Platelet Rich Plasma
Platelet-Rich Plasma (PRP) is an autologous regenerative therapy that involves the collection of the patient’s own blood, centrifugation to concentrate platelets, and re-injection or topical application of the platelet-rich fraction to targeted areas. PRP typically contains 3-5 times the baseline platelet concentration, yielding 1,000,000 – 1,500,000 platelets/μL. This plasma contains high concentrations of growth factors and bioactive proteins that aid in tissue repair and regeneration.
Mechanism of Action
PRP works by delivering a supraphysiologic concentration of platelets directly to the treatment site. The alpha granules within platelets release growth factors that stimulate:
- Collagen synthesis
- Cellular proliferation and differentiation
- Neo-vascularisation
- Stem cell recruitment
- Reduction of inflammation and stimulation of tissue repair
Key Growth Factors in PRP
- Platelet-Derived Growth Factor (PDGF)
- Transforming Growth Factor-beta (TGF-β)
- Vascular Endothelial Growth Factor (VEGF)
- Epidermal Growth Factor (EGF)
- Insulin-Like Growth Factor (IGF)
Applications for Skin Rejuvenation
Indications:
- Fine lines and wrinkles
- Acne scarring
- Loss of skin elasticity
- Uneven skin tone and texture
- Periorbital pigmentation and thinning
Clinical Benefits:
- Enhanced skin tone and elasticity
- Reduction in scarring and pore size
- Natural collagen remodeling
- Safe for all Fitzpatrick skin types
- Minimal downtime
- low risk of adverse events
Treatment Methods:
- Intradermal or subdermal injection
- Topical application post-microneedling
Recommended Protocol:
- Initial series of 3 treatments 4-6 wks apart
- Maintenance Rx every 6-12 months
Hair Restoration
Indications:
- Androgenetic alopecia
- Telogen effluvium
- Hair thinning from stress or aging
- Adjunctive therapy post-hair transplant
Mechanism in Hair Regrowth:
- Prolongs anagen phase of the hair cycle
- Improves follicular vascularity
- Stimulates stem cells in dermal papilla
- Increases hair thickness & density
Ideal Candidates:
- Early-stage hair loss
- Intact hair follicles
Recommended hair PRP protocol:
- Monthly for 3 months and then every 3 months for 1 year (treatment on months 1, 2, 3, 6, 9, 12)
Clinical Advantages
- Uses autologous material
- reducing risk of hypersensitivity
- Minimally invasive with no surgical recovery time
- Easily combined with microneedling and topical agents
- Appropriate for use across all genders and skin types
Contraindications
- Active infection or dermatologic disease in the treatment area
- Platelet or clotting disorders
- Ongoing anticoagulant or immunosuppressive therapy
- Recent use of isotretinoin (within 6 months)
- Pregnancy/ lactation
- Current use of corticosteroids or immunosuppressive therapy
