Is it safe to inject corpse fat into my buttocks?

There has been much discussion of the use of injections for augmentation of the buttocks. It is important to separate fact from fiction.
Fact:
Buttock augmentation is performed either through 1) autologous fat transfer and 2) buttock implants. Fat transfer involves the harvest of fat from an area of excess followed by processing (technique varies). The processed fat is then re-injected to the target augmentation area. Implants are solid silicone devices which work in a similar fashion to the more familiar breast implants. Theses devices are placed under skin/muscle to achieve a volumizing effect.
Fiction:
There is no FDA  approved filler approved for injection in the setting of buttock augmentation. Unfortunately, these procedures are typically performed outside of the realm of board certified plastic surgery by unlicensed practitioners. Patients often times are naive to what is actually being injected and the complications can be serious.
There are newer products such as Renuva. Renuva is an fat alternative to liposuction. However, it is designed to address minor aesthetic defects, such as liposuction irregularities, depressed scars and loss of volume in the hands and cheeks. The injected fat is rehydrated resulting in an injectable filler which preserves the extracellular matrix of the allograft fat. This serves as a framework to support the growth of new fat at the injected site. This, however, is a costly alternative to autologous (your own) fat.I am not familiar with the "Zombie BBL." The use of donor fat would not work (outside of an identical genetic twin). Thus "zombie BBL" would seem to be theoretically flawed (not to mention dangerous). processed options like Renuva are in theory (not in practice) an option.
As always, seek consultation with a board certified plastic surgeon.

Dear donnavittoria,
at the moment you can use only your own body fat because transferred fat from another person will cause bad reaction of your own body and a number of issues. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.
