Fat Transfer: Q&A
Ask a QuestionHow Long Does Fat Last After Harvesting?
If I have Liposuction, and some of the fat is stored for use in other areas (ie. cheeks, lips, or under the eyes), will it still be safe or good for injection 3 months after it was stored? I would like to consider having liposuction on my inner thighs, and have some of it placed in my cheeks, then wait another 3-4 months to have it touched up with the original fat from the first procedure.

Longevity of fat harvested for Fat Grafting
Fat Grafting requires specialized training and specialized surgical instruments, as well as patience and attention to detail on the part of the surgeon. Fat that has been collected through tradtional liposuction will not be viable for lasting fat grafts. A relatively new technique, structural fat grafting, in which small amounts (less than 0.1 cc at a time) of fat are carefully microinjected in a series of discrete layers to gradually 'build' new soft tissue structure.

Frozen fat is dead fat
Dear CLN,
Fat that is frozen is essentially dead fat. It can be injected at a later date, but its viability will be short lived. In other words, you may appreciate a volume increase for a short period, but it will quickly dissipate.

Store fat in your body
In my opinion, the best place to store fat is in your body. I would recommend doing the initial procedure, and if you need an additional injection of fat, I would re-harvest fat from you at that time. The survival would be far superior to fat stored in a freezer and it would eliminate the possibility of mixing up your fat with someone else's that may have been stored in a freezer.

Storing fat is not effective.
Hi! Even fresh fat atrophies to some extent. (This is highly variable and depends on technique). Stored fat is not viable and I don't do it.
In fact, I don't know any experienced plastic surgeons in New York who store fat. This seems to be done primarily by dermatologists. And it is safe enough. I just don't think it works.

How does injected fat last?
The question is how viable was it when it was first harvested. The number drops steadily from there over time.
In our published studies, we found 20-25% viability of fat cells immediately after harvest. Other studies have shown a slow decrease in live cells over time.
The effects of fat injection are twofold: temporary volume replacement, and eventual permanent results.
Your temporary results may be the same with old fat or new fat, however the long term results will not be since fewer...

Best to use harvested fat right away
We like to use the fat right away after harvesting, as we depend on the viability of the fat cells for the result. Although widely used, I do not store fat any longer because I prefer optimal fat survival. It is relatively easy to obtain more fat before the next treatment.
Other surgeons may store fat for up to 1 year, recognizing that survival will likely decrease. There are always pros and cons.

Only use fresh fat for fat grafting
Fat grafting is an extremely effective and powerful technique for recontour and the face and body. It works best when liposuction is performed to one area and the fat that is collected is immediately cleaned and process and then immediately transferred to another part of the body. Remember that your ultimate result will largely depend on the technique that was used in the quality of the fat. Fat has been frozen has been criminally damaged with ice crystals. This can make the fat produce...

Fat Transfer and Storage
Fat that is harvested for transfer should be used right away. Stored fat has unpredictable survival and there is always a concern about bacterial contamination or "sterility" of a biological product stored under conditions which have poorly defined industry standards -- especially in a private clinic setting.

Stored fat not long-lasting as fresh fat
The fat that is stored is usually not as long-lasting as fresh fat. Unless you are extremely thin, there is always some fat available in other parts of the body for fresh fat transfer. This is easily done with local anesthesia and is preferrable to frozen fat.

Low risk to store harvested fat
Fat injection itself is a relatively unpredictable process, so I do not think you are losing anything to store the fat if you know you will want to have another session. You have to figure in less than 100% take anyway, although the storing of fat certainly doesn't improve its quality.
However, be sure your surgeon or facility has the ability to store properly. There is a small risk of contamination or mislabeling that can occur if storage procedures are not strict.
