Fat is harvested via liposuction from areas that have excess fat such as the abdomen or inner thighs. The liposuction canula is inserted in a very small incision site that does not require stitches for healing. The fat is then "resized" to smaller, softer particles using a type of "straining system". The Microfat and/or Nanofat (Nanofat is molecularly smaller than Microfat) is then injected into areas of the face needing volume or structure using a small needle or canula. The fat acquires a blood supply and will stick around for a long time, and in some cases even permanently. The abundance of fat relative to filler and the longevity of the results often makes this a more cost-effective treatment for patients with significantg volume loss.
When fat is injected in the temples, chin, cheeks, nasolabial folds, marionette lines, and lips, the results not only improve the thickness of the skin but also the dermis and the epidermis. It is suggested by scientists that this improvement is caused by stem cells transferred with the fat infiltrating the skin and causing a rejuvenating effect.
