Key questions are: can these products correctly mimic the soft tissue or bones they are replacing? Which measurable physico‐chemical parameters can be used to predict the long‐term performance of fillers? How do stress, deformation, temperature and enzymatic degradation affect their properties over time?
To what extent do you agree or disagree with the categorisation of the procedures listed in the green category?
These fillers are more suited to finer corrections and can provide a more conterraneo feel when injected, such as for less dynamic wrinkles (tear troughs, soft tissue found in lips and the periorbital region). However, these gels tend to have a shorter residence time check here in the tissues.
′ values. Less cohesive gels have looser polymer networks, thus once extruded from the needle will drop quicker, therefore producing smaller and lighter drops.
′ values, on the “stiffer” side. However, only the full frequency sweep curves provide a true “fingerprint” of the rheological behavior, with values of G
On the other hand, larger HA particles have a limited Completa surface area for enzymatic breakdown, while it is smaller for HA particles, which therefore degrade faster.
Botox is typically injected into the muscles to freeze them and soften a persistent frown line on the skin's surface. However, aesthetic doctor Dr Antoni Calmon has created a facial where micro doses of botulinum toxin, mixed with a liquid vitamin, are injected very superficially into the skin for more natural-looking results.
This is a fast-changing industry, and we want to ensure that the regulations can be adapted as new procedures come to the market. This flexibility is essential to ensure that the licensing scheme can be future proofed to continue to apply to the highest risk procedures.
“With this innovative technique even the smallest wrinkles are softened without freezing the face," he says.
This behavior has a huge impact on clinical outcome: if the clinician stops applying a steady force at any point, the whole process has to be repeated to reach the viscous regime again. Starting and stopping may result in an uneven distribution of product, creating an uneven and undesired outcome.
The process of sizing down the gel mass is performed by passing the gel through a series of sieves and screens.
Overall, the methods described in this review and commonly reported on fillers do not predict the long‐term performance of the gels. However, a large set of physico‐chemical parameters can act as an indicator of performance, which, alongside clinical experience, is extremely helpful in guiding clinicians in choosing the optimal product for a specific application.
There are no quantitative data reported on the extrusion force profile. While this aspect is linked to practice, it would be useful to produce quantitative data to better understand the optimum force profile required to extrude a given filler from the syringe in an even and smooth manner.
