PRF Under-Eye Treatment London
If you are researching treatments for dark circles, hollow tear troughs or tired-looking eyes, you have probably encountered an overwhelming range of options. Dermal fillers, polynucleotides, PRP, PRF, laser treatments and surgery are all promoted as solutions, yet each addresses different concerns and produces different outcomes.
Platelet-Rich Fibrin (PRF) has emerged as one of the most exciting regenerative treatments available because it uses your own blood to stimulate tissue repair rather than simply adding volume. Unlike traditional fillers, PRF aims to improve the quality of the skin itself by encouraging collagen production, supporting microcirculation and enhancing the skin’s natural regenerative processes.
At NAR London, PRF under-eye treatment is one of our signature regenerative procedures. Our philosophy is simple: whenever appropriate, we aim to improve the health of the tissue rather than merely disguising the problem.
This guide explains everything you should know before considering treatment.

Understanding Dark Circles
One of the biggest misconceptions is that all dark circles are the same.
In reality, there are several different causes:
- Thin translucent skin
- Loss of collagen
- Volume loss within the tear trough
- Prominent blood vessels
- Hyperpigmentation
- Genetics
- Allergies
- Chronic rubbing
- Age-related fat redistribution
- Lifestyle factors including smoking and sun exposure
Many patients have more than one contributing factor. A personalised assessment is therefore essential before recommending any treatment.
Why the Under-Eye Area Ages Faster?
The skin beneath the eyes is among the thinnest anywhere on the body. As collagen production naturally declines with age, this area becomes increasingly transparent, allowing underlying blood vessels and muscles to become more visible.
At the same time:
- collagen production decreases
- elastin fibres weaken
- microcirculation changes
- supporting fat pads descend
- bone structure remodels with age
Together, these changes create hollows, fine lines and shadowing that many people describe simply as “dark circles”.
What Is Platelet-Rich Fibrin (PRF)?
Platelet-Rich Fibrin is a second-generation autologous regenerative treatment created from your own blood.
A small blood sample is collected and processed using a carefully controlled centrifugation protocol. Unlike PRP, PRF is prepared without anticoagulants, allowing a natural fibrin matrix to form.
The final preparation contains a concentration of naturally occurring platelets suspended within a fibrin scaffold together with white blood cells and signalling molecules that are released gradually over time.
Rather than functioning as a filler, PRF acts as a biological scaffold that supports tissue regeneration.
How Does PRF Work?
After treatment, platelets become activated and release naturally occurring growth factors involved in tissue repair.
These signalling molecules help support:
- collagen synthesis
- extracellular matrix remodelling
- tissue repair
- angiogenesis (formation of new blood vessels)
- improved skin quality
The fibrin matrix allows these signals to be released progressively rather than immediately, which is one of the features distinguishing PRF from conventional PRP.
It is important to note that individual responses vary, and PRF should not be viewed as a guaranteed substitute for surgery or fillers when significant volume loss is present.
PRF vs PRP
Although both treatments are prepared from your own blood, they differ in several important ways.
PRP contains a higher concentration of platelets suspended in plasma and is commonly prepared using anticoagulants.
PRF is produced without anticoagulants, resulting in a fibrin network that allows biological signals to be released more gradually.
In aesthetic medicine, PRF is frequently chosen where gradual tissue regeneration and skin quality improvement are the primary objectives.
What Can PRF Improve?
Patients commonly seek treatment for:
- tired-looking eyes
- early tear trough hollowing
- crepey skin
- fine lines
- reduced skin quality
- mild dark circles related to skin thinning
- early ageing
Patients with severe structural hollows or significant excess skin may require alternative or combined treatments.
What Happens During PRF Treatment?
Treatment begins with a consultation to determine whether PRF is suitable.
A small sample of blood is collected from your arm.
The sample is immediately processed using a medical centrifuge according to a carefully controlled protocol.
Once prepared, the PRF is precisely injected into carefully selected areas beneath the eyes using techniques designed to maximise safety and achieve natural-looking improvement.
The entire appointment generally takes around 45-60 minutes.
PRF Under-Eyes Recovery
Most patients experience minimal downtime.
Common temporary effects include:
- swelling
- redness
- bruising
- tenderness
These usually improve over several days.
Patients are generally advised to avoid strenuous exercise, alcohol and excessive heat for the first 24 hours.
Specific aftercare instructions should always be followed.
PRF Results Timeline
Day 1-3
Mild swelling or bruising may be present.
Week 2-4
Early improvements in skin quality may begin to appear.
Month 2-3
Collagen remodelling becomes increasingly noticeable.
Month 6
Many patients appreciate continued improvement in skin texture and overall appearance.
Because PRF stimulates biological processes, results develop gradually rather than immediately.
Risks & Side Effects
PRF has an excellent safety profile because it is derived from the patient’s own blood.
Nevertheless, all injectable procedures carry potential risks.
These include:
- bruising
- swelling
- discomfort
- infection
- temporary asymmetry
- inadequate response
- need for further treatment
Choosing an experienced practitioner is essential to minimise risk.
PRF vs Dermal Fillers
Fillers provide immediate volume replacement.
PRF aims to improve tissue quality.
Patients with advanced volume loss may still benefit from fillers or surgery, whereas patients seeking a natural regenerative approach may prefer PRF.
These treatments are not direct competitors – they address different biological problems.
PRF vs Polynucleotides
Polynucleotides are bio-stimulatory injectable products designed to improve skin quality through different biological mechanisms.
PRF differs because it is entirely autologous, using the patient’s own blood rather than manufactured ingredients.
The most appropriate treatment depends on the patient’s anatomy, goals and clinical assessment.
Scientific Evidence
Current research suggests PRF may improve skin quality, collagen production and overall tissue regeneration in appropriately selected patients.
However, evidence remains an evolving field.
Large, high-quality randomised controlled trials are still limited, and outcomes vary between preparation methods, treatment protocols and patient characteristics.
For this reason, PRF should be viewed as a regenerative treatment with encouraging evidence rather than a guaranteed solution for every cause of dark circles.
The NAR LONDON Approach
Every patient undergoes an individual assessment before treatment.
Rather than recommending the same procedure for everyone, we identify the primary cause of the under-eye concern and develop an appropriate treatment plan.
Where appropriate, PRF Under-Eyes may be combined with other regenerative treatments to optimise long-term skin quality while maintaining natural facial harmony.
Our objective is not simply to make patients look younger, but to improve the health and resilience of the skin itself.
Frequently Asked Questions
Is PRF painful?
Most patients describe only mild discomfort. Topical anaesthetic may be used where appropriate.
How many sessions are usually recommended?
Many patients benefit from a course of three sessions spaced several weeks apart, although recommendations vary depending on individual assessment.
Is PRF permanent?
No. The biological effects develop gradually and maintenance treatments may be recommended over time.
Can PRF replace fillers?
Not always. PRF improves tissue quality but does not replace volume in the same way as dermal fillers.
Can PRF help hereditary dark circles?
It may improve skin quality and reduce the appearance of some hereditary dark circles caused by thin skin, but genetic pigmentation and skeletal anatomy may limit the degree of improvement.
Is PRF safe?
Because PRF is prepared from your own blood, the risk of allergic reaction is extremely low. As with any injectable treatment, other risks such as bruising or infection remain possible.
Summary
PRF under-eye treatment represents one of the most promising regenerative approaches for patients seeking gradual, natural improvement in skin quality beneath the eyes.
Rather than masking ageing with added volume, PRF works by supporting the body’s own regenerative processes.
Careful patient selection, realistic expectations and practitioner experience remain the most important factors in achieving successful outcomes.
