HYALURONIC ACID

Hyaluronic acid is one of the primary factors of skin moisture, along with lipids, natural moisturizing factors, sebum, and aquaporin. As the predominant component in the extracellular matrix, hyaluronic acid plays a vital role in maintaining skin moisture. Already in the early development of the embryo, hyaluronic acid is formed and is thus 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. Furthermore, hyaluronic acid can influence cell metabolism. (1)
