What is Hyaluronic Acid?
Hyaluronic acid, also known as HA, is a macromolecule (a very large molecule generated from a repeated motif) naturally produced by our body.
In the joints and cartilage, it increases the viscosity of synovial fluid, the serous liquid that lubricates them. It acts as a shock absorber.
Its presence in the vitreous humor, the gelatinous substance that makes up the majority of our eyes, helps maintain the spherical shape of the eyeball. In fact, it gets its name from this very source: it was first discovered and isolated in 1934 from the vitreous of a cow's eye.
But it is in the dermis that the largest proportion is found: 50% of the hyaluronic acid molecules we produce are located in the dermis and epidermis.
What is their role? They fill the intercellular spaces and provide support for collagen and elastin fibers. Depending on where they are located, they help limit the proliferation of unwanted substances and regulate the migration of cells.
Viscous and elastic, hyaluronic acid contributes to the flexibility of tissues. And because it can absorb up to 1000 times its weight in water, it is essential for maintaining hydration and tissue cohesion.
Hyaluronic acid is particularly abundant during tissue regeneration phases. It plays a central role in the adhesion, growth, and migration of cells in the case of skin inflammation. It promotes epithelialization, a form of healing where epithelial cells (specialized cells that line the surface of the epidermis) divide and gradually cover the wound, allowing it to close.
Our body constantly produces and breaks down hyaluronic acid molecules. However, as we age, we produce less of it naturally. Our hyaluronic acid production decreases by 6% every 10 years. By the age of 50, the amount of hyaluronic acid naturally present in our body is halved. Therefore, external sources of HA are undeniably beneficial!
The 1001 Uses of Hyaluronic Acid
It is thanks to its incredible water retention abilities that hyaluronic acid has become such a celebrity. Its volumizing properties are especially exploited in aesthetic medicine. When injected, it helps fill in wrinkles and fine lines, and compensate for skin laxity. It is also used to enhance the volume of the lips and cheekbones.
Hyaluronic acid is also used to treat osteo-articular conditions like knee osteoarthritis. Its viscosity restores flexibility and mobility to damaged joints.
Some dentists use it to promote healing by spraying it on their patients' gums.
In cosmetics, hyaluronic acid is recognized for its powerful hydrating capabilities. Not only that, but it also helps with intercellular impermeability and the regeneration of the stratum corneum. It triggers the formation of type 1 collagen (responsible for the skin's extensible qualities) and works with elastin to ensure firmness, resistance, and plasticity of tissues.
Its viscosity is also particularly appreciated: by forming a film on the skin's surface, hyaluronic acid limits water evaporation and forms a protective barrier against external aggressions like free radicals and UV rays. It also has soothing and calming properties, which are especially beneficial for damaged skin.
And that's not all: hyaluronic acid is recognized as a safe active ingredient, very well tolerated by all skin types, even the most sensitive!
When Hyaluronic Acid Helps Athletes
Athletes' skin is put to the test. Friction, irritation, shocks, sun exposure, repeated strain, heat, lesions, injuries... Nothing is spared! It deserves tailored care, both to preserve and repair it.
When practicing sports, the properties of hyaluronic acid are particularly beneficial.
"RGTA®" (Regenerating Agent) is an active ingredient derived from three decades of scientific research. Its mission? To restore the microenvironment of cells where it has been degraded by physical effort, thus encouraging optimal tissue regeneration. When combined with exogenous hyaluronic acid (which does not come from our body), it creates a synergistic effect, which has been patented. This combination greatly increases the effectiveness of HA. It maintains its natural production, whereas this is inhibited when hyaluronic acid is used alone. Oxidative stress, which damages cells, decreases. But most importantly, type 1 collagen production is massively increased, improving healing and efficient cell renewal.
Hyaluronic acid can be used as part of a daily routine. Regular application of RGENtec's "After Sport Ritual" on the face and body optimizes the skin's innate repair abilities and maintains its sporting resilience.
When massaged locally with the "Shock and Roll" serum, hyaluronic acid works deeply where the skin has been altered and soothes discomfort. Its formula quickly penetrates the areas of discomfort, particularly around the joints.
"Bye Bye Burn" takes the best of HA and RGTA® to restore, repair, and intensely hydrate skin damaged by sports activity. The result? Optimal recovery and sustained performance.
