Human blood consists of several components, including platelet rich plasma (PRP) which is full of growth factors that repair damage in the body. In a PRP treatment, a medical professional obtains a blood sample from the patient, the blood is then placed into a centrifuge, which separates the blood and Platelet-rich plasma can then be harvested. PRP can be injected directly into the skin or can be applied topically to the skin when coupled specifically with microneedling.
