Platelet Rich Plasma is your own blood, which is spun to remove the white and red blood cells. When injected into the body it will become the tissue into which you inject. For example, women may have filler (hyaluronic acid) which is natural injected into the face to create fullness. The body will eat the filler and it will need to be repeated in four to six months. With PRP, the body is stimulated with its own stem cells to create more collagen and growth factors. After six to eight weeks, the improvement can be evaluated and treatment repeated to build upon the progress from the first therapy. Generally, after three treatments, the patient will only need a touch up once or twice a year to keep the skin rejuvenated. This is much different from continually filling and deflating the skin with filler.
