Not only is the fat relatively easy to harvest via liposuction, but the transferred fat is biocompatible, non-allergenic, non-toxic and relatively easy to obtain in meaningful volumes.
More recently surgeons have used the therapeutic and rejuvenating benefits of fat grafting in the healing of wounds and scars, as well as fat's ability to repair damage to breast tissue following radiation treatment.
The rejuvenative effects are due to the high concentration of mesenchymal cells present in the fat tissue.
This natural 'autologous' resource is therefore readily accepted in the treatment area, is easily topped up and can provide additional rejuvenating benefits.
