Platelet Rich Plasma is a kind of treatment that uses the blood of individual patients to create a special serum for their particular medical or cosmetic conditions. Medical practitioners harvest a small quantity of blood from your forearm and spin it at high speeds in a centrifugal device. The spinning motion causes the platelets and other growth components to separate from the red blood cells and white blood cells. Doctors then isolate the resultant PRP serum and insert it into the treatment site. Here the serum sets off a cascade of healing reactions so that your skin repairs. PRP dermatology is the branch of the therapy that specifically deals with dermal problems.
