First, a small amount of blood, typically 10-20 milliliters, is drawn from the guest’s arm. The collected blood is then placed in a centrifuge machine, which spins it at a high speed. This process separates the blood components based on their density. The PRF layer, which contains a high concentration of platelets and growth factors, is carefully extracted, and transferred into syringes, ready for injection. While the blood is spinning, a topical numbing cream is applied to the treatment areas to minimize any discomfort during treatment.
