PRP Therapy
Platelet-rich plasma injections for skin rejuvenation and hair restoration
Platelet-rich plasma (PRP) therapy is a regenerative treatment that uses a concentrated preparation of the patient's own blood platelets to stimulate healing, collagen production, and tissue regeneration [1]. The procedure involves drawing a small amount of the patient's blood, processing it in a centrifuge to isolate the platelet-rich fraction, and then injecting or applying this concentrate to the treatment area. PRP contains a high concentration of growth factors and cytokines that accelerate the body's natural repair mechanisms.
In aesthetic medicine, PRP therapy is used for facial skin rejuvenation (often called the "vampire facial" when combined with microneedling), under-eye hollowing and dark circle improvement, hair restoration for androgenetic alopecia, and scar treatment [1]. The autologous nature of PRP -- using the patient's own biological material -- minimizes the risk of allergic reactions or rejection, making it one of the safest injectable treatments available.
PRP therapy has gained significant popularity as both a standalone treatment and as an adjunct to other procedures including microneedling, laser resurfacing, hair transplant surgery, and dermal filler treatments. The growth factors in PRP, including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-beta), and epidermal growth factor (EGF), work synergistically to promote tissue repair, angiogenesis, and collagen synthesis.
Overview
The therapeutic use of platelet-rich plasma originated in oral and maxillofacial surgery and cardiac surgery in the 1980s and 1990s, where it was used to promote wound healing and tissue regeneration. Its application subsequently expanded into orthopedic and sports medicine for tendon, ligament, and joint injuries. The application of PRP in aesthetic medicine and dermatology has expanded rapidly over the past decade, driven by clinical evidence supporting its efficacy for skin rejuvenation and hair restoration.
PRP is typically prepared by drawing 10 to 60 mL of the patient's venous blood into tubes containing an anticoagulant. The blood is then processed in a centrifuge, which separates it into layers based on cellular density. The platelet-poor plasma (top layer), platelet-rich plasma (middle buffy coat layer), and red blood cells (bottom layer) are separated, and the PRP fraction is collected. A quality PRP preparation concentrates platelets to three to five times their baseline level in whole blood, yielding a growth factor-rich concentrate [1].
For facial skin rejuvenation, PRP can be administered through direct injection into the dermis using fine needles, applied topically in conjunction with microneedling, or used as a combination of both techniques. The micro-channels created by microneedling allow PRP to penetrate into the deeper skin layers where its growth factors can directly stimulate fibroblasts and promote collagen and elastin production. Clinical studies have demonstrated improvements in skin texture, tone, elasticity, and fine wrinkles following PRP treatments.
PRP therapy for hair restoration targets the hair follicles in areas of thinning. The growth factors in PRP are believed to stimulate dormant hair follicles, prolong the growth (anagen) phase of the hair cycle, increase blood supply to the follicles, and thicken miniaturized hairs [1]. Multiple clinical studies have shown increased hair density and thickness in patients with androgenetic alopecia following a series of PRP treatments. The treatment is used both as a standalone therapy and as an adjunct to hair transplant surgery to improve graft survival and growth.
The variability in PRP preparation systems, protocols, and concentrations across different providers and studies has made standardization challenging. Factors including the centrifugation speed and duration, the volume of blood drawn, the specific preparation system used, and whether activating agents (such as calcium chloride or thrombin) are added all influence the final platelet concentration and growth factor content. Patients should inquire about the specific PRP system used by their provider and the expected platelet concentration.
Techniques & Approaches
For facial PRP injections, the treatment begins with blood collection, typically 10 to 20 mL drawn from the arm. The blood is processed in a centrifuge for 5 to 15 minutes (specific parameters depend on the preparation system). The isolated PRP is then drawn into syringes for injection.
The face is cleansed and a topical numbing cream is applied for 15 to 20 minutes. Using a fine-gauge needle (30-32 gauge), the provider injects small volumes of PRP (0.05-0.1 mL per injection point) into the dermis in a grid-like pattern across the treatment area. Injection depth targets the papillary and reticular dermis. Common treatment areas include the under-eyes (tear troughs), cheeks, nasolabial folds, perioral lines, and forehead. A serial puncture or linear threading technique may be used depending on the area and treatment goal.
When combining PRP with microneedling (the "vampire facial"), the PRP is applied topically to the skin immediately before and during the microneedling procedure. The microneedling device creates thousands of micro-channels that allow the PRP to penetrate deep into the dermis. After microneedling is complete, additional PRP is applied and gently massaged into the skin. This combination approach may produce superior results compared to either treatment alone.
