IPN-Like Technology



Laboratoires VIVACY has developed “IPN-Like Technology” (InterPenetrated Networks), a unique cross-linking technology for hyaluronic acid that accurately defines each product’s viscoelastic properties₁.

From a clinical standpoint, the main product characteristics sought after by Physicians are their ability to lift skin tissues, provide mechanical support and spread easily. To obtain these desired effects, the HA gel must have a unique combination of elasticity and viscosity₂ .

These specific viscoelastic properties determine where the gel will be injected, allowing it to respond to the various mechanical stresses to which it will be subjected in the tissues.

As a result, the interpenetration of HA cross-linked networks:

Optimises the products’ rheology, in particular the viscosity to guarantee good product injectability.
Preserves the partial independence of the interpenetrated HA networks, whilst increasing the density of chemical nodes.
Guarantees the cohesion of the HA gel and its monophasic properties.
