The duration of a vampire therapy session varies according to the area treated, but also to the particularities of each patient. In general, a PRP therapy session for the face, neck or décolletage lasts about 40 minutes. The doctor collects the right amount of venous blood, then the blood is centrifuged until the red blood cells separate from the plasma. The platelet-rich plasma is then injected into the face, neck, neckline or hand area, where it will stimulate collagen production and tissue regeneration. Because this treatment method uses your own blood, there is no risk of allergy, and side effects are minimal and disappear within hours.
