Facial Fat Grafting in Londrina: rejuvenation with stem cells
If there is a procedure that I consider truly revolutionary in facial plastic surgery, it is fat grafting. After more than twenty years performing this procedure and following its scientific evolution, I can say: the fat from one's own body is the best biostimulator that exists. No industrial product can deliver what nature has already prepared.
Facial fat grafting is not just about filling wrinkles or restoring lost volume. It is transplanting a living tissue to the face, rich in adipose stem cells, that will integrate permanently and promote real skin regeneration. When I perform this procedure, I am not simply shaping contours; I am transplanting youth.
Why is fat superior to industrial fillers?
Hyaluronic acid, calcium hydroxyapatite, poly-L-lactic acid: all have their place in aesthetic medicine. I use some of them in specific situations. But when the goal is complete and lasting facial rejuvenation, fat offers advantages that no product can match.
First, it is permanent. The fat that survives the first ninety days after transplantation remains forever. Second, it is completely biocompatible; after all, I am transferring tissue from the patient to the patient. Third, and perhaps most importantly: fat carries adipose stem cells that promote true regeneration of the tissues where they are implanted.
The science behind adipose stem cells
Stem cells derived from adipose tissue, known by the acronym ADSCs (Adipose-Derived Stem Cells), are the protagonists of hundreds of scientific studies in the last two decades. What science has proven is fascinating: these cells have the ability to differentiate into other cell types, secrete growth factors that stimulate collagen production, and promote the formation of new blood vessels.
In practice, this means that when I graft fat into a patient's face, I am not just filling. I am implanting a regeneration factory that will work silently for months, improving the quality of the skin, its texture, and its luminosity. Patients often report that their skin looks younger in a way that goes beyond the added volume.

Understanding facial aging: why we lose volume
To understand why fat grafting is so effective in rejuvenation, I need to explain how the face ages. Many
patients come to the consultation believing that the problem is just wrinkles and sagging. The reality is more complex.
Facial aging occurs in three dimensions. On the surface, the skin loses collagen, elastin, and hyaluronic acid, becoming
thinner and less elastic. In depth, the bones of the face undergo resorption, especially in the cheekbone, orbital, and
maxilla regions. And in the middle, the facial fat compartments, which provide support and volume to the youthful face, progressively atrophy.
The result is a face that seems to collapse upon itself. The cheekbones lose projection. The nasolabial folds deepen.
The dark circles become more pronounced. The jawline loses definition. The cheeks, once full and positioned high, seem to slide
down forming the so-called jowls.
Fat grafting reverses this process
When I perform a well-planned facial fat grafting, I am directly addressing the cause of the problem. I restore the
atrophied fat compartments, reposition the lost volume, and, through stem cells, stimulate the regeneration of the skin itself.
That is why fat grafting is so often associated with facelift surgery. In my deep plane facelift, which I consider the
gold standard for rejuvenation, I often combine the technique of muscle and skin repositioning with fat grafting to
maximize the result. The facelift repositions what has fallen; the fat restores what has atrophied.
Miligraft, microfat, and nanofat: understand the differences
One of the most important evolutions in fat grafting was the understanding that different processing produces materials with
distinct properties. Mastering these techniques allows me to use each one where it is most effective.
Miligraft: structural volumization
Miligraft consists of fat particles two to three millimeters in size, preserving the adipocytes (fat cells) intact
within their extracellular matrix. It is ideal for restoring large volumes, such as in the cheekbones, malar region, temples, or to
project the chin.
The advantage of miligraft is that the adipocytes survive well when transplanted in areas with good vascularization. The disadvantage is
that larger particles cannot be injected into very superficial or delicate areas without creating visible irregularities.
Microfat: precision in delicate areas
Microfat is obtained through additional processing that reduces the particles to 0.5 to 1 millimeter. This more refined fat
allows me to work in areas that require greater precision: lips, tear troughs (dark circles), perioral wrinkles (barcode lines), back of
the hands.
