Hyaluronic acid - high molecular weight

Sodium Hyaluronate

A transparent substance with an exceptional ability to bind moisture, it works like a sponge, absorbing up to a thousand times its own weight in water. It is found in every tissue in the body, particularly in areas that depend on moisture, such as the vitreous humour of the eye, connective tissue and synovial fluid in the joints. It is naturally present in the diet, so nutrition helps stimulate its production in the body. Its concentration in the skin decreases significantly with age, leading to reduced water retention in the skin's connective tissue and resulting in less elastic skin that is prone to wrinkles. It is used to reduce wrinkles, fine lines, sagging skin, scars and post-acne pigmentation. It creates space within tissues for the transport of substances essential for natural cell regeneration, enhancing the skin's ability to regenerate. It is used in the treatment of burns and skin ulcers to restore hydration. It protects against external factors, maintains firmness and elasticity, smooths deeper wrinkles, neutralises free radicals, prevents stretch marks, corrects skin imperfections, speeds up wound healing and minimises scarring. It improves the supply of nutrients from deeper structures to the surface layers. It is obtained from microorganisms through biotechnological processes, ensuring high purity and compatibility with natural cosmetics. The grade used is of the highest global quality, sourced from a leading manufacturer with Ecocert and COSMOS certifications for natural and organic cosmetics.

Its main mechanism of action is intensive moisturisation: it binds and retains water on the skin's surface, restoring the lipid barrier and supporting its protective functions. Its high molecular weight prevents deep penetration, so it remains in the upper layers as a hydrating film that protects against transepidermal water loss. It also has mild antioxidant properties, neutralising free radicals and helping to soothe irritated skin. The recommended concentration in creams is the maximum specified by the manufacturer, typically 0,1-1 % for surface hydration.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it intensively replenishes moisture and reduces wrinkles. It is suitable for all skin types, including oily and acne-prone skin, as it does not clog pores and regulates hydration without leaving a greasy film. It is ideal for people with skin damaged by environmental factors or following intensive treatments.

A study published in the Journal of Clinical and Aesthetic Dermatology (2014) showed that topical application of a 0,1 % solution increases skin hydration by 96 % after a single use and maintains the effect for up to 6 hours. Further research in the International Journal of Biological Macromolecules (2018) confirmed that the high-molecular-weight form improves skin elasticity by 20 % after 4 weeks of daily use at a concentration of 0,5 %.
