Hyaluronic acid

Cross-linked hyaluronic acid (HA) known as hyaluronan or filler is a sterile physiological gel. Thanks to its chemical bonds, it is more resistant to the natural enzymatic degradation of hyaluronidase,  β-D-glucuronidase, β-N, acetylhexosaminidase and other non-enzymatic agents when compared to natural hyaluronic acid present in the human body. 

The polymer has the ability to link with water particles, which increases tissue volume and brings about the effect of filling and lifting, depending on the concentration

of the preparation and the area treated. Following a procedure with HA, the effect is instant and lasting, depending on the concentration administered into the tissue, as well as internal and external factors.