For hair restoration PRP, the scalp is numbed with local anesthetic (nerve blocks or topical numbing), and PRP is injected directly into the scalp at the level of the hair follicles. Injections are spaced approximately 1 cm apart across the areas of thinning, with particular focus on the hairline, crown, and any areas of most significant miniaturization. Each injection deposits a small bolus of PRP (0.05-0.1 mL) in the subcutaneous tissue near the follicular bulge region. A typical scalp treatment involves 50 to 100 injection points.
Who Is a Good Candidate?
Ideal Candidates
Ideal candidates for PRP skin rejuvenation are adults seeking natural improvement in skin texture, tone, firmness, and fine wrinkles. Those who prefer treatments using their own biological material rather than synthetic injectables are well-suited for PRP. Patients with under-eye hollowing, early aging signs, and dull skin often see the most noticeable improvement.
For hair restoration, ideal candidates are men and women with early to moderate androgenetic alopecia (thinning hair) who still have active hair follicles in the treatment area. PRP is most effective when initiated before significant baldness has developed, as it cannot regenerate completely dormant follicles. Patients seeking to complement medical hair loss treatments or enhance hair transplant results also benefit from PRP.
Not Suitable For
PRP therapy is not suitable for individuals with platelet dysfunction disorders, thrombocytopenia (low platelet count), blood cancers, sepsis, or active infections at the treatment site. Patients taking anticoagulant or antiplatelet medications should discuss the safety of temporarily discontinuing these medications with their prescribing physician.
Those with chronic liver disease, autoimmune conditions affecting platelets, or hemodynamic instability are not appropriate candidates. Pregnant women should avoid PRP treatments. For hair restoration, patients with complete baldness in the treatment area (no remaining active follicles) are unlikely to benefit from PRP alone. Patients who are unable to provide an adequate blood sample for processing are not candidates.
Individuals with unrealistic expectations should understand that PRP produces gradual, moderate improvement rather than dramatic transformation.
Risks & Benefits
Benefits
PRP therapy offers a natural, biocompatible approach to tissue regeneration using the body's own healing mechanisms. The autologous nature of the treatment means there is no risk of allergic reaction or foreign body response, making it one of the safest injectable treatments available.
The treatment is versatile, applicable to facial rejuvenation, hair restoration, scar treatment, and as an adjunct to numerous other cosmetic procedures. PRP can enhance the results of microneedling, laser resurfacing, and hair transplant surgery, making it a valuable complement to a comprehensive treatment plan.
There is minimal downtime associated with PRP treatments, with most patients returning to normal activities immediately. The procedure itself is relatively quick, typically completed in under an hour including blood draw and processing time. The growth factors in PRP stimulate genuine tissue regeneration rather than simply masking aging signs, providing improvements in skin quality and hair health that reflect actual biological enhancement.
Risks & Considerations
PRP therapy has an excellent safety profile because it uses the patient's own blood, eliminating the risk of allergic reactions, immune rejection, or disease transmission [1]. The most common side effects are mild and temporary, including redness, swelling, bruising, and tenderness at injection sites, typically resolving within one to three days.
Pain during injection varies by treatment area, with scalp injections generally being more uncomfortable than facial injections due to the density of nerve endings. Adequate local anesthesia minimizes discomfort. Infection is a rare risk that is mitigated through sterile blood processing and injection technique.
Temporary headache may occur following scalp PRP treatments. Post-inflammatory hyperpigmentation is uncommon but can occur, particularly in patients with darker skin tones if combined with aggressive microneedling. Results may be disappointing for patients with unrealistic expectations or advanced conditions (such as extensive baldness) that are unlikely to respond to PRP alone. There is no risk of systemic side effects from the PRP itself, as it is composed entirely of the patient's own biological material.
Alternative Procedures
For facial skin rejuvenation, dermal fillers provide immediate volume and wrinkle reduction, while PRP works gradually through collagen stimulation. Botox addresses dynamic wrinkles through muscle relaxation rather than tissue regeneration. Microneedling alone (without PRP) stimulates collagen production through mechanical micro-injuries and represents a less expensive alternative, though the addition of PRP may enhance results. Laser treatments and chemical peels offer skin resurfacing effects through different mechanisms.
For hair restoration, minoxidil (Rogaine) and finasteride (Propecia) are FDA-approved pharmaceutical treatments for androgenetic alopecia [1]. Minoxidil is a topical solution that stimulates hair growth, while finasteride is an oral medication that blocks the conversion of testosterone to dihydrotestosterone (DHT). Low-level laser therapy (LLLT) devices are FDA-cleared for promoting hair growth through photobiomodulation. Hair transplant surgery offers the most definitive solution for significant hair loss by relocating healthy follicles from donor areas.
