Your body naturally produces hyaluronic acid (HA). It is a water-retaining molecule that has become a common skincare ingredient in moisturizing products. Its quantity in our body decreases with age. Find out what hyaluronic acid is.


Hyaluronic acid is a sticky substance present throughout the body: in the eyes, joints, but especially in the skin. It retains water molecules in the skin, thereby keeping the skin hydrated by creating a barrier that prevents moisture loss. Hyaluronic acid gives the skin a radiant complexion and a more supple appearance.

In addition to being present in moisturizing products, hyaluronic acid is also often found in anti-aging products, because the older a person is, the lower their hyaluronic acid content.


Hyaluronic acid was first discovered in 1934 by German researcher Karl Meyer and his student John Palmer. The name "hyaluronic" comes from the Greek terms " hyalos ", meaning transparent, and " uronic ", referring to its chemical nature. For cosmetics in particular, hyaluronic acid is often produced by biotechnological synthesis from the fermentation of bacteria, cockscombs are often a source.

Today, its essential moisturizing properties make it a key ingredient in all moisturizing products. It is present in moisturizing creams, anti-aging creams, particularly to reduce wrinkles (it is also often present in anti-aging products because the older a person is, the lower the hyaluronic acid content) and in make-up removers. to deeply hydrate the skin during the cleansing process. It is also possible to find it in moisturizing shower gels for smooth and plumped skin.


  • Intense hydration: hyaluronic acid hydrates the skin's surface. It has the capacity to hold up to 1000 times its weight in water. Hyaluronic acid products lock in moisture in the skin, making it look plumper and firmer.

  • Protects your skin barrier: Using a skin care product with hyaluronic acid helps ensure that your skin barrier is functioning properly. This skin barrier allows you protection from the outside world. If this barrier is poorly maintained, it leaves your skin easily affected by external aggressions such as pollution and UV rays. This can lead to dry skin , which causes flaking and rough skin.

  • Excellent Healing: It is also a good healing agent, as it repairs damaged skin tissue and reduces the appearance of fine lines and wrinkles. It improves skin elasticity by compensating for the lack of hyaluronic acid in the body.

  • Helps restore volume and structure: Hyaluronic acid is commonly used in aesthetic medicine in injectable form to help restore facial volume and structure. As we age, our skin can lose elasticity, volume and firmness due to the decrease in natural hyaluronic acid and collagen production. When injected, hyaluronic acid can help fill in areas where volume has been lost, such as the cheeks, temples, lips and facial lines.


Hyaluronic acid, naturally present in our body, is essential for maintaining well-hydrated skin. By acting like a sponge that retains water, it helps preserve skin hydration, thus ensuring smooth and plump skin. This ingredient plays a crucial role in preventing the loss of elasticity and diminishing the appearance of wrinkles, providing skin with a youthful and revitalized appearance. Used in many skin care products, hyaluronic acid is also appreciated in aesthetic medicine to restore facial volume. It is a key ingredient for glowing skin.
