Fat transfer uses a natural “ingredient,” i.e. your own body’s fat cells. There is no need for fillers, injections, or any other foreign substance to enter your body; therefore, you are not subject to any complications or infection that might be brought on by such substances, even if that is a rare occurrence. Moreover, there is no need for repeat treatments as often as every 6-9 months with a cosmetic treatment. Fat transfer is a one-time procedure with a lasting, natural outcome.
