The hyaluronic acid is a natural polysaccharide that belongs to the group of the glycosaminoglycan, present in different live tissues. It plays an important role in the structure of the skin being responsible for the elasticity of the skin.
The hyaluronic acid has the capacity to retain water in thousands of times its molecular weight contributing volume and favoring the epidermis hydration. Due to its viscosity it ensures the cohesion of the conjunctive cells. It is an activator of the fibroblastic function and of the synthesis of collagen as well as of other factors of cutaneous growth slowing the natural aging processes.
