin deposition in the periorbital area, producing a brown or greyish discolouration. This type is more common in people with medium to darker skin tones and can have a genetic component. Sun exposure and post-inflammatory changes can also contribute.
Volume Loss and Structural Shadowing
As facial volume reduces with age, the under-eye area can develop a hollowed appearance, creating a shadow that reads as a dark circle despite not being caused by pigmentation at all. This is sometimes called a tear trough depression and is a structural rather than pigmentary concern.
Lifestyle and Contributing Factors
Sleep deprivation, dehydration, alcohol, smoking, allergies, rubbing the eyes and certain medical conditions can all worsen the appearance of under-eye discolouration. Addressing modifiable lifestyle factors is a reasonable first step before considering any aesthetic treatment.
The Role of Skin Structure and Ageing in the Periorbital Area
The skin around the eyes is structurally different from skin elsewhere on the face. It is thinner, has fewer sebaceous glands, is more prone to dehydration, and is subject to constant movement through blinking and expression. Over time, collagen and elastin — the structural proteins that give skin its firmness and resilience — naturally decline. This thinning can accelerate the visibility of underlying vascular structures and reduce the skin's ability to maintain hydration and a healthy barrier.
Depletion of hyaluronic acid — a naturally occurring molecule that retains water within the skin — contributes to reduced volume, fine lines and a dull, crepey texture in this area. These structural changes help explain why some patients find that skin quality-focused treatments, rather than purely pigment-targeting approaches, can be relevant to improving the overall appearance of the under-eye area.
Treatment Options for Dark Circles: What May Help and for Whom
There is no single treatment that addresses all types of dark circles, and no approach can guarantee a specific outcome. The following outlines some of the non-surgical options that qualified practitioners may consider, depending on the individual's presentation.
Platelet-Rich Plasma (PRP) for the Under-Eye Area
PRP is a treatment that uses a sample of the patient's own blood, which is processed to concentrate the platelets and their associated growth factors. The resulting plasma is then administered into or around the treatment area. In the periorbital area, PRP may be used with the aim of stimulating collagen production, improving skin quality and thickness, and potentially addressing some forms of discolouration associated with skin thinning.
It is important to note that the evidence base for PRP in the periorbital area is developing and results vary between individuals. PRP is not a treatment for structural volume loss and is unlikely to address deep tear trough hollowing on its own. Those interested in understanding more about PRP as a skin rejuvenation approach can find further information about PRP treatment options from a practitioner perspective.
Hydrating Skin Boosters
Skin booster treatments use small intradermal injections of hyaluronic acid formulated specifically for hydration rather than volumising. Unlike traditional dermal fillers, these products are designed to integrate into the skin, improving moisture retention, skin quality and luminosity.
In the periorbital area, skin boosters may help improve the texture, hydration and overall quality of thin or crepey skin. However, they are not designed to significantly lift or volumise the tear trough area, and their suitability depends on the individual's skin type, anatomy and the nature of their under-eye concern.
Those researching hydration-focused injectable approaches can explore further detail about skin booster treatment to understand how these treatments differ from other injectable options.
Profhilo
Profhilo is a specific type of injectable treatment using a high concentration of hyaluronic acid that is designed to stimulate collagen and elastin production and improve skin hydration. It is sometimes used to address skin quality in the periorbital and lower face area, though its use around the delicate under-eye region requires careful assessment and clinical expertise.
For those exploring skin quality improvements more broadly, further information about Profhilo treatment may help clarify what this approach involves and how it differs from conventional fillers.
Dermal Fillers for the Tear Trough
Where dark circles are primarily caused by structural volume loss and hollowing in the tear trough area, dermal fillers may sometimes be considered as an option. This is a technically demanding area, and the suitability, risk profile and likely outcomes depend heavily on the individual's anatomy, skin quality, and the experience of the treating practitioner.
Tear trough filler treatment carries specific risks, including swelling, bruising, the Tyndall effect (a bluish discolouration from superficially placed filler), and in rare cases, more serious vascular complications. It is not suitable for everyone, and a thorough individual assessment is essential before this option is considered.

