Is 20cc a reasonable amount for entire face fat transfer?

It all depends on what you're trying to achieve. Fat can be injected into the cheeks, brows, temples, nasolabial folds, chins, lips, really anywhere that needs volume!  For a full face rejuvenation, I think it's a good amount, because it's important to remember that 25-30% of it gets resorbed by the body, so you do have to "over inject" today in order to achieve the desired result several weeks from now. This is why you need an experienced injector, one who can asses you and properly predict what you're going to need. Fat is superior to commercially produced fillers because not only does it provide volume, it also brings with it stem cells, and all the benefits they provide, fresher skin, healthier tissue, etc. With regards to repeat treatments, there is no set time frame. Everyone ages differently. It could be a year, it could be 5 years before you need your next treatment.  The key is maintaining good follow up appointments with your doctor. I wish you the best!

Thank you for your questions. With fat grafting, there is no standard by which to measure. It depends on the deficiencies you had and the areas you were trying to treat and how much. As well as the fact that some of the fat will absorb so cautious over-correction is usually appropriate. Depending on how many ares were treated (everyone has a different definition of "full face"), I do not think 20 cc is an unreasonable number....I have done more and I have done less. As for repeating a treatment, I would wait at least 12-18 months before repeating facial fat grafting. Good luck!

if the fat is properly spun down and concentrated at the appropriate centrifuge speed, I feel that 20 mL injected into the face should be sufficient.
