A small amount of blood is taken from the patient. The blood plasma obtained by subsequent centrifugation has a very high proportion of platelets and growth factors. The plasma and platelets are now enriched with substances such as amino acids and vitamins and injected into the subcutaneous tissue by a doctor using fine needles. This initiates a natural regeneration process which stimulates the growth of connective tissue cells and collagen production as well as the formation of new vessels.