Topical Skincare
Evidence-informed skincare ingredients — including vitamin C (ascorbic acid), niacinamide, retinoids, peptides and SPF — may help support skin quality, reduce melanin-based pigmentation over time and protect against further UV-related damage. Topical approaches are generally lower risk and can be an appropriate first-line measure, though results vary and topical products alone may have limited impact on vascular or structural dark circles.
Who May Be Suitable for Injectable Treatments in This Area?
Injectable treatments in the periorbital region are not appropriate for everyone. A qualified healthcare professional should assess:
- The underlying cause of the dark circles (vascular, pigmentary, structural or mixed)
- Skin type, quality and thickness
- Relevant medical history, including bleeding tendencies, allergies and any previous treatments to the area
- Current medications, including anticoagulants
- History of previous reactions to injectable treatments
- Realistic expectations and treatment goals
- Whether lifestyle factors should be addressed first
Injectable treatments in the periorbital area may not be appropriate for individuals who are pregnant or breastfeeding, those with active skin infections or inflammation in the area, or those with certain medical conditions that affect healing or clotting.
When Should You Speak to a Healthcare Professional?
Whilst dark circles are very commonly a cosmetic concern without an underlying medical cause, there are circumstances in which speaking to a GP or other healthcare professional is appropriate.
Consider seeking medical advice if you notice:
- Sudden or unexplained changes in skin colouration around the eyes
- Swelling, puffiness or fluid retention that is new or worsening
- Associated symptoms such as itching, watering eyes or nasal congestion (which may suggest allergy)
- Signs of infection or skin irritation around the eyes
- Discolouration that appears asymmetric or changes rapidly
- Any underlying health concerns you feel may be contributing
For those who have had a previous injectable treatment and notice unexpected swelling, pain, skin colour changes or visual disturbance, prompt medical assessment is important. Vascular complications following injectable treatments, whilst rare, require urgent attention. Those who have had injectable treatments to the face and notice visual changes or severe, worsening pain should seek urgent medical care.
If you are unsure whether dark circles have a medical cause or whether an aesthetic approach is appropriate, speaking to a GP first is a sensible step.
Choosing a Qualified Practitioner for Under-Eye Treatments
The periorbital area is considered a high-risk anatomical zone for injectable treatments due to the proximity of important vascular structures and the delicacy of the tissue. It is important to seek treatment only from an appropriately qualified, trained and experienced healthcare professional with specific knowledge of periorbital anatomy.
Before any treatment, a responsible practitioner should:
- Take a full medical history
- Conduct a thorough assessment of the area
- Explain the treatment, its limitations and its risks clearly
- Obtain informed consent
- Discuss what to expect during recovery
- Advise on aftercare
- Provide access to appropriate aftercare support if needed
Under the Botulinum Toxin and Cosmetic Fillers (Children) Act 2021, certain cosmetic procedures are restricted for under-18s. All patients should ensure they are receiving care from a practitioner who adheres to current UK professional guidance on aesthetic treatments.

Safety, Risks and Aftercare Considerations
No injectable treatment — including PRP or skin boosters — is entirely without risk. Common side effects in the periorbital area may include:
- Bruising and swelling (this area bruises readily due to its vascularity)
- Temporary redness or tenderness at injection sites
- Mild discomfort during treatment
Less common but more significant risks may include:
- Infection
- Allergic or hypersensitivity reactions
- Irregular distribution or visible product placement
- Vascular complications (rare but serious, particularly with dermal fillers)
- Skin necrosis in rare cases associated with vascular compromise
Aftercare guidance will vary depending on the specific treatment and the individual practitioner's protocols. Generally, patients may be advised to avoid strenuous activity, alcohol, sun exposure and makeup immediately following treatment. Following all aftercare advice from the treating practitioner and attending any recommended follow-up appointments is important.
Key Points to Remember
- Dark circles under the eyes are not a single condition — they may be caused by vascular shadowing, melanin pigmentation, structural volume loss or a combination of factors.
- Identifying the underlying cause is essential before considering any treatment, as different causes may require different approaches.
- PRP and hydrating skin boosters may help improve skin quality, thickness and luminosity in the periorbital area, but results vary and neither is a universal solution for all types of dark circles.
