What is hyaluronic acid? What are its benefits for the skin and hair?

Some active ingredients transcend trends without ever aging, and Hyaluronic Acid is one of them! Moisturizing and anti-aging, it has established itself as one of the most precious ingredients in modern cosmetics. Naturally present in your body, it takes care of your skin but also your hair. Discover how it works and how to enjoy its benefits even when its production decreases over time.

Hyaluronic Acid is not a laboratory invention. It is a molecule that your body produces naturally, an essential ally.

Hyaluronic Acid is a glycosaminoglycan, a complex sugar chain, abundantly present in the skin, joints, eyes, and connective tissues. Its role? To retain water, ensure tissue suppleness, and maintain their structure.

From birth, our skin is generously provided with it. It is this natural reserve that gives young skin its plump appearance, freshness, and radiance. Over time, Hyaluronic Acid production slows down. Stress and external aggressions weaken it: it dehydrates, loses its firmness and glow, and wrinkles deepen.

Hyaluronic Acid comes in different forms. In its high molecular weight version, it is a macromolecule that, due to its size, remains on the skin's surface. By settling on the outermost layer of the epidermis, high molecular weight Hyaluronic Acid forms an invisible veil that reinforces the skin barrier. It prevents dehydration, leaving the skin immediately smoother, more comfortable, and visibly plumped.

Smaller, low molecular weight Hyaluronic Acid plays a completely different role. It hydrates by stimulating the synthesis of natural Hyaluronic Acid. In other words, it encourages the skin to rehydrate itself. It strengthens the cells' water reservoir and contributes to skin elasticity.

Could Hyaluronic Acid be the key to beautiful skin? Moisturizing, plumping, and anti-aging, it has many benefits.

Hydrating action is THE signature of Hyaluronic Acid. It is its most immediate but also its most well-documented promise. Capable of holding up to 1,000 times its weight in water, it helps all skin types. You also prevent the appearance of dehydration lines that can deepen and then become wrinkles.

Hydrated skin regains its comfort, but the action of Hyaluronic Acid goes even further. Thanks to its exceptional water retention capacity, your skin regains volume and elasticity, and your complexion brightens. Your skin bounces back better under your fingers, and micro-reliefs fade. Plumped and luminous, it looks younger.

Hyaluronic Acid visibly improves the appearance of the skin. Well-hydrated skin resists external aggressions better and regenerates more effectively.

In our Prodigieuse® [HYALU] Boost collection, we combine low molecular weight Hyaluronic Acid with high molecular weight Polyglutamic Acid. This expert multi-molecular duo offers double hydration. Low molecular weight Hyaluronic Acid penetrates the layers of the epidermis to hydrate and improve skin elasticity. Capable of holding up to 5,000 times its weight in water, high molecular weight Polyglutamic Acid forms a protective film, strengthens the skin barrier, and limits dehydration.

The action of Hyaluronic Acid is not limited to the skin. Your hair can also benefit from its benefits.

Your hair is thirsty too! Integrated into hair care, Hyaluronic Acid meets this need with the same precision it does for the skin. It locks water onto the surface of the hair fiber and plumps the hair. Your hair is stronger and less brittle.

Well-hydrated hair is soft and shiny, resisting breakage caused by brushing, heat from styling tools, and friction from your pillow. Hyaluronic Acid smoothes the cuticle - those small scales that cover the hair fiber - for a more even surface that reflects light better. The result? Natural shine, restored suppleness, and visibly denser hair.

The scalp is skin like any other: it deserves the same attention as your face. Often neglected in beauty routines, it is nonetheless the starting point for a healthy scalp. A dehydrated scalp is a weakened area, prone to itching, irritation, and fragile, brittle hair. Hyaluronic Acid brings its moisturizing expertise here. It supports the scalp's skin barrier and balances hydration levels.

The NUXE laboratory uses Hyaluronic Acid in several treatments.

A collection of supercharged skincare products featuring an expert multi-molecular hydrating duo. High molecular weight Polyglutamic Acid and low molecular weight Hyaluronic Acid are combined to hydrate your skin, smooth it, and plump it.

Hyaluronic Acid is at the heart of Super Serum [10] anti-aging skincare. The Super Serum [10] such as the Super Serum [10] Eye contain Natural Hyaluronic Acid obtained by plant biotechnology. It penetrates quickly to hydrate the skin.

With Alfalfa extract and Hemerocallis fulva extract, Hyaluronic Acid is one of the ingredients at the heart of Alfa [3R] Technology. More effective than retinol on 3 levels of action in the skin (in vitro test), Alfa [3R] Technology is integrated into the face care products of the collection Nuxuriance Ultra Alfa [3R] to [R]evitalize, [R]egenerate, [R]esurface the skin.
