platelet cells. The blood sample taken is concentrated by placing it in the centrifuge device. As a result of this process performed in a laboratory environment, platelet cells increase 2 to 4 times compared to the first blood sample. After this stage, the concentrated blood plasma is applied to the area to be rejuvenated. The face, neck and décolleté are the most preferred areas. It can also be applied to the hands to rejuvenate the hands and remove age spots. Since the person’s own blood is used in the PRP treatment, there are no unexpected reactions after the application. However, irritation and edema may occur due to incorrect injection. For this reason, PRP treatment must be performed by someone experienced in this field.
