Clinically Proven Efficacy!

The expression "Clinically Proven Efficacy" means that a cosmetic has undergone clinical tests to evaluate its effectiveness. Here are the results achieved by our Hyaluronic Acid.

*The clinical tests conducted on a sample of 20 subjects showed significant improvements in the monitored parameters, particularly:
A 25% increase in skin hydration after 15 minutes and a 5% increase after 24 hours of application
A 3% increase in skin elasticity and a 2% increase in firmness after 24 hours of application.

Four Molecular Weights

Our Hyaluronic Acid is composed of different molecular weights that work in synergy with each other:

High molecular weight: The large size prevents it from passing through the skin, but it allows the hyaluronic acid molecule to act on the surface, providing a hydrating and film-forming action that prevents the naturally occurring water on the skin from evaporating.

Medium molecular weight: Medium molecular weight hyaluronic acid is more easily absorbed, even though it cannot reach the deepest layers. It does allow water to pass through, helping to maintain optimal hydration.

Low and very low molecular weight: The small size of the hyaluronic acid molecules allows them to reach the deeper layers and plump and nourish the natural matrix already present.

Properties of Hyaluronic Acid

Hyaluronic acid is a molecule naturally present in our skin, responsible for maintaining hydration and the elasticity of connective tissue.

Thanks to its extraordinary ability to retain water, hyaluronic acid can preserve the skin’s volume and softness, helping to reduce the appearance of wrinkles and improve the overall look of the skin.

Over time, the levels of hyaluronic acid in our body tend to decrease, leading to visible signs of aging, such as wrinkles, dryness, and loss of volume.
For these reasons, hyaluronic acid is an essential component of anti-aging products!
