In recent years, demand for aesthetic medicine has evolved toward more physiological approaches: restoring skin quality without excessive volumetric modification.
Not all faces are suited for filler treatment. In many indications, the main issue is degradation of dermal tissue (collagen loss, altered elasticity, skin thinning), rather than isolated volume deficiency.
In this context, biostimulation emerges as a central therapeutic strategy.
At Elixyka clinic, we offer JULÄINE®️ (Nordberg Medical), an injectable device based on poly-L-lactic acid (PLLA), specifically designed to induce progressive and controlled neocollagenesis.
Mechanism of Action
PLLA is a biocompatible and biodegradable polymer used in medicine for decades. Injected into the deep dermis or subdermal plane, it acts as an indirect biological stimulus.
Its action relies on:
- A controlled low-intensity inflammatory reaction
- Activation of fibroblasts
- Progressive synthesis of type I and III collagen
Restructuring of the extracellular matrix
This process results in increased dermal density, improved firmness, and restored skin quality. Unlike fillers, JULÄINE®️ does not induce immediate volumetric correction, but progressive tissue regeneration.
Microsphere Technology
The specificity of JULÄINE®️ lies in its formulation of calibrated and homogeneous PLLA microspheres. This architecture enables:
- Uniform tissue distribution
- More regular fibroblast stimulation
- Reduced aggregation phenomena
Better clinical reproducibility
In practice, this translates to more predictable response kinetics and an improved tolerance profile.
Comparison with Other Collagen Inducers (such as Sculptra®️)
Although based on the same active principle (PLLA), galenic differences influence clinical response:
- Particle distribution
- Homogeneity after reconstitution
Tissue diffusion kinetics
The use of calibrated microspheres allows for more homogeneous stimulation, with reduced risk of nodules and irregularities.
Main Indications
Mild to moderate skin laxity
Altered dermal quality (fine, atonic skin)
Moderate wrinkles and folds
Prevention of skin aging
Optimization of results after treatments (laser, peelings, injections)
Treatment Modalities
Deep plane injections (deep dermis / subdermal)
Techniques: cannula or needle depending on zones
Standard protocol: 1 to 3 sessions, spaced 4 to 6 weeks apart
Personalized adaptation according to indication and skin phenotype
Results
Initial improvement: 4 to 6 weeks
Optimal effect: 2 to 3 months
Continuous progression over several months
Duration: up to 18–24 months
Results are progressive, natural, and non-volumizing, with overall improvement in skin quality.
Tolerance and Side Effects
Generally transient side effects:
Erythema
Edema
Ecchymoses (bruising)
Sensitivity at injection site
Adherence to dilution, injection, and massage protocols is essential to minimize the risk of nodules.
Patient Selection
JULÄINE®️ is preferably indicated for patients:
- Presenting with diffuse skin aging
- Wishing to avoid excessive volumization
- Seeking a progressive and biological approach
In preventive or moderately corrective strategy
Therapeutic Positioning
Biostimulation is now established as a complementary pillar to classic techniques:
As an alternative (or in combination) to fillers in certain indications
In association within combined protocols
Prior to more invasive techniques
The shift from a correction logic to a tissue regeneration logic.
Conclusion
JULÄINE®️ represents an evolution in rejuvenation strategies toward more physiological approaches, focused on tissue quality rather than mere morphological correction.
