The PRP from your blood contains red blood cells, white blood cells, and platelets that contribute to essential growth functions and healing. To prep the PRP, a sample of your blood is run through a centrifuge to concentrate the platelets. The microneedling device creates hundreds of tiny holes in the skin through which the PRP is absorbed. You’ll likely need multiple sessions for optimal results, though you’ll see increased radiance immediately. Over time, the PRP stimulates collagen production, increases cell turnover, and spurs the growth of new blood vessels, resulting in even longer-term effects.
