Platelet rich plasma (PRP) is an extract of your own blood that contains many times more platelets, growth factors, and active proteins for tissue and injury healing. It has been used medically for years to accelerate wound healing; repair tendon, ligament and joint damage; heal diabetic ulcers; and help regrow muscle and bone. When PRP is placed back into the skin by injection or micro-needling, it initiates a localized stem cell response. Over the weeks and months following treatment, this stem cell response recruits collagen-producing cells called fibroblasts. The fibroblasts replace tissue that has been damaged or lost through the aging process with healthy skin that looks refreshed and rejuvenated.