The technique I use to process microfat preserves viable adipocytes while removing excess oil and fluids. The
result is a more homogeneous material that can be injected with finer cannulas, offering greater control.
Nanofat: pure biostimulation
Nanofat represents a paradigm shift. Through mechanical emulsification and filtration, the fat is processed until it forms a
liquid emulsion where practically no viable adipocytes remain. What is left? An extraordinary concentration of adipose stem cells,
vascular progenitor cells, and growth factors.
Nanofat does not fill, does not volumize. Its function is exclusively regenerative. I inject this emulsion into the dermis itself to treat
fine wrinkles, improve skin quality, treat pigmented dark circles, and even acne scars. The results I have observed are
impressive: real improvement in skin texture and luminosity that continues to evolve for months after the procedure.
The CAL technique: enhancing results
The CAL technique (Cell-Assisted Lipotransfer) represents the state of the art in fat grafting. The concept is
simple: enrich the miligraft or microfat with an extra concentration of stem cells isolated from another portion of the collected fat.
Scientific studies show that the CAL technique increases the survival rate of the graft from approximately 45% to about
60%. In practice, this means more consistent and predictable results. I use this technique in selected cases, especially
when I need maximum graft survival.
Indications for facial fat grafting
Over two decades of performing fat grafting, I have identified the situations where this procedure offers the best
results:
Global facial rejuvenation
The classic indication. Patients who have lost facial volume with aging and desire a natural and long-lasting rejuvenation.
I often associate it with deep plane facelift or blepharoplasty for complete results.
Dark circles and tear troughs
One of my favorite indications. Dark circles due to volume loss respond magnificently to microfat or nanofat grafting. The
result is superior to filling with hyaluronic acid because it is permanent and promotes improvement in the quality of the local skin.
Permanent lip volumization
For patients who desire fuller lips without the need for periodic reapplications of fillers. The result is
natural and definitive.
Correction of facial asymmetries
Congenital or acquired asymmetries (post-trauma, post-surgical) can be corrected with precision using fat grafting.
Facial lipoatrophy
Patients with facial fat loss due to significant aging, important weight loss, or use of certain medications find
in fat grafting the definitive solution.
Improvement of skin quality
With nanofat, I can treat fine wrinkles, acne scars, photoaged skin, and even stretch marks. The regenerative action of
stem cells promotes a real improvement in skin texture.
Complement to facelift surgery
In my deep plane facelift protocol, fat grafting is often used to restore volume in areas that the facelift cannot fill: temples, cheekbones, deep folds.
Pre-operative: preparing for the procedure
The consultation: detailed planning
The consultation for fat grafting is one of the most detailed that I perform. I analyze the face at rest and in motion, evaluate the
quality of the skin, identify the atrophied fat compartments, and precisely plan where and how much I will graft.
I use standardized photographs and, in complex cases, computer simulation to align expectations. I openly discuss what fat grafting can and cannot do, and whether other associated procedures would be beneficial.
Evaluation of donor areas
I need to identify where I will collect the fat. The most common areas are the lower abdomen, flanks, and inner thighs.
I evaluate not only the available quantity but also the quality of the adipose tissue. Patients who have undergone multiple
previous liposuctions may have fibrous areas that make collection difficult.
Pre-operative exams
I request a complete cardiological evaluation and the following tests:
Complete blood count;
PAT with INR + APTT;
Fasting blood glucose;
Creatinine and urea;
Total proteins and fractions;
Electrocardiogram;
Surgical risk.
Pre-operative guidelines
Discontinue aspirin, anti-inflammatories, and vitamin E fifteen days prior;
Discontinue anticoagulants as directed by the cardiologist;
Do not smoke for at least fifteen days prior (ideally thirty days);
Avoid alcoholic beverages in the week before;
Fast for eight hours on the day of surgery.
The surgery: how I perform the fat grafting
The procedure is performed under general anesthesia or sedation with local anesthesia, depending on the extent. The duration varies from one to three hours, depending on the volume to be transferred and whether there are associated procedures.
