GA Level 4 Award in Platelet Rich Plasma (PRP) and Platelet Rich Fibrin (PRF) Treatments Using Microneedling - Core Content — Gatehouse Awards Ltd Occupational Qualification Service Industries Revision
This unit covers the fundamental scientific principles and practical skills required for safely performing PRP and PRF treatments with microneedling. Learn
Topic Synopsis
This unit covers the fundamental scientific principles and practical skills required for safely performing PRP and PRF treatments with microneedling. Learners will master blood collection, centrifugation protocols, activation techniques, and the selection of appropriate microneedling parameters to achieve optimal patient outcomes in aesthetic and therapeutic contexts. Mastery of these core skills ensures safe, evidence-based practice and underpins advanced clinical decision-making.
Key Concepts & Core Principles
- Autologous blood preparation: Understanding the centrifugation process to separate PRP (platelet-rich plasma) and PRF (platelet-rich fibrin) from whole blood, including the use of anticoagulants for PRP and no anticoagulants for PRF.
- Growth factors and cytokines: Knowledge of key growth factors (e.g., PDGF, TGF-β, VEGF) released from platelets and their roles in cell proliferation, angiogenesis, and collagen synthesis.
- Microneedling technique: Principles of using a derma roller or pen to create microchannels in the skin, including needle depth (0.5-2.5 mm), speed, and pattern to optimise product delivery and minimise trauma.
- Safety and contraindications: Identifying absolute contraindications (e.g., active infection, blood disorders, pregnancy) and relative contraindications (e.g., anticoagulant therapy, keloid scarring), plus aseptic technique and waste disposal.
- Treatment protocols: Step-by-step procedures for combining PRP/PRF with microneedling, including skin preparation, product application, post-treatment care, and expected outcomes.
Exam Tips & Revision Strategies
- When compiling your treatment portfolio, include clear photographic evidence with standardized lighting and positioning to demonstrate clinical progression.
- For written assignments, reference current evidence-based guidelines on platelet concentration thresholds and correlate them with needle depth selection.
- In practical assessments, verbalize your rationale for device settings and product choice—this demonstrates underpinning knowledge to the examiner.
- Prepare a quick-reference summary of absolute contraindications (e.g., active infection, platelet dysfunction disorders) and relative contraindications to show safer practice.
- Practice calculating centrifugation parameters from given protocols; assessment tasks may test conversion of g-force to rpm based on rotor radius.
Common Misconceptions & Mistakes to Avoid
- Confusing PRP with PRF, leading to incorrect preparation methods such as adding anticoagulants to PRF tubes or activating PRP unnecessarily.
- Applying too much pressure during microneedling causing unnecessary trauma, excessive pain, and poor treatment tolerance, instead of using controlled, gliding passes.
- Failing to maintain an aseptic chain during tube transfer and application, increasing infection risk despite a clean procedure.
- Using a ‘one-size-fits-all’ needle depth across all facial zones, ignoring anatomical variations and risking nerve injury or inadequate stimulation.
- Overlooking post-treatment aftercare advice, such as sun avoidance or skincare restrictions, which can compromise results and lead to complications.
Examiner Marking Points
- Award credit for demonstrating accurate aseptic technique during blood draw and sample handling, including correct use of sterile equipment and disposal of sharps.
- Credit for correctly explaining the differences between PRP and PRF in terms of fibrin matrix, growth factor release kinetics, and appropriate clinical applications.
- Evidence must show appropriate selection and justification of microneedling device settings (depth, speed) based on the treatment area and desired outcome.
- Look for clear documentation of informed consent procedures and comprehensive patient assessment, including contraindications and pre-treatment photography.
- Assess for sound understanding of centrifugation variables (relative centrifugal force, time) and their impact on platelet concentration and product quality.
