First, the target area will be cleansed, and then a topical anaesthetic will be applied. About 30 minutes will be spent on microneedling, depending on the area to be treated. A microneedling procedure involves creating a series of tiny, superficial punctures with sterile needles. Your dentist will use a microneedling tool to prick the skin during this procedure, creating tiny punctures on the surface.
Then, a small amount of blood (about ten ccs of blood) will be drawn, usually from your arm, just like when blood is drawn for a normal blood test. The blood will then be placed in a centrifuge, separating the plasma (liquid portion) and the platelets (a type of blood cell that has a vital role in healing) from the other blood components. Occasionally, a second spin is performed to increase the platelet concentration in the plasma. Plasma and platelets contain proteins that help the blood to clot and support cell growth. The platelet-rich portion will then be massaged or injected into the treatment area. During the microneedling procedure, small controlled micropunctures are made in the skin, which allow the PRP to penetrate.
Growth factors and cytokines are present in the PRP. They help skin tissues repair themselves. Both PRP and microneedling promote collagen growth, and they work best when combined.
