Hyaluronic acid is an important structural component of articular cartilage and an essential building block of the deep layer of our skin – the dermis. It is responsible for the smoothness of the skin due to its ability to bind large amounts of water molecules. Hyaluronic acid is able to bind water in an amount that is 1000 to 4000 times its own weight. This is much more than other natural or man-made substances can bind. In aesthetic medicine, hyaluronic fillers are used for lip augmentation, cheekbone shaping, wrinkle filling, chin contouring, non-surgical rhinoplasty, and overall facelift.