- The periorbital area carries specific anatomical risks for injectable treatments, and treatment should only be undertaken by an appropriately qualified healthcare professional following individual assessment.
- Lifestyle factors — including sleep, hydration, sun protection and skincare — are worth addressing regardless of whether any aesthetic treatment is considered.
- If dark circles are associated with other symptoms or unexplained changes, speaking to a GP before pursuing aesthetic treatment is a sensible and responsible step.
Frequently Asked Questions
Can PRP genuinely improve dark circles under the eyes?
PRP may help improve skin quality, thickness and overall appearance in the periorbital area by stimulating collagen and growth factor activity. For dark circles caused or worsened by thin, poor-quality skin, this may produce some improvement in some individuals. However, PRP is unlikely to significantly address purely structural causes such as deep volume loss, and its effect on melanin-based pigmentation is limited. Individual results vary, and a clinical assessment is needed to determine whether PRP is appropriate for your specific presentation.
Are skin boosters the same as dermal fillers?
No. Skin boosters and dermal fillers are different injectable products with different purposes. Skin boosters use hyaluronic acid formulated to improve hydration and skin quality within the dermis, rather than to add significant volume or structural change. Dermal fillers are designed to restore volume or alter contour. In the periorbital area, skin boosters may be used to improve texture and hydration, whilst fillers may sometimes be considered where structural hollowing is the primary concern. A practitioner can explain which approach, if any, is relevant to your situation.
Is tear trough filler safe?
Tear trough filler can be appropriate for some individuals, but it is one of the more technically demanding and risk-associated filler treatments due to the anatomy of the area. Risks include bruising, swelling, the Tyndall effect, vascular complications and, in rare cases, more serious adverse events. Suitability depends on individual anatomy, skin quality, medical history and the expertise of the practitioner. It is not suitable for everyone, and thorough assessment by an experienced, qualified practitioner is essential before this treatment is undertaken.
How many sessions of PRP might be needed for under-eye concerns?
Treatment protocols vary depending on the practitioner, the individual patient and the degree of concern being addressed. Some practitioners may recommend an initial course of two to three sessions, with maintenance sessions considered thereafter. There is no universally agreed protocol, and an individual plan should be discussed with the treating clinician based on your specific presentation and response to treatment.
Can dark circles be fully removed with aesthetic treatment?
Whilst some aesthetic treatments may meaningfully improve the appearance of dark circles for certain individuals, it is important to have realistic expectations. Dark circles often have multiple contributing factors, some of which are genetic or structural and may respond only partially — or not at all — to current non-surgical approaches. Treatment may improve the appearance rather than eliminate the concern entirely. Individual outcomes vary, and a qualified practitioner can help set realistic expectations following assessment.
When should I see my GP about dark circles rather than seeking an aesthetic treatment?
If your dark circles are accompanied by other symptoms — such as persistent swelling or puffiness, changes in the skin around the eyes, eye irritation, unexplained weight changes, fatigue or other systemic concerns — it is sensible to speak to your GP before pursuing aesthetic treatment. In most cases, dark circles are a cosmetic concern, but it is important to rule out any underlying medical contribution where relevant.
Conclusion
Dark circles and vascular shadowing under the eyes are among the most commonly encountered aesthetic concerns, but they are rarely straightforward. Because the discolouration can arise from multiple different causes — including skin transparency, blood vessel visibility, melanin pigmentation, volume loss or a combination — identifying the dominant contributing factor is the essential starting point for any discussion about treatment.
Approaches such as PRP and hydrating skin boosters may help improve skin quality and reduce the appearance of dark circles for some individuals, but neither represents a guaranteed solution, and both require a thorough individual assessment to determine suitability. The periorbital area is anatomically sensitive, and treatments here should only be performed by appropriately qualified and experienced healthcare professionals.
Whether any aesthetic treatment is appropriate depends on the individual's health, medical history, anatomy, skin characteristics, treatment goals and clinical circumstances, and should be determined following a proper professional assessment. If there is any uncertainty about the cause of under-eye discolouration or whether treatment is appropriate, speaking to a GP in the first instance remains a sensible and responsible step.
