I perform fat grafting multiple times each week. It can be performed alone or in conjunction with other surgery. I must disagree with the surgeons who suggest that fat grafting needs to be "over-corrected" It is true that some fat may be reabsorbed, but in some cases it does not reabsorb. The over-corrected "look" is a look we can all identify. That is not a look most people want. Look at dozens of before and after photos soon aftera fat grafting procedure and then a year or more after, as evidence of efficacy and to be certain the surgeon you select shares a similar aesthetic ideal. In your case, a natural look. Having said that, I do not over-correct in the lips or anywhere else. I do regularly perform fat grafting to the lips. However, the lips swell more than any other area of the face and therefore, the downtime is more significant. I generally perform fat grafting of the lips in conjunction with fat grafting to other areas of the face while patients are experiencing a downtime / recovery period. When performed by a nurse injector with considerable experience and a light hand, the results of Juvederm to the lips can be very natural looking. Whether you are have a fat grafting surgery (yes, it is surgery, check your surgeon's credentials carefully including hospital privileges) Or Juvederm. the result is due to the provider, not the product. Some nurses are masterful with Juvederm, others simply are not. Look at lots of photos, ask questions, have a consultation first with no treatment, look at the lips of other staff members and take your time finding someone you can trust with your appearance.
