How many percent of fat cells will stays alive during a fat transport to the face?

Fat grafting is an excellent form of filler that is considered permanent in most. As your question alludes to, only a percentage of the fat that is injected will take. This will vary from patient to patient and from surgeon to surgeon. In optimal conditions, approximately 50-70% of fat will survive. Best of Luck!This answer has been

professional for appropriate care.

hello , as a general rule about 50-60% of fat graft should be retained if done properly.this may vary depending on the site and previous surgery.technique and placement are very important.good luck.

Fat grafting is not predictable yet.  A good study showed the amount of fat which survives ranges from 30-70%.  There was another study done in diabetic mice which showed 0% survival.  We usually estimate about 50% survives.  There are some factors which affect fat survival which you have control over: smoking, no compression on the new fat, your general health.  There are some factors which seem to be inherent in a person. I have many blogs on my website on this.We know fat grafting works.  It is not completely predictable yet, so some people get better results than others.  See a surgeon who specializes in fat transfer. 

A plastic surgeon cannot predict exactly how much fat will survive. It varys from patient to patient and area to area. Fat requires some kind of scaffolding in order to survive, so more hollow areas will likely require more fat, and may have less survival rate than areas with more fulness. If a physician is new to fat grafting, and especially if they are not confident about their instrumentation and technique, then they may tend to over-graft thinking that a large amount of the fat probably will not survive. However if a large amount of that grafted fat does survive, the patient is left with an unnatural and sometimes bizarre look. Another part of the problem can be the physician's aesthetic vision and understanding of facial aging. There are facial areas where adding volume restores a more youthful appearance, but others where adding volume creates a distinctly unnatural appearance. Balance and overall facial harmony is important as well - for example, overfilling the jawline and lower face will create a heavy, square-jawed, masculine appearance. Look for many before and after photos to find a plastic surgeon who is very experienced and who shares your aesthetic sensibilities. 

Depends on the location of the fat transfer.  Fat that is properly harvested, handled, and transferred below the eyes and in the cheeks has the highest survival of about 70%.  Areas such as the lower face and particularly the lips have the lowest rates of survival.
