Fillers: are fats more beneficial than hyaluronic acid?

In filling procedures, the use of fat taken from the patient himself has been highlighted, with advantages compared to hyaluronic acid

For a long time, hyaluronic acid has been considered the gold standard injectable filler, after all, it has excellent compatibility with the body and good durability. But recently, another substance has gained importance in filling procedures: fat.

“Fat is used more and more often to improve the harmony of the face, rejuvenate and add volume to areas such as the lips and under the eyes, for example. This fat is extracted from the patient himself and, after being treated, is injected again in the desired location”, underlines dermatologist Renato Soriani, member of the Brazilian Society of Dermatology (SBD), expert in dermatological technologies and former coordinator of the Department of Laser and Technologies from SBD (2017-2021).

“And if previously liposuction with hospitalization in a surgical center was the only way to obtain fat for surgery, today there are systems like Lipocube that allow fat to be aspirated with fewer interventions in the office itself under the effect of anesthesia local,” says the doctor.

But, after all, what are the differences between fatty and injectable hyaluronic acid fillers? According to the dermatologist, the main difference lies in the way these two substances are obtained.

“Despite being a substance present in the body and therefore biocompatible, hyaluronic acid is produced in the laboratory. On the other hand, the fat is obtained by the patient himself. It therefore does not cause rejection or allergic reactions, unlike hyaluronic acid, which presents this risk, although low”, highlights Renato.

For this reason, fat is also less inflammatory than hyaluronic acid, and some studies even indicate that the material has anti-inflammatory properties. “Hyaluronic acid can cause inflammation, with localized swelling, especially in the area around the eyes. It is therefore a region where fats are widely used,” explains the doctor.

However, fat is a biologically active material, i.e. it has a high concentration of growth factors and stem cells, especially if treated with Lipocube, which is able to obtain a material with a much greater quantity of these components compared to other processing methods. of fats.

“This way, in addition to filling, the fat also has a regenerating and biostimulating effect, which significantly improves the result,” he says.

And, according to the doctor, the duration of the results is also different: while the effects of filling with hyaluronic acid are visible for about 9-12 months, the fat is only partially absorbed and maintains satisfactory results for up to 24 months.

Another issue is that fat, with a single extraction, can be used for different purposes, including global facial rejuvenation, with the treatment of all factors involved in the facial aging process, from bone resorption and fat compartments to the point of losing skin quality.

“This is because Lipocube is able to break it down into different sizes depending on need: milli, the largest size of fat molecules and ideal for counteracting bone resorption and adding volume; micro, intermediate size used to fill furrows like a Chinese mustache; and nano, the smallest fat particles which, applied superficially by injection or microneedling, give firmness, reduce wrinkles and improve the quality, brightness and structure of the skin”, underlines the doctor.

It is worth noting, however, that the use of fats for fillers does not necessarily replace hyaluronic acid-based fillers. For example, the cost, the area treated and the amount of fat in the patient, even if Lipocube does not require the extraction of a significant amount of material, are aspects to take into consideration. “It is up to the doctor to carry out an assessment and decide, together with the patient, the best procedure for each case”, concludes Renato Soriani.
