PRP, PRF, Microneedling and Exosomes in London: The Science Behind Younger, Fresher, Glowing Skin

Your skin has a remarkable capacity to repair and regenerate itself. The aesthetic treatments that consistently produce the most natural-looking, long-lasting results are the ones that work with this biology rather than against it. PRP, PRF, microneedling, and PRP with exosomes are all built on this principle. They use your own body's growth factors, platelets, and cellular signals to stimulate genuine collagen production, improve skin texture and tone, and address concerns like fine lines, dullness, dark circles, and loss of volume. No synthetic fillers. No toxins. Just science-led regeneration.

At The PRP Clinic by The Wellness, our doctors assess your skin, your concerns, and your goals before recommending a treatment plan. Everything we offer is evidence-based, medically supervised, and tailored to you.

What These Treatments Actually Do

Before diving into each individual treatment, it helps to understand the shared science underneath them all.

Collagen is the structural protein that gives skin its firmness, plumpness, and elasticity. From our mid-twenties onwards, collagen production declines at a rate of approximately 1% per year. By the time we reach our forties, the cumulative loss becomes visible as fine lines, sagging, hollowing under the eyes, and skin that no longer bounces back the way it once did.

Growth factors are signalling proteins produced by platelets and other cells that trigger the body's repair and regeneration processes. They stimulate fibroblasts (the cells that produce collagen and elastin), promote new blood vessel formation, accelerate tissue healing, and improve cell turnover. PRP, PRF, and exosome-based treatments all work by delivering concentrated growth factors directly to the skin, essentially telling the tissue to behave younger than it is.

Microneedling works by creating thousands of controlled micro-injuries that trigger the skin's wound-healing cascade. The body responds by flooding the area with growth factors, platelets, and new collagen. The micro-channels created also allow topical treatments, including PRP, to penetrate far more deeply than they could on intact skin.

These treatments are complementary. Many patients benefit from combining them. Your doctor will advise on the best approach for your skin.

PRP Facial and PRP Under Eye Treatment

What PRP is

Platelet-rich plasma is produced from a small sample of your own blood. The blood is placed in a centrifuge and spun at high speed to separate its components. The resulting plasma layer, which is rich in platelets, is extracted and prepared for injection or topical application.

Platelets are best known for their role in blood clotting, but they also contain alpha granules packed with growth factors including platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-beta), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), and insulin-like growth factor (IGF-1). When these are concentrated and delivered to the skin, they trigger a significant regenerative response.

PRP contains approximately 3 to 5 times the concentration of growth factors found in normal blood. This concentration matters. It is what separates PRP from your baseline healing capacity.

What the evidence says

A 2019 systematic review published in the Journal of Cosmetic Dermatology reviewed 11 studies on PRP for facial rejuvenation and found consistent improvements in skin texture, elasticity, and hydration, with a strong safety profile. A 2023 meta-analysis in Aesthetic Plastic Surgery confirmed that PRP significantly reduces fine lines and improves overall skin quality compared to placebo. Multiple randomised controlled trials have also demonstrated PRP's effectiveness for improving acne scarring, stretch marks, and skin laxity.

PRP for the face

PRP is injected intradermally across the face using a fine needle or micro-cannula, or it is applied topically immediately after microneedling to maximise absorption. It targets the dermis directly, stimulating fibroblast activity, improving skin thickness, and promoting the production of new collagen and elastin. Patients typically notice improved skin glow and hydration within two to three weeks of the first session, with more significant structural improvements visible after a course of three treatments spaced four to six weeks apart.

Results are gradual, which is part of what makes them look natural. This is not a filler that instantly puffs a wrinkle flat. It is a biological process that builds real collagen over time.

PRP for the under eye area

The skin under the eyes is the thinnest on the face, averaging around 0.5mm thick compared to 2mm elsewhere. This makes it particularly vulnerable to the signs of ageing and one of the first areas where patients notice change.

Dark circles have multiple causes. They may be vascular (visible blood vessels through thin skin), pigmentary (excess melanin), or structural (loss of volume creating shadowing). PRP addresses all three mechanisms by thickening the dermis, stimulating new collagen to reduce the transparency of the skin, and improving local circulation and lymphatic drainage. A 2019 study in the Journal of Cosmetic Dermatology demonstrated statistically significant improvement in periorbital dark circles following three PRP sessions, with patient satisfaction scores consistently high.

PRP under the eye also addresses fine lines, crepiness, and the hollowing that develops as the fat pad beneath the eye diminishes with age. For patients who are not ready for filler or prefer a natural approach, PRP is an outstanding first step.

Microneedling

What microneedling is

Microneedling uses a device fitted with multiple fine, sterile needles to create thousands of tiny punctures in the skin at a controlled depth. These micro-injuries are superficial enough to be safe but sufficient to activate the skin's healing response. In clinical settings, needle depths typically range from 0.5mm to 2.5mm depending on the area being treated and the concern being addressed.

