The syringes are kept upside down in the rack for 10 min to remove all the excess blood and plasma oil, and then you are ready to inject (Fig. 23.6). The fat is not centrifuged or washed as there is no evidence that it prolongs its longevity. The author does not expose the fat to the open air and does not use additives to the fat like growth factors insulin or insulin growth factor igf-1 or any nutrients such as polyethylene glycol, or hyperbaric oxygen that has been used in some practices.
