I had Microneedling done with PRP and also PRP injections . The system my doctor using is Magellan . However , the PRP was red . The injections were so very painful it felt like a bee sting as PRP was going in. The nurse said that was because of the red blood cells . I thought PRP should be yellow and red blood cells should be removed . Should injections burn? I had a lot of bruising and swelling . Too soon to determine results .