The wound-healing cascade that follows involves three overlapping phases: inflammation (which recruits growth factors and signals repair), proliferation (during which fibroblasts produce new collagen and elastin), and remodelling (during which the new collagen matures and organises). The result, over weeks and months, is visibly firmer, smoother, more even skin.

What the evidence says

Microneedling has one of the strongest evidence bases of any minimally invasive aesthetic procedure. A 2016 systematic review in the Journal of Clinical and Aesthetic Dermatology reviewed 22 studies and concluded that microneedling is safe and effective for acne scars, fine lines, skin laxity, and hyperpigmentation. A 2021 randomised controlled trial in the International Journal of Dermatology confirmed that microneedling significantly improves skin texture and increases dermal collagen density as measured on histological analysis. Real, measurable, structural change.

What microneedling treats

Microneedling is particularly effective for fine lines and wrinkles, enlarged pores, uneven skin texture, acne and surgical scarring, hyperpigmentation and uneven tone, stretch marks, and general loss of radiance. It works across all skin types and tones, including darker skin tones where some laser treatments carry a risk of post-inflammatory hyperpigmentation. This makes it one of the most inclusive and accessible skin treatments available.

What to expect

A topical anaesthetic cream is applied before treatment to maximise comfort. The procedure itself typically takes 30 to 45 minutes. Immediately afterwards the skin appears red and may feel warm, similar to mild sunburn. This usually settles within 24 to 48 hours. Social downtime is minimal compared to more aggressive laser resurfacing. Most patients need a course of three to six sessions to achieve their best results, spaced three to four weeks apart.

Microneedling combined with PRP

When PRP is applied to the skin immediately following microneedling, the micro-channels allow the growth factors to penetrate far more deeply than they could on unbroken skin. This combination, sometimes called a regenerative facial, produces results that exceed either treatment alone. A 2018 split-face randomised controlled trial found that microneedling with PRP produced significantly greater improvement in acne scarring than microneedling alone. For patients seeking maximum skin rejuvenation, this combination is our most frequently recommended starting point.

PRF (Platelet-Rich Fibrin)

What PRF is and how it differs from PRP

PRF is the second generation of platelet concentrate technology, developed to address some of the limitations of standard PRP. The preparation process is similar in that your blood is drawn and centrifuged, but PRF is spun at a lower speed and without the anticoagulants used in PRP preparation.

The result is a fibrin matrix, a natural gel-like scaffold, within which platelets, leukocytes (white blood cells), and growth factors are embedded. This fibrin network is significant for two reasons. First, it allows for a slower, more sustained release of growth factors over a period of seven to ten days rather than the immediate release seen with PRP. Second, the fibrin scaffold itself acts as a three-dimensional support structure that can promote tissue regeneration and has a mild volumising effect when used as an injectable.

PRF also contains leukocytes, which play a role in immune regulation and anti-inflammatory signalling, and stem cell recruitment signals that are not present in standard PRP. The overall growth factor concentration in PRF is higher than in conventional PRP, and the sustained-release profile means that the biological effect continues for longer after the treatment.

What the evidence says

A 2020 study in the Journal of Cosmetic Dermatology demonstrated that injectable PRF produced significant improvements in skin quality, including hydration, elasticity, and roughness, after three sessions in patients with early signs of facial ageing. A 2021 comparative study found PRF superior to PRP for volume restoration under the eyes, attributed to its fibrin scaffold and longer growth factor release. Research into PRF continues to accelerate and the evidence base is growing rapidly.

Who PRF is best for

PRF is particularly well-suited to patients who want a more biological, filler-free approach to volume restoration. It is excellent for the under-eye area (tear trough), the mid-face, the nasolabial folds (smile lines), and the temples. It is also used in combination with microneedling in the same way as PRP, and many clinicians consider it a superior choice for skin rejuvenation due to its richer growth factor profile and fibrin scaffold.

Because PRF contains no artificial additives or anticoagulants, it is considered one of the most natural regenerative treatments currently available. Everything injected is derived entirely from your own blood.

PRP with Exosomes

What exosomes are

Exosomes are among the most exciting developments in regenerative medicine over the past decade. They are nano-sized extracellular vesicles, tiny bubbles released by cells, that act as messengers in the body's cellular communication network. They carry proteins, lipids, mRNA, and microRNA between cells, delivering instructions that regulate inflammation, tissue repair, stem cell activity, and gene expression.

In aesthetic medicine, exosomes derived from stem cells (typically mesenchymal stem cells sourced from umbilical cord tissue or other ethically obtained sources) are combined with PRP to create a treatment that addresses skin ageing at the cellular level. Where PRP supplies growth factors, exosomes supply the molecular signals that tell cells how to use those growth factors most effectively. The combination is synergistic.

What the evidence says

Exosome research is the frontier of regenerative science. A 2021 study in the International Journal of Molecular Sciences demonstrated that exosomes significantly enhanced skin cell proliferation, collagen synthesis, and wound healing compared to control groups. A 2022 review in Biomedicines identified exosome therapy as a highly promising approach for photoageing, hyperpigmentation, hair loss, and wound healing. Clinical studies combining PRP with exosomes are still emerging but early results are consistently positive, with patients reporting faster recovery, enhanced glow, and more pronounced improvements in skin quality than with PRP alone.

