The search for aesthetic treatments that promote natural and lasting results has driven the popularity of Collagen Bioestimulators.
Celebrities like Camila Pitanga They have already revealed to be adept at the technique. In an interview with Poddelas, in April this year, the 47 -year -old actress said she never had butt or filling, but laser treatments and biostimulative injections, which enhance the natural production of collagen in the body.
But how do these substances work? We explained below.
What are and how collagen biostimulators are applied
Unlike facial fillers with immediate effect, collagen biostimulators act progressively, encouraging the body itself to produce protein, which is essential for the firmness, elasticity and support of the skin.
For this, there is a controlled inflammatory process. “This stimulus attracts cells to the region, especially fibroblasts, which are responsible for the production of collagen”Explains Alessandra Romiti, advisor to the Cosmiatric Department of the Brazilian Society of Dermatology (SBD).
In addition to this well -known action, recent research points a duplicate: Bioregeneration. In this approach, bioestimulators activate, which help in the restructuring of both collagen and fat beneficial to the support of the face and body.
Substances and Indications
Currently, three types of biostimulators are approved for use in Brazil:
- Poly-L-Lactic acid (PLLA), known commercially as sculptra or eleva;
- Calcium hydroxapatite, such as radiis;
- Policaprolactone, whose best known representative is Ellansé.
Each has distinct composition, presentation and application mode, but all share the objective of reactivating collagen production.
The choice of the ideal substance and the proper dosage should be made by a specialist doctor, considering the person’s individual characteristics and needs. Applications can be performed on the face, neck, lap, abdomen, buttocks, arms and other areas that have sagging.
However, unlike procedures with immediate effect, such as fillers with hyaluronic acid, biostimulators have progressive action. “The peak action of collagen stimulus happens about three months [após a aplicação]”, Alessandra points out.
Both PLLA and Calcium Hydroxapatite can last up to 24 months. Policaprolactone is usually longer lasting, with an action of up to four years (although the substance used in Brazil lasts only two years).
E O PMMA?
It is also considered a collagen biostimulator, but the common cases of complications involving their misuse have made him poorly seen in aesthetic offices.
Used as a filling substance for aesthetic purpose, the compound can cause severe and even death injuries when poorly administered. “He is a definitive filler,” warns the doctor.
In January 2025, requesting the definitive prohibition of polymethylmethacrylate as a filling substance in Brazil. The compound, however, is still allowed in the country.
Who can and who cannot do
Despite the many benefits, treatment with bioestimulators is not suitable for all. Those who have active infections in the area to be treated, pregnant women or patients with permanent fills should avoid the procedure.
“People who already have PMMA in some regions of the face may not be indicated for the use of biostimulators.”
In addition, medical evaluation is essential to ensure the safety and effectiveness of treatment. The homemade application or performed by non -qualified professionals generates health risks.
Natural Results
Collagen biostimulators stand out for promoting a subtle and natural improvement in skin quality without major changes in facial structure. This differentiates them from procedures associated with the so -called “facial harmonization”, a term popularized by.
Combined with healthy lifestyle, such as balanced diet, smoking abandonment and adequate skin care routines, biostimulators can have their effects enhanced. “Smoking can be less than treatment response and need more sessions or more product,” adds Alessandra.
The number of applications and the amount of product used vary according to the treated area, the age and skin state of each patient. Because it does not offer immediate effect, biostimulators require continuous patience and medical follow -up. Maintenance varies according to the patient.
Oral Bioestimulation: Myth or ally?
Oral collagen supplementation still divides opinions in the scientific community. According to the doctor, some professionals understand that consuming collagen their entire life would have no harm; Others understand that it is more important to ingest them when stimulating injectable collagen stimulation.
According to Alessandra, the punctual use of so -called collagen peptides may be useful in the three months after the onset of biostimulation, as the body is actively producing the poter. Supplementation is also valid for people with restrictive diets. “Who does not eat much protein (like the vegetarians and vegans), protein supplementation, such as collagen, can help in this lack of intake. ”
