Glossary Injectable Platelet-Rich Fibrin

regenerative treatment using concentrated platelets and fibrin from blood

Injectable Platelet-Rich Fibrin (i-PRF) is a regenerative treatment derived from a patient's own blood, which is processed to concentrate platelets and fibrin. This injectable substance is rich in growth factors and cytokines, promoting tissue healing and regeneration, and is commonly used in medical and aesthetic procedures, including hair restoration and wound healing.
