HYALURONIC ACID

Hyaluronic acid is one of the primary factors of skin hydration, together with lipids, natural moisturizing factors, sebum and aquaporin. As the predominant component in the extracellular matrix, hyaluronic acid plays an essential role in maintaining skin hydration. Hyaluronic acid is already formed in the early development of the embryo and is therefore one of the first extracellular matrix components. In addition to its ability to bind water, the molecule acts as a lubricant during skin movements between the collagen and elastic fiber networks in the dermis. Hyaluronic acid can also influence cell metabolism. (1)
