Hyaluronic Acid
Hyaluronic Acid (HA) is a linear Polysaccharide belonging to the Glycosaminoglycans, formed by repeating units of D-glucuronic Acid and N-acetyl-D-glucosamine. In the human body, the average concentration of Hyaluronic Acid is about 200 mg per kg of weight. It is naturally present in the extracellular matrix of connective tissues and contributes to their hydration, elasticity, and integrity. Hyaluronic Acid has hygroscopic, rheological, and viscoelastic properties, and there are many functions performed by this substance in the human body.
The use of Hyaluronic Acid is widespread both in Food Supplements, to support Skin and Joint Health, and in cosmetic products and medical devices for topical or injectable applications.
It is well known for its extraordinary ability to retain water, and its use is extremely widespread. This characteristic makes it indispensable for keeping the skin hydrated and radiant. When combined with Marine Collagen, Hyaluronic Acid enhances the moisturizing effect, helping to create softer skin that is free of blemishes and wrinkles.
Oral intake of Hyaluronic Acid as a dietary supplement is generally well tolerated. Available clinical studies, even at dosages up to 200 mg/day for prolonged periods (e.g., 12 weeks), have shown no relevant side effects in the healthy population. Possible reactions (rare) include mild gastrointestinal disturbances (bloating, feeling full, mild nausea) and hypersensitivity reactions in predisposed individuals (e.g., individual intolerances to the ingredient or components of the formulation).
Key Features
Hyaluronic Acid is available in various forms depending on its molecular weight, which determines its properties and applications:
Type
High molecular weight
Medium molecular weight
Low molecular weight
Molecular Weight (Da)
> 1.000.000
500.000 – 1.000.000
< 500.000 (fino a 50.000)
Main Features
Filmogenic, protective and surface moisturizing action
Good balance between surface hydration and penetration
Optimal skin penetration, deep action, stimulation of internal synthesis
Cosmetic products containing Hyaluronic Acid (creams, serums, masks) are considered safe. Possible side effects, though rare, may include mild skin irritation or redness in people with particularly sensitive skin, and allergic contact reactions (extremely rare).
Key Benefits
Thanks to its structure, it has an extraordinary ability to bind and retain water (up to 1,000 times its own weight), helping to:
- Maintain hydration and skin tone.
- Promote skin elasticity and firmness.
- Improve skin firmness, elasticity and hydration.
- Lubricate and protect joints.
In the case of medical applications involving Hyaluronic Acid injections (fillers, joint injections), side effects are generally local and temporary: redness, swelling, or pain at the injection site and/or the formation of small subcutaneous nodules (dermal fillers); rare cases of inflammatory reactions or infection (joint injections or non-sterile or contaminated fillers)
Hyaluronic Acid is not recommended in the following cases: known hypersensitivity to the ingredient; a history of severe allergic reactions to HA-based products; or use during pregnancy or while breastfeeding, unless otherwise advised by a healthcare professional. Please remember that it is always important to consult a healthcare professional before starting any new supplement or treatment.
