WHAT IS NANOFAT?
Nanofat injection is a method to reduce fine lines and wrinkles, or generally to improve skin quality, in the face. Nanofat is delivered like a filler injection except in this case the material used is autologous fat (one’s own fat cells).
Fat grafting (or fat transfers) are not exactly a new procedure. The procedure where grafted fat is used to volumize and lift the face, have been around for a long time. Techniques and methods have improved over time of course. However, the advent of NanoFat represents a quantum leap in Fat Grafting. We are now able to treat even the fine lines under the eyes and around the mouth using Nanofat delivered with a very fine cannula.
The ability to micronize fat cells down to very fine spheres has opened up many new possibilities, and as such the field of fat grafting has re-gained in popularity in the last few years.
WHAT IS NANOFAT USED FOR?
Nanofat can deliver skin quality improvements like the reduction of fine lines and wrinkles. Recent studies have also shown that nanofat can improve the appearance of old scars.
Used together with MilliFat and MicroFat, we can reverse a host of the signs related to aging. The only thing it does not treat is pigmentation. But it can reverse skin damage due to sun (or UV) exposure.
WHAT IS THE FAT GRAFTING PROCEDURE LIKE?
The procedure involves harvesting fat from the abdomen or the inner thighs under local anaesthetic – essentially a mini-liposuction.
The fat is then cleaned, filtered a separated into different size cells, MilliFat, MicroFat or NanoFat. The larger fat cells are used to revolumize and lift the face, using a technique that Dr David Loh published. The technique has been commonly called the DL Lift.
The smallest of the fat cells are the Nanofat. They are used for the reduction of lines and wrinkles. Or for general skin quality improvements.
During the whole process from extraction, filtration to re-injection, the fat cells are completely free from environmental contamination (scientific jargon: closed system).
Post procedure, there will be some bruising and discomfort in the donor area (the area where fat was harvested). This may take a few days to a week to recover. The overall discomfort is generally mild.
The face where the fat has been grafted will also be slighted swollen (about 20% bigger, I would say), and be slightly tender (sore to touch). Some bruising is to be expected, but again the overall recovery process is quite comfortable.
HOW LONG CAN THE GRAFTED FAT LAST?
A certain percentage of the transplanted fat will not take in the new environment and undergo apoptosis. Usually for the face, because of the rich blood supply, graft survival rates are quite high. You can expect somewhere in the region of 40%-60% grafted fat survival rates. So, we only need to over transplant by a little to achieve the desired outcomes.
After about one-month, whatever fat cells that remain will last forever. They will have been incorporated into the face and will last forever barring the ravages of time. In fact, they will expand and contract with extremes of weight fluctuations.
