When we get injured, bleeding stops after a while, the wound is closed, and eventually, it becomes a scab and heals. “Platelets” contained in the blood play a role in this series of processes. And focusing on the function of platelets, PRP (Platelet-Rich Plasma) therapy has been adopted in the fields of cosmetic surgery and sports medicine as well as an infertility treatment for several years. It is a regenerative medicine that promotes the healing of various parts by treating the repairability of growth factors contained in platelets in one’s own blood and enhancing the “healing power” inherent in humans.
