Despite the simple nature of its composition, a large number of other biological functions have been discovered. It not only acts as a biological glue that plays a role in lubricating joints and contributing to maintaining the cohesion of certain types of conjunctive tissue, but also works as a micro-environmental signal that co-regulates cell behaviour during the embryonic development of morphogenesis, the healing of wounds, repairing and regenerating
L’acide hyaluronique se trouve dans l’ensemble du corps (50% dans la peau). Il y a 15 g d’acide hyaluronique dans un individu de 70 kg, dont 5 g sont remplacés par jour. En raison d’une dégradation rapide sa durée de vie est de moins d’une journée. Le stock d’acide hyaluronique est naturellement et constamment renouvelé, mais le rythme de ce renouvellement diminue avec l’âge et les agressions externes.
It is thus necessary to act very early and sustain an optimal hyaluronic acid turnover, similar to young skin.
