Where is fat harvested from for facial fat grafting?
⚠️ Watch for signs of infection at the donor site
If you notice increasing redness, warmth, swelling, pus, or fever after your procedure, contact your surgeon promptly. These could be signs of infection that need prompt treatment.
Short answer
Fat for facial grafting is most commonly taken from the lower abdomen and inner thighs, though other areas of the body with sufficient fat can also be used. The choice of donor site is guided by the amount of fat available, patient body type, and surgeon preference.
What the research shows
Several studies point to the lower abdomen and inner thigh as the preferred donor sites for facial fat grafting, particularly in younger patients [2]. A review of procedures performed over nearly a decade confirmed that the abdomen was the most commonly used donor site overall [4] [5]. Other areas of the body with adequate fat deposits can also be used depending on each patient's build and the volume of fat needed [8].
Fat is typically removed using a gentle suction technique (syringe liposuction) with low pressure to protect the fat cells and keep them as healthy as possible before transfer [2] [8]. A numbing solution called tumescent fluid is injected into the donor area first to make the process more comfortable and reduce bruising [7] [8].
Does the donor site matter for results?
Research suggests that the specific donor site does not significantly affect how well the fat survives after transfer to the face [6]. What matters more are patient-related factors such as age, body weight, and overall health, as well as the technique used to harvest, process, and inject the fat [6] [2]. One large study also found that the choice of harvest location did not significantly change the rate of complications at the donor site [5].
What to expect at the donor site
The donor area typically heals well. The overall complication rate at the harvest site is low, around 5.5% in one large study [5]. The most common issues are minor: contour irregularities, temporary firmness, or redness at the site [5]. Patients with a lower body weight may have a slightly higher chance of these minor complications [5]. Bruising and swelling are also common but temporary [7] [8].
What to ask your surgeon
Before your procedure, ask your surgeon which donor site they recommend for you and why. Good questions to discuss include: How much fat will be needed? Will there be a visible change at the harvest site? Are there any areas of your body that are better suited given your body type? Understanding the plan ahead of time helps set realistic expectations for both the face and the donor area.
