Scar Revision combines two processes, microneedling and platelet rich plasma application (PRP).
Microneedling involves the use of a device that contains fine needles which puncture the skin at various depths to create a controlled skin injury. Each puncture creates a channel that stimulates new blood supply and new collagen synthesis to fill these microscopic wounds.
PRP application involves extracting a few milliliters of blood from the patient and then spinning it in a centrifuge to separate the plasma, the fluid part, from the red and white blood cells. The fluid part is then injected into the scar, during this process the platelets release various regenerative growth factors. Growth factors send messages to the body’s cells and tell them to start the healing process. By concentrating the platelets and placing them directly into a scar we can encourage the body to heal itself.
