Biostimulators
Biostimulators at 8th Sense use injectable materials like PLLA, CaHA and PCL to trigger the body’s own collagen production, giving gradual, natural-looking improvements in skin firmness and structure.
Biostimulators are injectable treatments that stimulate the body’s own tissue response, particularly collagen production, to improve skin quality, firmness and structural support.
They are an important part of regenerative aesthetics, where the objective is not simply to correct an aesthetic concern, but to influence the biological processes contributing to tissue ageing.
How Do Biostimulators Work?
With ageing, collagen production and dermal support progressively decline. Biostimulatory materials create a controlled tissue response that can stimulate fibroblast activity and new collagen formation.
Depending on the material, they may also provide an element of immediate structural support.
The main biostimulatory materials used in aesthetic medicine include:
- Poly-L-lactic acid (PLLA)
- Calcium hydroxylapatite (CaHA)
- Polycaprolactone (PCL)
These materials are not interchangeable. They differ in mechanism, tissue interaction, longevity, indications and treatment technique.
What Can Biostimulators Improve?
When appropriately selected, biostimulators may improve:
- Collagen density and dermal quality
- Skin firmness and elasticity
- Mild to moderate tissue laxity
- Facial structural support
- Fine lines and wrinkles
- Age-related changes in facial contours
- Overall skin quality and appearance
Results are generally progressive, because collagen formation and tissue remodelling take time.
Who Is a Good Candidate?
Biostimulators may be appropriate for patients with age-related changes in collagen, skin quality, elasticity and tissue support, who want to stimulate their own regenerative processes and achieve a gradual, natural-looking improvement in tissue quality, firmness and facial structure while maintaining their individual features and proportions.
When Are Biostimulators Contraindicated?
Biostimulators are medical treatments and are not suitable for every patient.
Treatment may be contraindicated, postponed or require specialist consideration in the presence of:
- Pregnancy or breastfeeding, where safety has not been established
- Active infection or significant inflammation at the treatment site
- Known hypersensitivity to the treatment components
- A history of keloid or hypertrophic scarring with materials where this is a contraindication
- Certain connective-tissue or autoimmune conditions, particularly when active or associated with immunosuppressive treatment
- Significant bleeding disorders or other relevant uncontrolled medical conditions
- Unrealistic expectations or a desire for a dramatic change that the treatment is not designed to provide
Importantly, contraindications and precautions are material-specific. They cannot be applied identically to every biostimulator.
FAQ
A biostimulator is an injectable material designed to stimulate a biological response in the tissue, particularly new collagen formation. Common collagen biostimulatory materials include poly-L-lactic acid, calcium hydroxylapatite and polycaprolactone.
Results are usually progressive rather than immediate. Some materials can provide initial structural effects, but the collagen-stimulating effect develops over weeks to months as tissue remodelling occurs.
Longevity varies considerably between materials and patients. Published studies report effects lasting approximately 12–25 months for commonly studied CaHA and PLLA treatments, although results depend on the material, treatment protocol and individual biology.
Not automatically. Some products have limited safety data in patients with connective-tissue disease, active inflammatory conditions or immunosuppressive treatment. The specific condition, its activity, medication and the material being considered all need to be assessed before treatment.
Treatment may not be appropriate during pregnancy or breastfeeding, active infection or inflammation, certain autoimmune or connective-tissue conditions, relevant bleeding disorders, known hypersensitivity, or a tendency to abnormal scarring, depending on the specific material.
Patients with unrealistic expectations may also not be suitable candidates. A medical consultation is therefore essential before treatment.
