Hyaluronic acid (HA) comes in various forms.

Which one is best for your skin?

The etymology of “Hyaluronic” derives from the Greek word “hyalos”, meaning glassy or vitreous. This name was attributed by Karl Meyer who was the first to discover, in 1934, Hyaluronic Acid (HA) in the vitreous humor of a cow’s eye.

What scientists have discovered

Hyaluronic Acid is thought to play important functional roles in healthy skin by controlling the phenotype of epithelial cells. In addition, Hyaluronic Acid content governs general functions of the skin such as water content, turgidity, elasticity, and diffusion of nutrients.

Chronic UVB irradiation induces loss of HA from the dermis thereby, contributing to the quiescent phenotype of dermal fibroblasts.

(Excerpts from an article published in The American Journal of Pathology, Vol. 171, 2007)

This complex scientific description demonstrates that Hyaluronic Acid has remarkable and complex properties that make it essential to safeguarding healthy skin.

What is hyaluronic acid?

Besides its cell management functions, which continue to be the subject to further research, Hyaluronic Acid is particularly known for its capacity to retain a huge quantity of water molecules on its surface: 1 gram of Hyaluronic Acid can retain up to 6 liters of water (Sutherland, 1998)!

Hyaluronic Acid is a chain of sugars widely present in our organism. 50% of it is concentrated in the skin! Depending on where Hyaluronic Acid is located in the skin, its molecular weight (and therefore the length of its chain) varies: the deeper it is, the shorter the chain is.

Hyaluronic Acid can also be of synthetic origin. It is widely used in anti-aging products because its hydration and filling capacities to keep the skin plumped and moisturized.

Unlike the Hyaluronic Acid produced naturally within the skin, with a length that corresponds to a specific function, synthetic Hyaluronic Acid is produced in a predefined length determined by the ingredient’s manufacturer.

Even if produced with care and an optimal length, the body might consider it as “foreign” and destroy it. Moreover, the use of synthetic Hyaluronic Acid, for example in an HA-rich cream, can signal to the skin that it no longer needs to produce its own HA, thus slowing down natural regenerative processes.

For all these reasons, it is self-evident that no man-made synthetic is better than physiological HA which is intrinsic, efficient and produced in the right place at the right time.

Why is the precursor approach best for your skin?

Precursors are essential basic elements to feed and boost the skin regeneration process.

What are the advantages?

Rivoli’s new Hyaluronic Acid ASPRivoli® precursor is exceptional because it features a highly adaptive molecular configuration that is closest to the physiological configuration, for an optimally hydrated, plumped and rejuvenated skin.

The following Rivoli products are formulated with HA ASPRivoli® precursor at concentrations with proven efficacy in clinical testing.

L’Eau de Jour

L’Eau de Nuit

Le Privilège - Base Traitante

Le Visage - Crème Nutrition Intense

suggest that RIVOLI’s bestselling treatments, which are formulated with high HA-precursor concentrations, produce remarkable visible results on skin, and specifically on the visible signs of aging.