Step 1: fat collection
I start by infiltrating tumescent solution in the donor area. This solution contains anesthetic and adrenaline, which minimize bleeding and facilitate aspiration. The collection is done with blunt-tip cannulas connected to low-pressure syringes, a technique that better preserves cell viability.
The fat collected by conventional high-pressure liposuction suffers a lot of trauma and has lower survival. Therefore, I exclusively use a manual technique with syringes, even though it is more labor-intensive.
Step 2: fat processing
The aspirated fat is a mixture of adipocytes, stem cells, blood, anesthetic, and oil. I need to separate what is useful. I use low-speed centrifugation, which separates the layers without traumatizing the cells.
I discard the upper layer of oil and the lower layer of blood and fluids. The intermediate layer, golden and dense, is the purified fat. Depending on the indication, I process this fat into millifat, microfat, or nanofat.
Step 3: grafting
This is the step that requires the most technique and experience. The fat needs to be deposited in multiple microscopic layers, never in blocks. Each small portion of transplanted fat needs to be in close contact with vascularized tissue to survive.
I use cannulas of different calibers, starting with the deeper layers and progressing to the superficial ones. The movement is one of withdrawal, depositing fine threads of fat along the path. It is a handcrafted job that requires patience and precision.
In the areas where I use nanofat, the technique changes: I inject directly into the dermis with fine needles, creating a mesh of regenerative cells under the skin.
Calculated overcorrection
Part of the transplanted fat will be reabsorbed in the first months, even with perfect technique. Therefore, I always graft a little more than necessary, calculating for this expected absorption. The amount of overcorrection varies according to the area and the characteristics of the patient.
Post-operative: recovery and care
The recovery from facial fat grafting is relatively smooth, especially when compared to other facial procedures like lifting.
First 48 hours
There will be swelling and possibly bruising (purple spots), both on the face and in the donor area. This is normal and expected. I prescribe cold compresses, anti-inflammatories, and rest with the head elevated. Most patients report mild discomfort, not significant pain.
First week
The swelling peaks between the second and third day, then begins to decrease progressively. The bruises, when present, start to lighten. You can resume light activities at home, but avoid physical exertion and sun exposure.
In the donor area, the discomfort is similar to that of liposuction: a bruised feeling, improving with gentle movement and the use of a compression garment.
First weeks
By two weeks, most of the swelling has subsided, and you can resume social activities with makeup. The result is still not final. During this period, neovascularization of the graft is occurring, a process in which the recipient tissues form new blood vessels to nourish the transplanted fat.
First trimester
This is the critical period. The fat that will survive is integrating definitively. The fat that will not survive is being reabsorbed. Avoid trauma in the area, do not massage, and maintain strict sun protection. At three months, what remains is permanent.
Final result
The definitive result appears between six months and a year, when the entire integration process is complete and the residual swelling, imperceptible to the naked eye, has completely disappeared. The regenerative action of the stem cells may continue to promote subtle improvements in skin quality for up to two years.
Results: what to expect from fat grafting
Realistic expectations
Fat grafting offers results that no industrial filler can match: permanent, natural, and with regenerative action. But it is essential to have realistic expectations.
The survival rate of the graft, even with perfect technique, varies between 50% and 70%. This means that part of the initial volume will be lost in the first months. Therefore, I perform calculated overcorrection, and in some cases, a touch-up session may be necessary after six months to a year.
What fat grafting can do
Restore volume lost with aging;
Improve facial contours permanently;
Smooth out grooves and depressions;
Improve skin quality through stem cells;
Provide a natural result that ages well with you;
Eliminate the need for periodic reapplications of fillers.
What fat grafting cannot do
Lift sagging tissues (for that, there is facial lifting);
Eliminate dynamic wrinkles (for that, there is botulinum toxin);
Guarantee 100% survival of the grafted volume;
Stop the natural aging process.
The difference of experience
In over twenty years performing facial plastic surgery and more than eight thousand procedures, I have developed a deep understanding of how the face ages and how to restore it. Fat grafting requires not only impeccable technique but also an artistic vision to understand where to place volume and in what quantity.
