PRP-Platelet-rich plasma (PRP) therapy uses injections of a concentration of your own platelets to accelerate the healing. They can be applied to skin,hair, genitalia or injured tendons, ligaments, muscles and joints. PRP injections are prepared by simply collecting your own blood and running it through a centrifuge to concentrate the platelets. These activated platelets are injected directly into the area in need of rejuvenation and healing, signaling to the body to attract growth factors to the area.
