PRP is a concentrated portion of your blood generally injected back into your body at specific sites to promote healing.
Blood is comprised of many things, such as red blood cells, white blood cells, platelets, plasma, and growth factors. When your body, for example your skin, is wounded, the wound sends out signals that there has been a disruption and the healing cascade starts, with the end result of forming new collagen/skin. Growth factors are part of the healing cascade and help to start the healing process.
