Our Technology

DESIRIAL® is the world’s first range of non-animal, biogradable, injectable hydrogels, exclusively developed to preserve women’s intimate health1. DESIRIAL® products are designed and manufactured in France by Laboratoires Vivacy, the Aesthetic and Anti-Ageing Medicine specialist.

DESIRIAL® products are based on the VIVACY’s exclusive and patented IPN-Like Technology, with stabilised hyaluronic acid and the antioxidant mannitol.

Hyaluronic acid :  Hydrating action

Hyaluronic acid is a naturally-occurring molecule in the human body, particularly in the skin and mucous membranes. It has the specific feature of retaining up to 1,000 times its weight in water2, contributing to the hydration and the tone of the concerned tissues3.

Hyaluronic acid has a short half-life and is soluble in water, so it needs to be cross-linked in order to stabilise the product. This process will bind molecules together according to the patented IPN-Like Technology and will allow to obtain a cohesive gel that will last for several months.

As a result, DESIRIAL® is able to maintain its hydrating capabilities for several months.

The patented IPN-LIKE Technology

The IPN-Like Technology of Laboratoires Vivacy is a unique and patented (since 2007) technology that acquired recognised efficacy and tolerance in the Aesthetic and Anti-ageing Medicine with the STYLAGE® range of dermal fillers.

This technology involves interpenetration of two hyaluronic acid monophasic cross-linked networks to stabilise hyaluronic acid for safe and long-lasting therapeutic effects.

Antioxydant mannitol : Protective Action

Mannitol is an antioxidant incorporated in DESIRIAL® products to limit the gel’s degradation immediately after injection. It scavenges the free radicals generated by the penetration of the needle or cannula during injection. As a consequence Mannitol helps to protect the hyaluronic acid molecules during the first hours after injection4.
