Summary
This guideline provides evidence-based recommendations for preparing platelet-rich fibrin (PRF) and its dermatological applications. It details specific centrifugation protocols for solid and liquid PRF, emphasizing timely blood processing for optimal use in skin rejuvenation and wound healing.
Area of Science:
- Dermatology
- Regenerative Medicine
- Biomaterials
Background:
- Platelet-rich fibrin (PRF) is a derivative of autologous blood increasingly used in dermatology.
- Standardized protocols for PRF preparation and application are lacking, hindering consistent clinical outcomes.
- The Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) established a taskforce to address this gap.
Purpose of the Study:
- To establish evidence-based recommendations for the preparation and clinical application of PRF in dermatology.
- To provide practitioners with a clear framework for utilizing PRF effectively.
- To consolidate expert opinion and literature evidence on PRF protocols.
Main Methods:
- A comprehensive literature search was conducted across multiple databases for studies on PRF.
- Evidence grading and recommendation strength were assessed using the GRADE framework.
- A draft of recommendations was critically evaluated by the IADVL Academy of Dermatology.
Main Results:
- The A-PRF+ protocol (200g for 8 min) is recommended for solid PRF preparation.
- The C-PRF protocol (700g for 8 min) is recommended for liquid PRF preparation.
- Swing-out bucket or horizontal centrifuges are recommended, with centrifugation initiated within 90-120 seconds of blood draw.
Conclusions:
- The recommended PRF preparation protocols aim to optimize its use in dermatological treatments.
- PRF demonstrates potential as monotherapy or adjunct therapy for skin rejuvenation and non-healing ulcers.
- These consensus recommendations provide a standardized approach for PRF implementation in clinical practice.

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

7.4K
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
