This publication presents a new skin model assay to evaluate the projection capacity of HA fillers. This skin
model assay was proven to be reliable and reproducible with two HA volumizers, including the market
leader Juvéderm Voluma. It allows easy highlight of the ability of a HA filler to project the tissue and to
create volume. It also enables a comparison of the projection capacity levels of different volumizing HA
products. This model is therefore considered as a new key tool, complementary to the rheological property
of projection force F , to assess the projection capacity of the HA fillers.
N
The additional acquired knowledge obtained with this new skin model assay contributes to a better
characterization of the HA fillers which could be selected and used by the physicians for optimizing their
aesthetic outcomes, as well as patient safety and satisfaction.
