PRP is derived from your own blood via a blood draw just like when you have lab work completed. A fraction of blood (10ml ) is drawn, which is relatively small amount. The blood is then spun in a special centrifuge to separate its components (red blood cells, platelet rich plasma (PRP) and plasma. These growth factors include platelet derived growth factors interact with the local cells and send signals that initiate a variety of events such as cell division and migration. The basic idea behind PRP topical application and injection is to deliver high concentrations of growth factors to an area of aging and/or scarring. At WHAM we use PRP both topically after Dermapen or laser treatments .