Fat grafting combines exceptionally with various facial procedures: blepharoplasty for rejuvenating the eyes, facial filling to complement specific areas, mentoplasty for profile harmonization, and lip lift for rejuvenating the perioral area. Also, learn about the first consultation and the investment involved.
My training with Professor Ivo Pitanguy, the greatest name in Brazilian plastic surgery, taught me that our work goes far beyond technique: it is about restoring the harmony of the face while respecting the individuality of each patient. This principle guides every procedure I perform.
If you are considering facial fat grafting, I invite you for a consultation. Let's analyze your face together, discuss your expectations, and create a personalized plan to achieve the natural and lasting rejuvenation you deserve.
Frequently Asked Questions about Facial Fat Grafting
How long does the result of facial fat grafting last?
In my experience, the fat that survives the first three months after the transplant remains permanently. With the techniques I use — low-pressure manual harvesting and controlled centrifugation — I achieve survival rates between 60% and 70%. The result is permanent, although natural aging continues its normal course.
What is the difference between miligraft, microfat, and nanofat?
I use each of these techniques according to the needs of each patient. Miligraft consists of particles of 2 to 3 millimeters, ideal for restoring large volumes such as in the cheekbones and temples. Microfat consists of smaller particles, 0.5 to 1 millimeter, which I use in delicate areas such as lips and dark circles. Nanofat is a stem cell-rich emulsion that I inject into the dermis itself for bio-stimulation and improvement of skin quality.
Does fat grafting replace hyaluronic acid fillers?
They are complementary procedures, and I usually guide my patients about the differences. Fat grafting offers a permanent result and regenerative action of stem cells but requires a surgical environment. Hyaluronic acid, on the other hand, is temporary, lasting from 12 to 18 months, but can be done in the office with minimal downtime. I recommend grafting when the patient seeks a definitive result.
Do the stem cells from fat grafting really work?
Yes, and I have been following this scientific evolution for over twenty years. Studies show that adipose stem cells promote the formation of new blood vessels, stimulate collagen production, and improve skin quality. I use the CAL (Cell-Assisted Lipotransfer) technique in selected cases, which increases graft survival from approximately 45% to about 60%.
Can I have facial fat grafting if I am very thin?
In the vast majority of cases, yes. I usually reassure my thinner patients by explaining that facial procedures require relatively small volumes of fat. Even people with little body fat have enough reserve in the lower abdomen or flanks for a complete facial graft.
When will I see the final result of the fat graft?
I guide my patients that the definitive result appears between six months and one year. At three months, the fat that has survived is already permanently integrated. What I often observe is that the regenerative action of the stem cells continues to promote subtle improvements in skin quality for up to two years after the procedure.
Is more than one session of fat grafting necessary?
It depends on the case. Since part of the fat is naturally reabsorbed in the first months, some patients may require a touch-up session after six months to a year. In my practice, most patients are satisfied with a single session, but I evaluate individually during the postoperative follow-up.
Can fat grafting be combined with a facelift?
Yes, and this is one of the combinations I perform most often. In my deep plane facelift, I frequently combine fat grafting to restore volume in areas that the facelift cannot fill: temples, cheekbones, and deep folds. The facelift repositions what has sagged; the fat restores what has atrophied. Together, they offer complete rejuvenation.
What is the recovery like after facial fat grafting?
I consider the recovery relatively smooth. In the first few days, there will be swelling and possibly bruising, which are normal. I recommend that my patients rest with their heads elevated and use cold compresses. By two weeks, most of the swelling has subsided, and it is possible to resume social activities with makeup. Return to work usually occurs between seven and fourteen days.
Can nanofat treat acne scars and fine wrinkles?
Yes, and the results I have observed are impressive. Nanofat, being a concentrated emulsion of stem cells without viable adipocytes, can be injected directly into the dermis to treat fine wrinkles, acne scars, and photo-aged skin. The improvement is real and progressive, continuing to evolve for months after the procedure.
