What is platelet-rich plasma (PRP)?
Although blood is mainly a liquid (called plasma), it also contains small solid components (red cells, white cells, and platelets.) however platelets also contain hundreds of proteins called growth factors which are very important in the healing of injuries. The platelets are separated from other blood cells and their concentration in increased during a process called centrifugation. Then the increased concentration of platelets is combined with the remaining blood. Causes virtually no scarring although swelling and light bruising may appear in the area for a few days; facial rejuvenation: 4 treatments are required at 4 to 6 week intervals.
