TACKLE ON FOLDS AND FACIAL DEPRESSIONS
1. All about elasticity
What is elasticity? Why is it so important to treat folds and to model the face contours and volumes?
Elasticity is the capability of a strained body to recover its initial shape and appearance when stress is released. The “elastic” module of a substance represents its “solid” component. The gel must have a high elastic module to retain its volume after having been injected into the dermis. A gel that is not elastic enough will never permit the face’s volumes to be modelled as it will not recover its initial capacity.A product’s elasticity must nevertheless be adapted in order to not create too much dilation of the dermal tissues and not to inject solid particles that would hurt the aesthetic effect when touching, even looking at, the injected area.


2. A perfectly adapted elasticity
The capacity of Fortélis Extra to generate a remarkable volume-enhancing effect is the result of the properties of its Extra Volumizing Elasticity: EVE.Thanks to a specially defined cross-linking ratio, Fortélis Extra benefits from exactly the right elasticity level required to work on volumes and correct folds and depressions, while working on the level of the deep dermis.
But what is the correlation between volume augmentation and elasticity?
Theoretical correlation of volume of augmented tissue with elasticity
The graphic, here above, brings out the following elements
- A reduced elasticity cannot efficiently correct folds and depressions.
Gels with a low elasticity level can on the other hand present other qualities linked to their physical and rheological properties. So certain products are able to offer a perfect aesthetic result in the framework of wrinkle treatment due to their capacity for incomparable dermal integration, which is the strength of Esthélis. - A too high level of elasticity necessarily implies the formation of solid particles in an injectable implant.
The biphasic nature of the product consequently increases the risks
of secondary effects linked to the presence of these solid beads. - A perfectly adapted elasticity*, like that presented by Fortélis Extra, makes it possible to obtain a significant increase in volumes while benefiting from all the major recognized virtues of a fluid implant of a monophasic nature.
*perfectly adapted elasticity = high elasticity + a guarantee of maintaining the fluid nature of the product
you expect and demand from a great volume-enhancing implant.

By going to the axis of "Elasticity" at the level of Fortelis Extra's EVE, and by crossing the vertical marker of Fortélis Extra with the different arrows at 3, 6, 9 and 12 months, we observe, by referring to the axis of "Remaining volume of implant in the fold" that the theoretical results of Fortélis Extra’s long lastingness are more than satisfactory.
On the other hand, if we go to this same axis of "Elasticity" at a lower level of elasticity (closer to 0) and we cross this new vertical marker with the different arrows at 3, 6, 9 and 12 months, we notice, still referring to the axis of "Remaining volume of implant in the fold" that the theoretical results of long lastingness are clearly less satisfactory.
Because the elastic module of an implant influences the durability of given volume, Fortélis Extra with ist extra volumizing elasticity offers „real-lasting“ results.
3. The EVE power
Apart from its remarkable volume-enhancing power what does its EVE (Extra Volumizing Elasticity) contribute to Fortélis Extra? The elasticity of an implant influences the longevity of the product injected. This consequently has an effect on the long lastingness of the results correcting the volumes of the sites treated.Theoretical volume degradation over time correlating with the implant's elasticity
This graph clearly brings out the effect of an implant’s elasticity on the long lastingness of the volume acquired over the months following the injection.
