Thanks to its properties hydrophilicthe hyaluronic acid (HA) is a key resource for combating skin ageing and keeping skin looking young and healthy.
Did you know that the skin is the largest organ in the body? It comprises almost 15 % of the body's weight. Y more than 50 % of the hyaluronic acid in our bodies is found in the skin.
Hyaluronic acid and collagen help to keep the epidermal layers functioning perfectly and also support them structurally. Collagen gives consistency to the skin and HA is what nourishes and hydrates the collagen.
Imagine our dermis as a network of collagen fibres that move easily within a viscous substance made up of hyaluronic acid. In this way, the collagen fibres remain moist and well hydrated.

These watery conditions allow the skin to adapt to the alterations in shape and volume that occur when bones and ligaments move. It is also what helps when we move, lean on a surface or when we are pinched, to immediately the skin is restored to its previous state and without any marks visible to the naked eye.
Skin remains smooth and elastic when it has high concentrations of hyaluronic acid. It is not only the ageing of the skin that influences HA levels, but also the effects of UV radiation and environmental pollutants that fill the cells with dirt and hinder their ability to produce it.
Summary of the benefits of hyaluronic acid for the skin
- It increases their hydration. When consumed in nutritional supplements, they hydrate all layers of the skin from the inside out. In addition, the joints and internal organs also benefit from its water-retaining properties.
- Increases skin elasticity and turgidity. So the skin does not generate immediate wrinkles on contact, as is the case with very dry or very dry skin. dehydrated.
- Prevents skin ageing. Hyaluronic acid is involved in two vital cell renewal processes: proliferation and division. Ageing is associated with deficient cell renewal, which HA combats and, in cosmetics that include it, greatly boosts these processes once it has been applied to the skin for two to four months.
- Promotes the elimination of free radicals. The latter are pirates who steal our youth. Free radicals proliferate when we abuse exposure to the sun's ultraviolet rays. Not only should we be concerned about ageing, ultraviolet radiation causes mutations in genetic material (DNA and RNA) and can eventually lead to skin cancer. The sunscreen products that include cross-linked hyaluronic acid keep the skin protected and healthy; you should use them daily even in winter.
- Participates in tissue repair. Tissue regeneration is useful both in the cosmetic sector (facial rejuvenation) and in the medical regenerative sector. This property of hyaluronic acid and its high presence in joints has allowed the development of infiltration methods to combat inflammatory and degenerative diseases. It is also injected in cases of cataracts, producing notable improvements, and it also heals mouth ulcers.
Who can take hyaluronic acid nutritional supplements?
HA is highly recommended for both men and women from the age of 30. Use it just when you start to notice the first signs of skin ageing.

Ideally, we should consult a dermatologist about our situation so that he or she can prescribe the most suitable products.
Who should use hyaluronic acid cosmetics?
Women and men from the age of 35 should start using cosmetic products that include hyaluronic acid among their active ingredients.
As we grow older we must change our facial care routines. Without excuses and with a lot of discipline, from the age of 50 onwards, HA is a must in our cosmetic kit. Its daily application will help us to maintain the skin with more volume and tone not only on the face, but all over the body. body.
Uses of hyaluronic acid in aesthetic medicine
Hyaluronic acid is introduced under the skin of the face with injections. These fill in the furrows on the sides of the nose, lines on the chin, wrinkles around the lips and expression marks on the cheekbones. HA injections are more effective in the long term than Botox injections for facial rejuvenation treatments as it is more easily reabsorbed by the skin.
It is also a friendly substance that does not produce allergic or rejection reactions as it is a substance that our body already possesses and recognises. Only in very exceptional cases do some people have an allergic reaction because the hyaluronic acid that is injected comes with additional molecules (cross-linked) and the hyaluronic acid molecules are further cross-linked.
Cross-linked HA has a molecular weight of 2000k Daltons (HA used in cosmetics only has a weight of 30 Daltons). This substance is doubly viscous and resistant to the body's own degradation. Thus, an area where HA is injected remains filled for almost a year, but is eventually absorbed by the body.
Uses of hyaluronic acid in cosmetics
Many creams, serums and gels include hyaluronic acid as one of their active ingredients.
HA in creams easily penetrates into the deeper layers of the skin due to its low molecular weight (compared to injected hyaluronic acid).
Some of the products of SOIVRE with hyaluronic acid that we recommend are:
- Eye contour gel which also contains retinol and collagen to provide intense hydration and visibly reduce under-eye puffiness and wrinkles.
- Flash Lifting Ampoules able to give your skin a perfect appearance thanks to the combination of collagen, vitamin C, hyaluronic acid and aloe vera. They are perfect for erasing signs of fatigue and stress on the face.
- Vitamin C Serum an anti-ageing revitaliser that we have enriched with HA.
- Corrective CC Cream that gives your epidermis a unified and healthy tone, while preventing and attenuating wrinkles thanks to its HA content and other active ingredients.