Growth factor serums and exosome therapies represent emerging alternatives that deliver concentrated growth factors without the blood draw component of PRP. However, these products are less well-studied and may face regulatory scrutiny regarding their composition and marketing claims.
Preparation & Recovery
Pre-Surgery Preparation
Stay well-hydrated in the 24 hours before your appointment, as adequate hydration makes blood draw easier and may improve platelet quality. Eat a nutritious meal before the appointment to maintain stable blood sugar during the procedure.
Avoid blood-thinning medications and supplements for three to seven days before treatment, including aspirin, ibuprofen, naproxen, fish oil, vitamin E, and ginkgo biloba, unless medically contraindicated. Consult your prescribing physician before stopping any prescribed medications. Avoid alcohol for 24 hours before the appointment.
For facial treatments, arrive with clean skin free of makeup and skincare products. For scalp treatments, wash your hair the morning of the appointment but avoid applying styling products. Inform your provider of all medications, supplements, medical conditions, and any history of blood disorders or platelet abnormalities.
Post-Surgery Care
After PRP facial injections, avoid washing the face or applying products for at least four to six hours to allow the PRP to absorb into the tissue. Mild redness and swelling are expected and typically resolve within 24 to 48 hours. Avoid active skincare ingredients (retinoids, acids, vitamin C) for 24 to 48 hours after treatment.
For PRP combined with microneedling, follow standard microneedling aftercare: avoid makeup for 12 to 24 hours, use only gentle cleansers and bland moisturizers for two to three days, and apply broad-spectrum sunscreen daily. The PRP provides an excellent healing serum for the micro-channels created during microneedling.
After scalp PRP treatments, avoid washing your hair for at least 12 hours. You may experience mild scalp tenderness and swelling for one to two days. Resume normal hair care routines after 24 hours. Avoid strenuous exercise and excessive heat exposure (saunas, hot tubs) for 24 to 48 hours after any PRP treatment to minimize swelling and support healing.

Expected Results
For facial skin rejuvenation, patients typically notice an initial glow and improved skin texture within one to two weeks after PRP treatment. More significant improvements in skin firmness, fine wrinkles, under-eye hollowing, and overall skin quality develop over two to three months as collagen remodeling progresses [1]. A series of three to four treatments spaced four to six weeks apart produces the best results, with maintenance treatments every six to twelve months.
For hair restoration, results develop more slowly. Patients may notice reduced hair shedding within the first one to two months, followed by gradual increases in hair density and thickness over three to six months. Most clinical studies show measurable improvement in hair count and density after three to four PRP sessions [1]. Full results may take six to twelve months to become apparent. Maintenance sessions every three to six months are typically recommended to sustain hair growth.
Results vary significantly between individuals due to differences in platelet count, growth factor concentrations, the body's healing response, and the specific condition being treated. Age, overall health, nutritional status, and the severity of the baseline condition all influence outcomes. PRP works best for patients with early to moderate hair thinning rather than advanced baldness, and for skin rejuvenation in patients with mild to moderate aging signs.
Frequently Asked Questions
How does PRP therapy work for skin rejuvenation?
PRP therapy works by concentrating the growth factors found in your own blood platelets and delivering them to the treatment area. When injected into the skin or applied after microneedling, these growth factors -- including PDGF, VEGF, TGF-beta, and EGF -- stimulate fibroblasts to produce new collagen and elastin. They also promote the formation of new blood vessels (angiogenesis) and accelerate cellular turnover. Over the following weeks and months, the treated skin develops improved texture, firmness, and elasticity as the newly produced structural proteins mature and integrate into the existing tissue.

Is PRP effective for hair loss?
Clinical studies have demonstrated that PRP therapy can be effective for androgenetic alopecia (pattern hair loss) in both men and women, particularly when thinning is in the early to moderate stages. Research shows measurable increases in hair count, density, and thickness after a series of three to four treatments. PRP growth factors are believed to stimulate dormant follicles, prolong the growth phase of the hair cycle, and improve blood supply to follicles. However, PRP cannot regenerate follicles that have been completely lost. Results vary by individual, and maintenance treatments are typically needed every three to six months.

How is PRP different from the vampire facial?
The term "vampire facial" specifically refers to the combination of PRP with microneedling. PRP therapy alone involves injecting platelet-rich plasma directly into the skin using fine needles. The vampire facial combines microneedling, which creates thousands of tiny channels in the skin, with PRP applied topically so it penetrates through these channels into deeper skin layers. The combination may produce enhanced results compared to either treatment alone, as microneedling provides its own collagen-stimulating effect while the PRP delivers concentrated growth factors directly where they can be most effective.
