Firstly, what is PRP? PRP stands for Platelet-Rich Plasma. Our blood contains platelets, which are a type of blood cell that are responsible for the natural healing process in the body. Their main role is to perform damage-control where they race to the site of injury (cuts in the blood vessels) and form a clot to seal the damage and prevent excessive blood loss. In addition to this, they begin to secrete large quantities of proteins (growth factors) to initiate the tissue healing process to repair the damage.
