Numerous studies report dynamic frequency‐sweep tests conducted in oscillatory mode, using parallel‐plates
While addressing these questions should be a long‐term endeavor, the objective of this review is to present the state of research on cross‐linked HA dermal fillers, focusing on current methods and parameters reported in the literature, to evaluate whether these measurements can be used as a valid measure of how HA fillers may perform in vivo.
Instead, a HA gel with low viscosity may be more suitable for superficial indications (such as fine lines and wrinkles) as the product will flow and spread more, giving a profile more akin to the area that is being treated.
Many authors report crosslinking density as the factor with the greatest influence on the rheological properties, specifically the stiffness of the gel.

A strong correlation between swelling factor and cohesion has also been reported: the further away the product is from equilibrium swelling (the point beyond which the product phase separates between a polymer‐rich and a water‐rich phase), the more cohesive the product is.
Botulinum toxin injections (commonly known as Botox) are used in the face to reduce lines and wrinkles, such as crow’s feet and frown lines, by relaxing the underlying muscles.
The resulting mixture is then centrifuged, the supernatant removed, and the resulting hydrated gel weighted. The swelling ratio can be calculated using the following equation:
Red: procedures with the highest risk of complications. In line with the proposal on CQC regulation of cosmetic procedures outlined above, bringing specified high-risk procedures into CQC regulation, so that they fall outside of the scope of the licensing scheme.
This treatment is recognised as a surgical procedure for registration with CQC when applied by registered healthcare professionals, or those under their supervision.

I have sensitive skin and it doesn’t irritate whatsoever, and it completely disappears without any white cast or greasy feeling.”
“I have a huge number of patients who are bothered by their under-eye area, but would not be ideal candidates for tear trough filler given the presence of eye bags or lack of elasticity," he notes. "Now I am able to use polynucleotides, which really improves this area and is a conterraneo alternative.”
