PRP Therapy for Perineal Incision or Tear Scars

Platelet-Rich Plasma (PRP) is a processed fraction of a patient’s own peripheral blood, with a platelet concentration higher than baseline. It is obtained by collecting a small blood sample just before the procedure and centrifuging it to separate the platelet-rich plasma.

PRP therapies have been used for more than 30 years in various medical fields, bringing proven benefits in regenerative medicine. PRP contains living biomaterials such as platelets, leukocytes, fibrin, cytokines, and bioactive proteins. Once applied to tissue, platelets become activated and release growth factors and cytokines that stimulate the formation of new blood vessels, support healing, and promote regeneration.

Activation by the body’s own collagen and thrombin causes platelets to release both pro- and anti-inflammatory mediators, which help reduce inflammation and relieve pain. By releasing growth factors, adhesion molecules, and chemokines, PRP promotes cell differentiation, proliferation, and regeneration.

Growth factors actively secreted by platelets include platelet-derived growth factor (PDGF), transforming growth factor (TGF α/β), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), fibroblast growth factors (FGF), connective tissue growth factor (CTGF), and insulin-like growth factor-1 (IGF-1). Additionally, platelets and leukocytes release anti-inflammatory cytokines, interleukins, and interferons that further support tissue repair.

Through these mechanisms, PRP stimulates healing, tissue regeneration, pain reduction, and immune modulation, making it a safe and effective therapy widely used in modern medicine.