What PRP with exosomes treats

This combination is particularly well-suited to patients with significant photoageing (sun damage), uneven skin tone and pigmentation, fine lines and dullness that have not fully responded to standard PRP, and anyone seeking the most advanced regenerative treatment currently available. It is also increasingly used for hair loss (alopecia) and scalp health.

Because exosomes work at the level of gene expression and cellular communication, their effects are deeper and longer-lasting than growth factor stimulation alone. For patients who want the very best that regenerative skin medicine currently offers, PRP with exosomes represents the leading edge.

A note on sourcing

Not all exosome products are equivalent. At The PRP Clinic by The Wellness, we use only pharmaceutical-grade exosome preparations from regulated sources. Your doctor will explain the product used, its origin, and its evidence base before any treatment.

How to Choose the Right Treatment

Every skin is different. Age, skin type, lifestyle, concerns, and goals all influence which treatment or combination of treatments will give you the best outcome. Here is a general guide, though a consultation with our doctors will give you a personalised recommendation.

Microneedling is a strong starting point for most patients. It is excellent for texture, pores, fine lines, acne scars, and general radiance. It suits all skin tones and types.

Microneedling with PRP is ideal for patients who want to accelerate and enhance the results of microneedling, particularly for more significant signs of ageing, scarring, or dullness.

PRP alone (injected) is the treatment of choice for the under-eye area, particularly dark circles, hollowing, and crepey skin. It is also used as a full-face rejuvenation treatment via microinjections.

PRF is best for patients seeking volume restoration without filler, more sustained growth factor release, and the most natural possible biological approach. It is superior to PRP for the tear trough and areas requiring mild volumising.

PRP with exosomes is the most advanced option for patients with significant photoageing, persistent pigmentation, or those seeking the deepest level of cellular regeneration currently available. It is also ideal for patients who want maximum results from a single treatment course.

Combinations are common. Many patients benefit from microneedling with PRF, or injectable PRP under the eyes combined with a full-face PRF treatment. Your doctor will assess your skin and design a plan.

What to Expect Across All Treatments

Before treatment. Your doctor will conduct a thorough consultation, review your medical history, and assess your skin. A topical anaesthetic is applied to the face 30 to 45 minutes before treatment to minimise discomfort.

During treatment. Blood draw (for PRP and PRF) takes approximately 5 minutes. The centrifuge process takes 10 to 15 minutes. Treatment itself takes 30 to 60 minutes depending on the area and technique.

Immediately after. Redness, mild swelling, and warmth are normal and expected. Microneedling may cause pinpoint bleeding that resolves within minutes. Injection sites may show small bumps that settle within hours to days.

Recovery. Most patients return to normal activities within 24 to 48 hours. We advise avoiding make-up for 24 hours, sun exposure for 48 hours, and strenuous exercise for 24 hours post-treatment.

Results. Initial glow and hydration improvements are often visible within one to two weeks. Structural collagen improvements become most apparent at 6 to 12 weeks. Full results from a course of three sessions are typically seen at three to four months.

Maintenance. Most patients maintain their results with one to two treatments per year after an initial course.

Frequently Asked Questions

Are these treatments safe? PRP, PRF, and exosome treatments use materials derived from your own body, making allergic reactions extremely unlikely. Microneedling has an excellent safety record in clinical settings. All treatments are performed by medically trained practitioners at The PRP Clinic by The Wellness.

Do the treatments hurt? Topical anaesthetic is applied before all treatments. Microneedling is well-tolerated by most patients. Injections around the under-eye area are the most sensitive, but patients consistently report that the discomfort is manageable.

How many sessions will I need? For most patients, a course of three sessions spaced four to six weeks apart produces the best results. Some patients see significant improvement after a single session, particularly with exosome-enhanced PRP.

How long do results last? Results vary but most patients maintain their improvements for 12 to 18 months with a single maintenance treatment per year. Lifestyle factors including sun protection, hydration, and nutrition also influence longevity.

Can these treatments be combined with other procedures? Yes. Our doctors can advise on combining these treatments with other medical-grade skin treatments including vitamin IV therapy, medical-grade skincare, and hormone-related skin support where relevant.

Am I a good candidate? Most healthy adults are suitable candidates. Exclusions include active skin infections, certain autoimmune conditions, blood disorders, and pregnancy. Your doctor will assess your suitability at consultation.

What is the difference between PRP and PRF? PRP delivers a high concentration of platelets and growth factors with immediate release. PRF delivers a higher concentration of growth factors in a sustained-release fibrin scaffold, also containing white blood cells and stem cell recruitment signals. PRF is considered the more advanced, natural option.

Why choose a medical setting over a beauty clinic? These are medical treatments. Blood is drawn. Needles penetrate the skin. Complications, though rare, are best managed by trained clinicians. At The PRP Clinic by The Wellness, all treatments are performed or supervised by doctors, ensuring your safety, the quality of your preparation, and the accuracy of your treatment.
