Platelet-rich plasma therapy has moved well beyond its origins in orthopaedic and wound care medicine. Today it sits at the intersection of regenerative science and aesthetic practice, attracting interest from patients and clinicians alike for its use in skin rejuvenation. Understanding what PRP actually is, how it works at a cellular level, and what the research currently supports helps patients approach treatment with realistic and well-informed expectations.
What Is PRP and How Does It Work?
Platelet-rich plasma is derived from your own blood. A small sample is drawn and placed in a centrifuge, which spins it at high speed to separate its components. The resulting plasma fraction is concentrated in platelets, the small cell fragments best known for their role in clotting but also central to the body’s tissue repair processes.
Platelets contain structures called alpha granules, which store a range of growth factors. These include platelet-derived growth factor, transforming growth factor, vascular endothelial growth factor, and epidermal growth factor, among others. When PRP is introduced into tissue, these growth factors are released and interact with local cells, stimulating processes involved in tissue repair, collagen synthesis, and angiogenesis, the formation of new blood vessels.
In the context of skin rejuvenation, it is this capacity to support the skin’s own regenerative activity that underpins the clinical interest in PRP. The treatment does not introduce foreign substances. It works with the biology already present in your own blood.
What Skin Concerns Does PRP Address?
PRP has been investigated in the peer-reviewed literature for a range of skin-related applications. The evidence base is still developing, and outcomes vary between individuals. Current research has explored its use in the context of skin texture and tone, fine lines, acne scarring, and hair loss associated with androgenetic alopecia.
It is important to understand that PRP is not a standalone corrective treatment for all skin concerns, and results depend on a range of individual factors including skin condition, age, lifestyle, and treatment protocol. At Southern Aesthetic’s medispa, PRP is recommended where it is clinically appropriate to your presentation, and your treating practitioner will discuss the current evidence and realistic expectations with you before any treatment proceeds.
How Does PRP Complement Other Treatments?
One of the more clinically useful aspects of PRP is how it integrates with other skin treatments. It is commonly used in combination with microneedling, a procedure that creates controlled micro-injuries in the skin to stimulate collagen production. When PRP is applied during or after microneedling, the growth factors can be delivered more effectively into the dermis through the microchannels created by the needling process.
PRP is also used alongside laser treatments and, in some protocols, with injectable treatments. The rationale is that the regenerative signals from PRP may support skin recovery and augment the overall outcome of a combined treatment plan. Your practitioner will advise whether a combined approach is appropriate based on your skin assessment and treatment goals.
What Does a Typical PRP Treatment Course Look Like?
At Southern Aesthetic, PRP treatments begin with a thorough skin consultation and assessment. This ensures the treatment is appropriate for your individual concerns and that any contraindications are identified before proceeding.
On the day of treatment, a small amount of blood is drawn, typically from the arm. This is processed in a medical-grade centrifuge to produce the PRP fraction. Depending on the protocol recommended for your presentation, the PRP is then either applied topically in conjunction with microneedling or injected directly into the treatment area.
The procedure involves some discomfort, which varies depending on the method of application and the area being treated. Topical anaesthetic is applied beforehand to manage this. Redness and mild swelling following treatment are normal responses and generally resolve within a day or two, though this varies between individuals.
A single session is unlikely to reflect the full extent of any benefit. Most treatment protocols involve a series of sessions, typically spaced several weeks apart, followed by maintenance treatments. Your practitioner will recommend a course appropriate to your skin concerns and monitor your progress throughout.
Is There Any Downtime?
PRP has a relatively low downtime profile compared to more ablative procedures. Most patients return to their usual activities within a day or two. Sun protection is important in the days following treatment, and your practitioner will provide specific post-treatment care instructions.

FAQs
Is PRP safe? Because PRP is derived from your own blood, the risk of allergic reaction or rejection is minimal. As with any procedure involving injections or skin penetration, there are risks including bruising, swelling, infection, and temporary skin sensitivity. Your practitioner will discuss the full risk profile with you during your consultation.
How many sessions will I need? This depends on the skin concern being addressed and your individual response to treatment. A common starting protocol involves several sessions spaced a few weeks apart. Your practitioner at Southern Aesthetic will recommend a course based on your assessment and review your progress as treatment proceeds.
How long before I see results? Because PRP works by supporting the skin’s own regenerative processes, results develop gradually rather than immediately. Many patients notice changes in skin texture and quality over the weeks following a course of treatment. Individual responses vary and your practitioner will give you a realistic picture of what to expect based on your specific presentation.
Can anyone have PRP treatment? PRP is not suitable for everyone. Contraindications include certain blood disorders, active skin infections, some medications including blood thinners, and other medical conditions. A thorough consultation and medical history review is conducted before any treatment is recommended.
Does PRP work for hair loss? PRP has been studied as a treatment for androgenetic alopecia, the most common form of hair loss in both men and women, with a number of studies showing encouraging findings. It is considered a treatment option in appropriate candidates and is assessed individually. Your practitioner will advise whether it is suitable for your presentation.
Can PRP be combined with injectables like anti-wrinkle treatments? In some cases, yes. Combined treatment plans are assessed individually based on your skin concerns and treatment history. Your practitioner will advise on sequencing and suitability during your consultation.
Glossary of Terms
Alpha granules: Structures within platelets that store and release growth factors when platelets are activated. They are central to PRP’s mechanism of action in tissue repair.
Androgenetic alopecia: The most common form of hair loss, caused by a combination of genetic and hormonal factors. Also referred to as male or female pattern hair loss.
Angiogenesis: The formation of new blood vessels. Growth factors released by PRP can stimulate this process, which supports tissue repair and renewal.
Centrifuge: A medical device that spins blood samples at high speed to separate components by density. Used to produce the concentrated platelet fraction in PRP preparation.
Collagen: A structural protein that provides strength and elasticity to the skin. Its production naturally declines with age. PRP is associated with stimulating collagen synthesis through growth factor activity.
Dermis: The deeper layer of the skin, beneath the epidermis. It contains collagen, elastin, blood vessels, and other structures. Many of PRP’s regenerative effects occur at this level.
Growth factors: Proteins that regulate cellular processes including growth, repair, and differentiation. PRP contains several growth factors relevant to skin and tissue regeneration.
Microneedling: A procedure that uses fine needles to create controlled micro-injuries in the skin, stimulating the body’s healing response and collagen production. Often used in combination with PRP.
Platelet-rich plasma (PRP): A concentration of platelets derived from a patient’s own blood, used therapeutically for its growth factor content and role in tissue repair.
Platelets: Small, disc-shaped cell fragments in the blood with a primary role in clotting. They also contain growth factors that support tissue healing and regeneration.
Regenerative medicine: A field of medicine focused on harnessing the body’s own biological processes to repair or restore tissue function. PRP is one tool used within this field.
