Three parameters.
One balance.
The rheological design of Rheolyse is oriented towards the behaviour of the gel in tissue. Rheology describes the response of hyaluronic acid once injected, in relation to the mechanical stresses of the face.
Each parameter is calibrated to work in balance with the others, because the naturalness of the result arises from the coherence between gel, tissue architecture and movement.
G' expresses the elastic component of the gel — its ability to resist deformation and maintain its shape over time. A high G' provides greater structural support; a modulated G' allows the gel to support tissue without stiffening it. Clinically, G' determines how much the product supports and how closely it follows the anatomy.
G'' describes the viscous component of the gel — its ability to flow and adapt under stress. An adequate G'' promotes diffusion within the tissue, improves the continuity of the result and reduces the risk of localised accumulation.
Tan δ represents the balance between viscosity and elasticity. Lower values indicate more elastic behaviour; higher values, a greater viscous component. In Rheolyse gels, tan δ is designed to avoid extreme behaviour, favouring harmonious interaction with the tissue and a natural response to facial dynamics.
How the gel holds
and how it is shaped.
Beyond the rheological moduli, two characteristics define the clinical behaviour of the injected gel: its ability to remain cohesive over time and its ability to adapt to the practitioner's action during treatment.
A cohesive gel does not fragment or migrate; it integrates stably within the tissue planes. Clinically, cohesivity is essential for keeping the product in place and supporting an orderly, controllable result over time.
A plastic gel is easily shaped: it adapts to the patient's anatomical morphology and retains the shape achieved. This parameter allows a progressive, physiological correction, without rigidity.
High G': return.
High G'': adaptation.
The Rheolyse rheological framework considers the ratio between the two components of the gel. When G' prevails, the gel favours structural return and support; when G'' prevails, the gel favours dynamic adaptation and tissue diffusion.
The gel maintains its shape over time, supports the tissue and works as an element of volumetric architecture.
The two components are balanced. The gel supports and at the same time follows facial dynamics, without extreme behaviour.
The gel flows, adapts and distributes itself. It works as an element of physiological integration and progressive stimulation.
Two lines.
One method.
Rheolyse is organised into two complementary lines, designed to address different clinical needs yet united by the same design principle: choosing the behaviour of the product before its volume, to preserve balance, harmony and naturalness.
Cross-linked hyaluronic acid.
Four formulations (Hydrafine, Sublimelip, Dynamic, Deeplift) designed for harmonious integration across the different anatomical planes, with a rheological profile oriented towards naturalness and dynamic control.
Designed to accompany movement and expressiveness, these products promote tissue continuity and proportion, maintaining coherence between structure and function.
Pure, non-cross-linked hyaluronic acid.
Two formulations (Restore 32, Puresense 64) based on pure hyaluronic acid, developed to provide structural response and precision in treatments requiring greater support.
High purity and a defined mechanical behaviour allow accurate control of the result in the anatomical planes with the highest functional demand, respecting the morphology of the face.

Measured cross-linking.
Calibrated naturalness.
The cross-linking process, carried out at low temperature with long reaction times, allows precise control over the structure of the gel. This approach enables measured cross-linking, a reduction in residual chemical agent and the preservation of functional rheological properties.
The Invisible Linked line is formulated with cross-linked hyaluronic acid, calibrated for the different anatomical planes. The Invisible Pure line uses pure, linear, non-cross-linked hyaluronic acid, obtained by bacterial fermentation, for a physiological approach to treatment.
Pure hyaluronic acid
works with the rhythms of the tissue.
The products of the Invisible Pure line form part of a structured clinical pathway in which time is an essential therapeutic factor. Clinical effectiveness requires respecting the intervals between sessions, continuity of treatment and consistent scheduling of the protocol.
Each session contributes to building a progressive, stable response. Unplanned variation of the intervals reduces the quality of the biological response.
